Make COMMIT/ROLLBACK a part of the transaction

Browse Source 
The transaction tracking now flags the transaction as open even when a
COMMIT/ROLLBACK is received. The next statement after the transaction is
closed resets the transaction state to inactive. This means that the end
of the transaction belongs in the transaction.

This allows all statements that belong to a transaction to be detected
with the transaction tracking functions provided by the core. With this,
the routing modules should have an easier time handling transactions.
