Thomas Munro 88554c0911 Move RecoveryLockList into a hash table. ...

Standbys frequently need to release all locks held by a given xid.
Instead of searching one big list linearly, let's create one list
per xid and put them in a hash table, so we can find what we need
in O(1) time.

Earlier analysis and a prototype were done by David Rowley, though
this isn't his patch.

Back-patch all the way.
