Updates to named snapshot implementation:
* Allow a snapshot from a running transaction, but enforce that
the transaction is and remains read only.
* Enhance test cases
* Fixup locking, so a call to snapshot appears atomic (i.e: drop and create
are wrapped in a single lock)
* Fixup naming in named snapshot source file to be consistent.
