rct: rework the verification preparation process

Browse Source 
The whole rct data apart from the MLSAGs is now included in
the signed message, to avoid malleability issues.

Instead of passing the data that's not serialized as extra
parameters to the verification API, the transaction is modified
to fill all that information. This means the transaction can
not be const anymore, but it cleaner in other ways.
