Implement proper time zone support

Browse source 
Cosmopolitan now supports 104 time zones. They're embedded inside any
binary that links the localtime() function. Doing so adds about 100kb
to the binary size. This change also gets time zones working properly
on Windows for the first time. It's not needed to have /etc/localtime
exist on Windows, since we can get this information from WIN32. We're
also now updated to the latest version of Paul Eggert's TZ library.

E.g., suppose a non-POSIX.1-2017 rule applies from 2012 on with transitions
in March and September, plus one-off transitions in November 2013.
If zic looked only at the last 400 years, it would set max_year=2413,
with the intent that the 400 years 2014 through 2413 will be repeated.
The last transition listed in the tzfile would be in 2413-09,
less than 400 years after the last one-off transition in 2013-11.
Two years is not overkill for localtime.c, as a one-year bump
would mishandle 2023d's America/Ciudad_Juarez for November 2422. */
