Back-patch assorted latch-related fixes.
Fix a whole bunch of signal handlers that had been hacked to do things that
might change errno, without adding the necessary save/restore logic for
errno. Also make some minor fixes in unix_latch.c, and clean up bizarre
and unsafe scheme for disowning the process's latch. While at it, rename
the PGPROC latch field to procLatch for consistency with 9.2.
Issues noted while reviewing a patch by Peter Geoghegan.
