        * libc/time/month_lengths.c: New file with __month_lengths array
        (previously mon_lengths array in mktm_r.c)
        * libc/time/tzcalc_limits.c: New file with __tzcalc_limits() from
        mktm_r.c
        * libc/time/lcltime_r.c (localtime_r): Simplify by changing call to
        _mktm_r() with call to gmtime_r() and code moved from _mktm_r() which
        was used to do time zone adjustments
        * libc/time/gmtime_r.c (gmtime_r): Simplify by moving all relevant
        code from _mktm_r(), breaking all dependencies on time zone related
        functions
        * libc/time/mktm_r.c: Delete file
        * libc/time/local.h: Update accordingly - remove declaration of
        _mktm_r(), add declaration of __month_lengths[]
        * libc/time/Makefile.am: Modify accordingly.
        * libc/time/Makefile.in: Regenerate.
