when decoding date fields.

Update the list of recognized time zones.
Document the range of arguments allowed for SET TIME ZONE.
Still need to add info on other date/time symbols (e.g. "AM", "T")
 and to freshen the docs on the date/time parsing rules.

 cases which should have worked but did not.
Now supports julian day (J2452271), ISO time labels (T040506) and various
 combinations of spaces and run-togethers of dates, times, and time zones.
All regression tests pass, and I have more tests to add after the 7.2
 release (don't want to require changes to the ancillary horology result
 files until after then).

'volatile' pointers to access those structures, so that optimizing
compilers will not decide to move the structure accesses outside of the
spinlock-acquire-to-spinlock-release sequence.  There are no known bugs
in these uses at present, but based on bad experience with lwlock.c,
it seems prudent to ensure that we protect these other uses too.
Per pghackers discussion around 12-Dec.  (Note: it should not be
necessary to worry about structures protected by LWLocks, since the
LWLock acquire and release operations are not inline macros.)
