fixed edge case where returning pre-HF2 transfer using HF2 CLI wallet _before_ HF2; bumped version

fixed boundary condition returning pre-HF2 TXs; removed a couple of extraneous vars; added a logging message; bumped version
fixed full reward zone buffer on fork transition to match between daemon and wallet

+## Introduction
+
+Salvium is a private, secure, untraceable, decentralised digital currency. You are your bank, you control your funds, and nobody can trace your transfers unless you allow them to do so.
+
+**Privacy:** Salvium uses a cryptographically sound system to allow you to send and receive funds without your transactions being easily revealed on the blockchain (the ledger of transactions that everyone has). This ensures that your purchases, receipts, and all transfers remain private by default.
+
+**Security:** Using the power of a distributed peer-to-peer consensus network, every transaction on the network is cryptographically secured. Individual wallets have a 25-word mnemonic seed that is only displayed once and can be written down to backup the wallet. Wallet files should be encrypted with a strong passphrase to ensure they are useless if ever stolen.
+
+**Untraceability:** By taking advantage of ring signatures, a special property of a certain type of cryptography, Salvium is able to ensure that transactions are not only untraceable but have an optional measure of ambiguity that ensures that transactions cannot easily be tied back to an individual user or computer.
+
+**Decentralization:** The utility of Salvium depends on its decentralised peer-to-peer consensus network - anyone should be able to run the salvium software, validate the integrity of the blockchain, and participate in all aspects of the salvium network using consumer-grade commodity hardware. Decentralization of the salvium network is maintained by software development that minimizes the costs of running the salvium software and inhibits the proliferation of specialized, non-commodity hardware.
+
+## About this project
+
+This is the core implementation of Salvium. It is open source and completely free to use without restrictions, except for those specified in the license agreement below. There are no restrictions on anyone creating an alternative implementation of Salvium that uses the protocol and network in a compatible manner.
+
+As with many development projects, the repository on GitHub is considered to be the "staging" area for the latest changes. Before changes are merged into that branch on the main repository, they are tested by individual developers in their own branches, submitted as a pull request, and then subsequently tested by contributors who focus on testing and code reviews. That having been said, the repository should be carefully considered before using it in a production environment, unless there is a patch in the repository for a particular show-stopping issue you are experiencing. It is generally a better idea to use a tagged release for stability.
+
+**Anyone is welcome to contribute to Salvium's codebase!** If you have a fix or code change, feel free to submit it as a pull request directly to the "master" branch. In cases where the change is relatively small or does not affect other parts of the codebase, it may be merged in immediately by any one of the collaborators. On the other hand, if the change is particularly large or complex, it is expected that it will be discussed at length either well in advance of the pull request being submitted, or even directly on the pull request.

+## Compiling Salvium from source
+
+### Dependencies
+
+The following table summarizes the tools and libraries required to build. A
+few of the libraries are also included in this repository (marked as
+"Vendored"). By default, the build uses the library installed on the system
+and ignores the vendored sources. However, if no library is found installed on
+the system, then the vendored source will be built and used. The vendored
+sources are also used for statically-linked builds because distribution
+packages often include only shared library binaries (`.so`) but not static
+library archives (`.a`).

+[1] On Debian/Ubuntu `libgtest-dev` only includes sources and headers. You must
+build the library binary manually. This can be done with the following command `sudo apt-get install libgtest-dev && cd /usr/src/gtest && sudo cmake . && sudo make`
+then:
+
+* on Debian:
+  `sudo mv libg* /usr/lib/`
+* on Ubuntu:
+  `sudo mv lib/libg* /usr/lib/`
+
+[2] libnorm-dev is needed if your zmq library was built with libnorm, and not needed otherwise

+
+### Cloning the repository
+
+Clone recursively to pull-in needed submodule(s):
+
+```
+git clone --recursive https://github.com/salvium/salvium
+```
+
+If you already have a repo cloned, initialize and update:
+
+```
+cd salvium && git submodule init && git submodule update
+```
+
+*Note*: If there are submodule differences between branches, you may need 
+to use `git submodule sync && git submodule update` after changing branches
+to build successfully.
+
+### Build instructions
+
+Salvium uses the CMake build system and a top-level [Makefile](Makefile) that
+invokes cmake commands as needed.
+
+#### On Linux and macOS
+
+* Install the dependencies
+* Change to the root of the source code directory, change to the most recent release branch, and build:
+
+    ```bash
+    cd salvium
+    git checkout v0.6.3
+    make
+    ```
+
+    *Optional*: If your machine has several cores and enough memory, enable
+    parallel build by running `make -j<number of threads>` instead of `make`. For
+    this to be worthwhile, the machine should have one core and about 2GB of RAM
+    available per thread.
+
+    *Note*: The instructions above will compile the most stable release of the
+    Salvium software. If you would like to use and test the most recent software,
+    use `git checkout master`. The master branch may contain updates that are
+    both unstable and incompatible with release software, though testing is always
+    encouraged.
+
+* The resulting executables can be found in `build/release/bin`
+
+* Add `PATH="$PATH:$HOME/salvium/build/release/bin"` to `.profile`
+
+* Run Salvium with `salviumd --detach`
+
+* **Optional**: build and run the test suite to verify the binaries:
+
+    ```bash
+    make release-test
+    ```
+
+    *NOTE*: `core_tests` test may take a few hours to complete.
+
+* **Optional**: to build binaries suitable for debugging:
+
+    ```bash
+    make debug
+    ```
+
+* **Optional**: to build statically-linked binaries:
+
+    ```bash
+    make release-static
+    ```
+
+Dependencies need to be built with -fPIC. Static libraries usually aren't, so you may have to build them yourself with -fPIC. Refer to their documentation for how to build them.
+
+* **Optional**: build documentation in `doc/html` (omit `HAVE_DOT=YES` if `graphviz` is not installed):
+
+    ```bash
+    HAVE_DOT=YES doxygen Doxyfile
+    ```
+
+* **Optional**: use ccache not to rebuild translation units, that haven't really changed. Salvium's CMakeLists.txt file automatically handles it
+
+    ```bash
+    sudo apt install ccache
+    ```
+
+#### On the Raspberry Pi
+
+Tested on a Raspberry Pi Zero with a clean install of minimal Raspbian Stretch (2017-09-07 or later) from https://www.raspberrypi.org/downloads/raspbian/. If you are using Raspian Jessie, [please see note in the following section](#note-for-raspbian-jessie-users).
+
+* `apt-get update && apt-get upgrade` to install all of the latest software
+
+* Install the dependencies for Salvium from the 'Debian' column in the table above.
+
+* Increase the system swap size:
+
+    ```bash
+    sudo /etc/init.d/dphys-swapfile stop  
+    sudo nano /etc/dphys-swapfile  
+    CONF_SWAPSIZE=2048
+    sudo /etc/init.d/dphys-swapfile start
+    ```
+
+* If using an external hard disk without an external power supply, ensure it gets enough power to avoid hardware issues when syncing, by adding the line "max_usb_current=1" to /boot/config.txt
+
+* Clone Salvium and checkout the most recent release version:
+
+    ```bash
+    git clone https://github.com/salvium/salvium
+    cd salvium
+    git checkout v0.6.3
+    ```
+
+* Build:
+
+    ```bash
+    USE_SINGLE_BUILDDIR=1 make release
+    ```
+
+* Wait 4-6 hours
+
+* The resulting executables can be found in `build/release/bin`
+
+* Add `export PATH="$PATH:$HOME/salvium/build/release/bin"` to `$HOME/.profile`
+
+* Run `source $HOME/.profile`
+
+* Run Salvium with `salviumd --detach`
+
+* You may wish to reduce the size of the swap file after the build has finished, and delete the boost directory from your home directory
+
+#### *Note for Raspbian Jessie users:*
+
+If you are using the older Raspbian Jessie image, compiling Salvium is a bit more complicated. The version of Boost available in the Debian Jessie repositories is too old to use with Salvium, and thus you must compile a newer version yourself. The following explains the extra steps and has been tested on a Raspberry Pi 2 with a clean install of minimal Raspbian Jessie.
+
+* As before, `apt-get update && apt-get upgrade` to install all of the latest software, and increase the system swap size
+
+    ```bash
+    sudo /etc/init.d/dphys-swapfile stop
+    sudo nano /etc/dphys-swapfile
+    CONF_SWAPSIZE=2048
+    sudo /etc/init.d/dphys-swapfile start
+    ```
+
+
+* Then, install the dependencies for Salvium except for `libunwind` and `libboost-all-dev`
+
+* Install the latest version of boost (this may first require invoking `apt-get remove --purge libboost*-dev` to remove a previous version if you're not using a clean install):
+
+    ```bash
+    cd
+    wget https://sourceforge.net/projects/boost/files/boost/1.72.0/boost_1_72_0.tar.bz2
+    tar xvfo boost_1_72_0.tar.bz2
+    cd boost_1_72_0
+    ./bootstrap.sh
+    sudo ./b2
+    ```
+
+* Wait ~8 hours
+
+    ```bash    
+    sudo ./bjam cxxflags=-fPIC cflags=-fPIC -a install
+    ```
+
+* Wait ~4 hours
+
+* From here, follow the [general Raspberry Pi instructions](#on-the-raspberry-pi) from the "Clone Salvium and checkout most recent release version" step.
+
+#### On Windows:
+
+Binaries for Windows are built on Windows using the MinGW toolchain within
+[MSYS2 environment](https://www.msys2.org). The MSYS2 environment emulates a
+POSIX system. The toolchain runs within the environment and *cross-compiles*
+binaries that can run outside of the environment as a regular Windows
+application.
+
+**Preparing the build environment**
+
+* Download and install the [MSYS2 installer](https://www.msys2.org), either the 64-bit or the 32-bit package, depending on your system.
+* Open the MSYS shell via the `MSYS2 Shell` shortcut
+* Update packages using pacman:
+
+    ```bash
+    pacman -Syu
+    ```
+
+* Exit the MSYS shell using Alt+F4
+* Edit the properties for the `MSYS2 Shell` shortcut changing "msys2_shell.bat" to "msys2_shell.cmd -mingw64" for 64-bit builds or "msys2_shell.cmd -mingw32" for 32-bit builds
+* Restart MSYS shell via modified shortcut and update packages again using pacman:
+
+    ```bash
+    pacman -Syu
+    ```
+
+
+* Install dependencies:
+
+    To build for 64-bit Windows:
+
+    ```bash
+    pacman -S mingw-w64-x86_64-toolchain make mingw-w64-x86_64-cmake mingw-w64-x86_64-boost mingw-w64-x86_64-openssl mingw-w64-x86_64-zeromq mingw-w64-x86_64-libsodium mingw-w64-x86_64-hidapi mingw-w64-x86_64-unbound
+    ```
+
+    To build for 32-bit Windows:
+
+    ```bash
+    pacman -S mingw-w64-i686-toolchain make mingw-w64-i686-cmake mingw-w64-i686-boost mingw-w64-i686-openssl mingw-w64-i686-zeromq mingw-w64-i686-libsodium mingw-w64-i686-hidapi mingw-w64-i686-unbound
+    ```
+
+* Open the MingW shell via `MinGW-w64-Win64 Shell` shortcut on 64-bit Windows
+  or `MinGW-w64-Win64 Shell` shortcut on 32-bit Windows. Note that if you are
+  running 64-bit Windows, you will have both 64-bit and 32-bit MinGW shells.
+
+**Cloning**
+
+* To git clone, run:
+
+    ```bash
+    git clone --recursive https://github.com/salvium/salvium
+    ```
+
+**Building**
+
+* Change to the cloned directory, run:
+
+    ```bash
+    cd salvium
+    ```
+
+* If you would like a specific [version/tag](https://github.com/salvium/salvium/tags), do a git checkout for that version. eg. 'v0.6.3'. If you don't care about the version and just want binaries from master, skip this step:
+
+    ```bash
+    git checkout v0.6.3
+    ```
+
+* If you are on a 64-bit system, run:
+
+    ```bash
+    make release-static-win64
+    ```
+
+* If you are on a 32-bit system, run:
+
+    ```bash
+    make release-static-win32
+    ```
+
+* The resulting executables can be found in `build/release/bin`
+
+* **Optional**: to build Windows binaries suitable for debugging on a 64-bit system, run:
+
+    ```bash
+    make debug-static-win64
+    ```
+
+* **Optional**: to build Windows binaries suitable for debugging on a 32-bit system, run:
+
+    ```bash
+    make debug-static-win32
+    ```
+
+* The resulting executables can be found in `build/debug/bin`
+
+### On FreeBSD:
+
+The project can be built from scratch by following instructions for Linux above(but use `gmake` instead of `make`). 
+If you are running Salvium in a jail, you need to add `sysvsem="new"` to your jail configuration, otherwise lmdb will throw the error message: `Failed to open lmdb environment: Function not implemented`.
+
+### On OpenBSD:
+
+You will need to add a few packages to your system. `pkg_add cmake gmake zeromq libiconv boost libunbound`.
+
+The `doxygen` and `graphviz` packages are optional and require the xbase set.
+Running the test suite also requires `py3-requests` package.
+
+Build salvium: `gmake`
+
+Note: you may encounter the following error when compiling the latest version of Salvium as a normal user:
+
+```
+LLVM ERROR: out of memory
+c++: error: unable to execute command: Abort trap (core dumped)
+```
+
+Then you need to increase the data ulimit size to 2GB and try again: `ulimit -d 2000000`
+
+### On NetBSD:
+
+Check that the dependencies are present: `pkg_info -c libexecinfo boost-headers boost-libs protobuf readline libusb1 zeromq git-base pkgconf gmake cmake | more`, and install any that are reported missing, using `pkg_add` or from your pkgsrc tree.  Readline is optional but worth having.
+
+Third-party dependencies are usually under `/usr/pkg/`, but if you have a custom setup, adjust the "/usr/pkg" (below) accordingly.
+
+Clone the salvium repository recursively and checkout the most recent release as described above. Then build salvium: `gmake BOOST_ROOT=/usr/pkg LDFLAGS="-Wl,-R/usr/pkg/lib" release`.  The resulting executables can be found in `build/NetBSD/[Release version]/Release/bin/`.
+
+### On Solaris:
+
+The default Solaris linker can't be used, you have to install GNU ld, then run cmake manually with the path to your copy of GNU ld:
+
+```bash
+mkdir -p build/release
+cd build/release
+cmake -DCMAKE_LINKER=/path/to/ld -D CMAKE_BUILD_TYPE=Release ../..
+cd ../..
+```
+
+Then you can run make as usual.
+
+### Building portable statically linked binaries
+
+By default, in either dynamically or statically linked builds, binaries target the specific host processor on which the build happens and are not portable to other processors. Portable binaries can be built using the following targets:
+
+* ```make release-static-linux-x86_64``` builds binaries on Linux on x86_64 portable across POSIX systems on x86_64 processors
+* ```make release-static-linux-i686``` builds binaries on Linux on x86_64 or i686 portable across POSIX systems on i686 processors
+* ```make release-static-linux-armv8``` builds binaries on Linux portable across POSIX systems on armv8 processors
+* ```make release-static-linux-armv7``` builds binaries on Linux portable across POSIX systems on armv7 processors
+* ```make release-static-linux-armv6``` builds binaries on Linux portable across POSIX systems on armv6 processors
+* ```make release-static-win64``` builds binaries on 64-bit Windows portable across 64-bit Windows systems
+* ```make release-static-win32``` builds binaries on 64-bit or 32-bit Windows portable across 32-bit Windows systems
+
+### Cross Compiling
+
+You can also cross-compile static binaries on Linux for Windows and macOS with the `depends` system.
+
+* ```make depends target=x86_64-linux-gnu``` for 64-bit linux binaries.
+* ```make depends target=x86_64-w64-mingw32``` for 64-bit windows binaries.
+  * Requires: `python3 g++-mingw-w64-x86-64 wine1.6 bc`
+  * You also need to run:  
+```update-alternatives --set x86_64-w64-mingw32-g++ x86_64-w64-mingw32-g++-posix && update-alternatives --set x86_64-w64-mingw32-gcc x86_64-w64-mingw32-gcc-posix```
+* ```make depends target=x86_64-apple-darwin``` for macOS binaries.
+  * Requires: `cmake imagemagick libcap-dev librsvg2-bin libz-dev libbz2-dev libtiff-tools python-dev`
+* ```make depends target=i686-linux-gnu``` for 32-bit linux binaries.
+  * Requires: `g++-multilib bc`
+* ```make depends target=i686-w64-mingw32``` for 32-bit windows binaries.
+  * Requires: `python3 g++-mingw-w64-i686`
+* ```make depends target=arm-linux-gnueabihf``` for armv7 binaries.
+  * Requires: `g++-arm-linux-gnueabihf`
+* ```make depends target=aarch64-linux-gnu``` for armv8 binaries.
+  * Requires: `g++-aarch64-linux-gnu`
+* ```make depends target=riscv64-linux-gnu``` for RISC V 64 bit binaries.
+  * Requires: `g++-riscv64-linux-gnu`
+* ```make depends target=x86_64-unknown-freebsd``` for freebsd binaries.
+  * Requires: `clang-8`
+* ```make depends target=arm-linux-android``` for 32bit android binaries
+* ```make depends target=aarch64-linux-android``` for 64bit android binaries
+
+
+The required packages are the names for each toolchain on apt. Depending on your distro, they may have different names. The `depends` system has been tested on Ubuntu 18.04 and 20.04.
+
+Using `depends` might also be easier to compile Salvium on Windows than using MSYS. Activate Windows Subsystem for Linux (WSL) with a distro (for example Ubuntu), install the apt build-essentials and follow the `depends` steps as depicted above.
+
+The produced binaries still link libc dynamically. If the binary is compiled on a current distribution, it might not run on an older distribution with an older installation of libc. Passing `-DBACKCOMPAT=ON` to cmake will make sure that the binary will run on systems having at least libc version 2.17.
+
+### Trezor hardware wallet support
+
+If you have an issue with building Salvium with Trezor support, you can disable it by setting `USE_DEVICE_TREZOR=OFF`, e.g., 
+
+```bash
+USE_DEVICE_TREZOR=OFF make release
+```
+
+For more information, please check out Trezor [src/device_trezor/README.md](src/device_trezor/README.md).
+
+### Gitian builds
+
+See [contrib/gitian/README.md](contrib/gitian/README.md).
+
+## Running salviumd
+
+The build places the binary in `bin/` sub-directory within the build directory
+from which cmake was invoked (repository root by default). To run in the
+foreground:
+
+```bash
+./bin/salviumd
+```
+
+To list all available options, run `./bin/salviumd --help`.  Options can be
+specified either on the command line or in a configuration file passed by the
+`--config-file` argument.  To specify an option in the configuration file, add
+a line with the syntax `argumentname=value`, where `argumentname` is the name
+of the argument without the leading dashes, for example, `log-level=1`.
+
+To run in background:
+
+```bash
+./bin/salviumd --log-file salviumd.log --detach
+```
+
+To run as a systemd service, copy
+[salviumd.service](utils/systemd/salviumd.service) to `/etc/systemd/system/` and
+[salviumd.conf](utils/conf/salviumd.conf) to `/etc/`. The [example
+service](utils/systemd/salviumd.service) assumes that the user `salvium` exists
+and its home is the data directory specified in the [example
+config](utils/conf/salviumd.conf).
+
+If you're on Mac, you may need to add the `--max-concurrency 1` option to
+salvium-wallet-cli, and possibly salviumd, if you get crashes refreshing.
+
+## Internationalization
+
+See [README.i18n.md](docs/README.i18n.md).
+
+## Debugging
+
+This section contains general instructions for debugging failed installs or problems encountered with Salvium. First, ensure you are running the latest version built from the GitHub repo.
+
+### Obtaining stack traces and core dumps on Unix systems
+
+We generally use the tool `gdb` (GNU debugger) to provide stack trace functionality, and `ulimit` to provide core dumps in builds which crash or segfault.
+
+* To use `gdb` in order to obtain a stack trace for a build that has stalled:
+
+Run the build.
+
+Once it stalls, enter the following command:
+
+```bash
+gdb /path/to/salviumd `pidof salviumd`
+```
+
+Type `thread apply all bt` within gdb in order to obtain the stack trace
+
+* If however the core dumps or segfaults:
+
+Enter `ulimit -c unlimited` on the command line to enable unlimited filesizes for core dumps
+
+Enter `echo core | sudo tee /proc/sys/kernel/core_pattern` to stop cores from being hijacked by other tools
+
+Run the build.
+
+When it terminates with an output along the lines of "Segmentation fault (core dumped)", there should be a core dump file in the same directory as salviumd. It may be named just `core`, or `core.xxxx` with numbers appended.
+
+You can now analyse this core dump with `gdb` as follows:
+
+```bash
+gdb /path/to/salviumd /path/to/dumpfile`
+```
+
+Print the stack trace with `bt`
+
+ * If a program crashed and cores are managed by systemd, the following can also get a stack trace for that crash:
+
+```bash
+coredumpctl -1 gdb
+```
+
+#### To run Salvium within gdb:
+
+Type `gdb /path/to/salviumd`
+
+Pass command-line options with `--args` followed by the relevant arguments
+
+Type `run` to run salviumd
+
+### Analysing memory corruption
+
+There are two tools available:
+
+#### ASAN
+
+Configure Salvium with the -D SANITIZE=ON cmake flag, eg:
+
+```bash
+cd build/debug && cmake -D SANITIZE=ON -D CMAKE_BUILD_TYPE=Debug ../..
+```
+
+You can then run the salvium tools normally. Performance will typically halve.
+
+#### valgrind
+
+Install valgrind and run as `valgrind /path/to/salviumd`. It will be very slow.
+
+### LMDB
+
+Instructions for debugging suspected blockchain corruption as per @HYC
+
+There is an `mdb_stat` command in the LMDB source that can print statistics about the database but it's not routinely built. This can be built with the following command:
+
+```bash
+cd ~/salvium/external/db_drivers/liblmdb && make
+```
+
+The output of `mdb_stat -ea <path to blockchain dir>` will indicate inconsistencies in the blocks, block_heights and block_info table.
+
+The output of `mdb_dump -s blocks <path to blockchain dir>` and `mdb_dump -s block_info <path to blockchain dir>` is useful for indicating whether blocks and block_info contain the same keys.
+
+These records are dumped as hex data, where the first line is the key and the second line is the data.
+
+# Known Issues
+
+## Protocols
+
+### Socket-based
+
+Because of the nature of the socket-based protocols that drive salvium, certain protocol weaknesses are somewhat unavoidable at this time. While these weaknesses can theoretically be fully mitigated, the effort required (the means) may not justify the ends. As such, please consider taking the following precautions if you are a salvium node operator:
+
+- Run `salviumd` on a "secured" machine. If operational security is not your forte, at a very minimum, have a dedicated a computer running `salviumd` and **do not** browse the web, use email clients, or use any other potentially harmful apps on your `salviumd` machine. **Do not click links or load URL/MUA content on the same machine**. Doing so may potentially exploit weaknesses in commands which accept "localhost" and "127.0.0.1".
+- If you plan on hosting a public "remote" node, start `salviumd` with `--restricted-rpc`. This is a must.
+
+### Blockchain-based
+
+Certain blockchain "features" can be considered "bugs" if misused correctly. Consequently, please consider the following:
+
+- When receiving salvium, be aware that it may be locked for an arbitrary time if the sender elected to, preventing you from spending that salvium until the lock time expires. You may want to hold off acting upon such a transaction until the unlock time lapses. To get a sense of that time, you can consider the remaining blocktime until unlock as seen in the `show_transfers` command.
