Code cleanup for assign_transaction_read_only.

As in commit fb4c5d2798730f60b102d775f22fb53c26a6445d on 2011-01-21,
this avoids spurious debug messages and allows idempotent changes at
any time.  Along the way, make assign_XactIsoLevel allow idempotent
changes even when not within a subtransaction, to be consistent with
the new coding of assign_transaction_read_only and because there's
no compelling reason to do otherwise.

Kevin Grittner, with some adjustments.
