timezone actually has a daylight-savings rule.  This avoids breaking
cases that used to work because they went through the DecodePosixTimezone
code path.  Per contrib regression failures (mea culpa for not running
those yesterday...).  Also document the already-applied change to allow
GMT offsets up to 14 hours.

input routines.  Remove the former "DecodePosixTimezone" function in favor of
letting the zic code handle POSIX-style zone specs (see tzparse()).  In
particular this means that "PST+3" now means the same as "-03", whereas it
used to mean "-11" --- the zone abbreviation is effectively just a noise word
in this syntax.  Make sure that all named and POSIX-style zone names will be
parsed as a single token.  Fix long-standing bogosities in printing and input
of fractional-hour timezone offsets (since the tzparse() code will accept
these, we'd better make 'em work).  Also correct an error in the original
coding of the zic-zone-name patch: in "timestamp without time zone" input,
zone names are supposed to be allowed but ignored, but the coding was such
that the zone changed the interpretation anyway.

example SET TIME ZONE 'america/new_york' works now.  This seems a good
idea on general user-friendliness grounds, and is part of the solution
to the timestamp-input parsing problems I noted recently.
