Rewrite mktime from scratch for performance, and for correctness
in the presence of leap seconds.
* time/mktime.c (ydhms_tm_diff, not_equal_tm, print_tm, check_result):
New functions.
(LEAP_SECONDS_POSSIBLE, CHAR_BIT, INT_MIN, INT_MAX,
TIME_T_MIN, TIME_T_MAX, TM_YEAR_BASE, EPOCH_YEAR): New macros.
<limits.h>, <stdlib.h>: New #includes.
(main): Support tests with given broken-down value; support benchmarks.
(__mon_lengths, debugging_enabled, printtm, dist_tm, doit,
do_normalization, normalize, BAD_STRUCT_TM, SKIP_VALUE,
<ctype.h>): Remove.
* time/time.h, time/mktime.c (__mktime_internal): New offset arg.
* time/mktime.c (mktime), time/timegm.c (timegm): Use it.
* time/mktime.c (__mon_yday): New variable; replaces `__mon_lengths'.
time/offtime.c (__offtime), time/tzset.c (compute_change): Use it.
* time/offtime.c (__offtime): Remove useless assignment
`tp->tm_isdst = -1'.
* manual/maint.texi: Update credits.
