Log:
Implement CopyOnto semantics for both transactions and splits.

 - Export xaccFreeTransaction(), at least in the "private" header, since
it's the only correct thing to do with a duped Transaction that you
don't want to keep.
 - In addition, add xaccTransCopyOntoAndChangeAccount() which is just
what is needed for copying a transaction from one account into another.
