New module 'time', so that apps can include <time.h> as per
POSIX and GNU instead of separate include files like time_r.h
and timegm.h. This implementation tries out a simpler approach
for replacing decls in standard include files (as compared to
the string module), somewhat as an experiment.
* config/srclist.txt: Comment out mktime.c for now.
* doc/gnulib-tool.texi (Initial import): Don't use time_r as an example
since it doesn't apply any more. Use generic wording instead.
* MODULES.html.sh (Support for systems lacking POSIX:2001): New module
'time'.
* lib/time_.h, m4/time_h.m4, modules/time: New files.
* lib/strptime.h, lib/time_r.h, lib/timegm.h: Remove.
* lib/mktime.c: Include config.h depending on _LIBC, not HAVE_CONFIG_H.
Don't include <sys/types.h>; no longer needed since we assume C89.
* lib/mktime.c: Don't include "time_r.h"; no longer needed.
* lib/strftime.c: Likewise.
* lib/time_r.c: Likewise.
* lib/nanosleep.c (nanosleep): #undef after include files, not before.
* lib/nanosleep.c: Include <time.h> first, to check interface.
* lib/strptime.c: Likewise.
* lib/time_r.c: Likewise.
* lib/timegm.c: Likewise.
* lib/strptime.c: Don't include strptime.h or time_r.h; no longer
needed.
* lib/timegm.c: Don't include timegm.h; no longer needed.
* lib/timespec.h: Don't include <sys/time.h> before <time.h>;
time.h now handles any problems in that area.
(struct timespec, nanosleep): Remove; time.h now arranges for these.
* lib/xnanosleep.c: Don't include timespec.h; no longer needed now
that time.h defines struct timespec.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Check that nanosleep is declared.
Set REPLACE_NANOSLEEP. Don't AC_DEFINE nanosleep; the time module now
handles that.
* m4/strptime.m4 (gl_FUNC_STPRTIME): Set REPLACE_STRPTIME.
* m4/time_r.m4 (gl_TIME_R): Don't define HAVE_TIME_R_POSIX; no longer
needed. Set REPLACE_LOCALTIME.
* m4/timegm.m4 (gl_FUNC_TIMEGM): Set REPLACE_TIMEGM.
* m4/timespec.m4 (gl_CHECK_TYPE_STRUCT_TIMESPEC): Move to time_h.m4.
(gl_TIMESPEC): Don't check for sys/time.h or struct timespec or
nanosleep; time_h.m4 now does that. Don't require
gl_USE_SYSTEM_EXTENSIONS; no longer needed directly, and the time
module handles this now.
* modules/getdate (Depends-on): Remove timespec. Add time.
* modules/nanosleep (Depends-on): Likewise.
* modules/stat-time (Depends-on): Likewise.
* modules/nanosleep (Include): Include time.h, not timespec.h.
* modules/strptime (Files): Remove lib/strptime.h.
(Depends-on): Add extensions, time.
(Include): Include time.h, not strptime.h.
* modules/time_r (Files): Remove lib/time_r.h.
(Depends-on): Add time.
(Include): Include time.h, not time_r.h.
* modules/timegm: Likewise.
* modules/timespec (Description): Now does timespec-related decls
of our own, instead of struct timespec itself.
(Depends-on): Add time; remove extensions.
(Maintainer): Add self.
* modules/utimecmp (Depends-on): Add time; remove timespec.
* modules/utimens (Depends-on): Likewise.
* modules/xnanosleep (Depends-on): Likewise.

* config/srclist.txt: Temporarily comment out mktime.c until glibc bug
2821 is fixed.
* lib/mktime.c (guess_time_tm): Fix bug where mktime
returned the maximum time_t value rather than (time_t) -1.
Problem originally reported by William Bardwell
<http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
* m4/mktime.m4 (AC_FUNC_MKTIME): Sync from Autoconf.

(ranged_convert): Don't save conversion in a temporary struct.
This causes a warning with GCC 4.0.0, and anyway in the typical
case it's not worth the extra 100 bytes or so of code.
(ranged_convert, __mktime_internal): When calling a function via a
pointer P, use P () rather than (*P) (), as we now assume C89 or
better.

Fix some boundary cases and remove need for floating point.
Issue a compile-time diagnostic if time_t is floating point, or if
two's complement arithmetic is not in effect, or if arithmetic
right shift does not propagate the sign. These assumptions were
all in the original code but they weren't checked.
(TIME_T_MIDPOINT, verify): New macros.
(__isleap): Remove; it has integer overflow problems.
(leapyear): New function, without those problems.
(ydhms_tm_diff): Remove; splitting into two parts.
(ydhms_diff): New function, containing the arithmetic part of
the old ydhms_tm_diff function. Issue a compile-time
diagnostic if we are not using C99 integer division.
Avoid casts when possible.
(guess_time_tm): New function, containing the checking part of
the old ydhms_tm_diff function. Return the new value, rather than
the difference between it and the old. Accept a new argument T
so that *T specifies the old value. Check for overflow in the result.
(__mktime_internal): Use a time_t offset, not a long int offset.
This undoes the 2003-06-04 change, which is no longer needed now
that we have better overflow checking.
(localtime_offset): Likewise.
(__mktime_internal): Avoid harmful overflow on hosts where time_t
and long are 64-bit but int is only 32-bit.
(ydhms_diff): Use long int to store year1 and yday1.
Issue a compile-time diagnostic if long int is not wide enough.
(__mktime_internal): Use long int to store adjusted year and yday.
Use plain C rather than preprocessor commands, if that doesn't
affect efficiency.
Check for overflow (and try to repair) after each probe
rather than checking only at the very end. This avoids some bugs
(e.g., southern hemisphere, behind GMT, and GMT offset at minimum time
does not equal GMT offset at maximum time).
Use integer to check for overflow rather than floating point; this
is more portable to non-IEEE hosts, and is a tad faster.
When we detect that we are oscillating between two values,
don't check whether tm_isdst has the requested value, since
we already know the answer. When tm_isdst has the wrong value,
use a different heuristic to find the right one, based on the
extreme values actually observed in practice in tz2003a,
rather than the (overly optimistic) "previous 3 calendar quarters".
(not_equal_tm, print_tm, check_result): Use "const T" rather than
"T const" to accommodate glibc style.
(check_result): Use less-confusing report format. "long" -> "long int.
(main): Likewise.
Don't loop if the iteration overflows time_t.
Allow a negative step in the iteration.

Don't invoke localtime_r or gmtime_r unless it's the GNU C
library's localtime_r and gmtime_r; there are too many buggy
