Tom Lane fdd13f1568 Give the ResourceOwner mechanism full responsibility for releasing buffer

pins at end of transaction, and reduce AtEOXact_Buffers to an Assert
cross-check that this was done correctly.  When not USE_ASSERT_CHECKING,
AtEOXact_Buffers is a complete no-op.  This gets rid of an O(NBuffers)
bottleneck during transaction commit/abort, which recent testing has shown
becomes significant above a few tens of thousands of shared buffers.
