Make it clearer in the naming and documentation of the plug_bulk_checkin and unplug_bulk_checkin APIs that they can be thought of as a "transaction" to optimize operations on the object database. These transactions may be nested so that subsystems like the cache-tree writing code can optimize their operations without caring whether the top-level code has a transaction active. Add a flush_odb_transaction API that will be used in update-index to make objects visible even if a transaction is active. The flush call may also be useful in future cases if we hold a transaction active around calling hooks.
