module sys_time.
* lib/gethrxtime.c: Include <sys/time.h>, since we can no longer
assume timespec.h defines struct timeval.
* lib/settime.c: Likewise.
* lib/utimens.c: Likewise.
* lib/gettime.c (gettime): Remove test against HAVE_GETTIMEOFDAY,
since we now assume the gettimeofday module.
* lib/tempname.c (__gen_tempname): Likewise.
* lib/gettimeofday.h: Remove.
* lib/gettimeofday.c: Include <sys/time.h> instead of "gettimeofday.h".
Don't include <sys/types.h> and <stdlib.h>; shouldn't be needed.
Include <time.h>, for 'time()'.
(localtime_buffer_addr): Also use this workaround if
TZSET_CLOBBERS_LOCALTIME. Set to a dummy static variable by default,
to simplify the uses. All uses changed.
(localtime, gmtime, tzset, gettimeofday): Reformat slightly so
that #undef is inside {}, and 'const' follows type name consistently.
(tzset): Define replacement only if TZSET_CLOBBERS_LOCALTIME.
(gettimeofday): Do not use the maximum possible value for
tv->tv_usec, since that might break usages other than ls.c.
Instead, we'll leave ls.c alone. This undoes today's patch
by Bruno. Add a compile-time warning for 1s-clock resolution;
we've never observed the problem but might as well keep the
canary.

into the sys_time module. Check for gettimeofday just once.
Prefix our variables with gl_, not with ac_ or jm_. Tighten test
for gettimeofday signature to just check the signature. Merely
compile it, since linking doesn't test signature. Improve test for
whether gettimeofday.o is actually needed.
(gl_FUNC_GETTIMEOFDAY_CLOBBER): Renamed from
AC_FUNC_GETTIMEOFDAY_CLOBBER. All uses changed. Use
AC_RUN_IFELSE rather than AC_TRY_RUN. If clobbering, set
and define GETTIMEOFDAY_CLOBBERS_LOCALTIME.
(gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Don't define
GETTIMEOFDAY_CLOBBERS_LOCALTIME; that's gl_FUNC_GETTIMEOFDAY_CLOBBER's
job. Don't define tzset; that's gl_FUNC_TZSET_CLOBBER's job.
* m4/mktime.m4 (AC_FUNC_MKTIME): Just include <time.h> rather
