(Thanks to Imed Chihi.) Guess a similar pattern for future years,
namely, DST is not observed in Ramadan, nor in the days following the
last Thursday before Ramadan, nor in the days preceding the first
Friday after Ramadan.

This works around Gnome bug 730332
<https://bugzilla.gnome.org/show_bug.cgi?id=730332>.
zic 2014c introduced the idea of generating a transition at the
minimum time value -2**63, to avoid ambiguities about what to do
before the first real transition. Through Glib release 2.40, the
interval_end function of Glib's gtimezone.c subtracts one from
this, to find the end time of the zeroth interval (i.e., the
interval containing all the "early" time stamps); this subtraction
typically overflows and wraps around to 2**63 - 1, which causes
Glib to go off the rails and assume that all time stamps are
"early". For example, Glib computes Sao Paulo time stamps as if
Brazil's circa-1913 rules were still in effect.
(Thanks to Leonardo Chiquitto for reporting the bug.)
Work around the bug by not generating time stamps equal to -2**63.
Come to think of it, time stamps before the Big Bang are physically
suspect anyway, so don't generate time stamps before the Big Bang.
* Makefile (GCC_DEBUG_FLAGS): Add comment re BIG_BANG.

* zic.c (BIG_BANG): New macro.
(big_bang_time): New constant.

min_time, when deciding whether to output a time stamp.

* NEWS: Document this.
* africa (Egypt): Add rules for 2014 through 2038. They all
involve some guesswork, unfortunately.
* zic.c (writezone, outzone): Arrange things so that binary files
include "transition" entries for minimum time values; these
entries eliminate localtime guesswork in handling low-valued time
stamps. The bad news: binary files grow slightly as a result of
these changes. The good news: there are no changes in the output
of "zdump -v" applied to before-and-after versions of all the
binary files generated by a "make install".
