Add subtransaction handling for table synchronization workers.

Since the old logic was completely unaware of subtransactions, a
change made in a subsequently-aborted subtransaction would still cause
workers to be stopped at toplevel transaction commit.  Fix that by
managing a stack of worker lists rather than just one.
