hook: add a generic hook right before we commit a transaction

We are adding a 'txnclose' hook that will be run right before a transaction is
closed. Hooks running at that time will have access to the full transaction
content through both 'hookargs' content and on-disk reading. They will be able
to abort the transaction.
