mktime: port to stricter signed overflow checking
* lib/mktime.c: Omit 'pragma GCC optimize ("wrapv")'.
(long_int): Require width for INT_MAX * 3 * (seconds per year),
instead of merely for INT_MAX * 2. In practice platforms that
do the latter also do the former.
(TIME_T_MIN, TIME_T_MAX, TIME_T_MIDPOINT, SHR): Remove.
(shr): New static function, replacing SHR. All uses changed.
(mktime_min, mktime_max): New constants, replacing TIME_T_MIN
and TIME_T_MAX. All uses changed.
(ydhms_diff, guess_time_tm, ranged_convert, __mktime_internal):
Use long_int, not time_t.
(long_int_avg): New static function, replacing time_t_avg.
All uses changed. Round toward positive infinity, as that
generates slightly better code.
(time_t_add_ok, time_t_int_add_ok): Remove. All uses replaced
by INT_ADD_WRAPV.
(guess_time_tm): Accept time, not a pointer to it. All uses changed.
(convert_time): New static function.
(ranged_convert): Use it
(ranged_convert): Check for *T out of [mktime_min, mktime_max] range.
Use simpler test for loop exit.
(__mktime_internal): Store negative of guessed offset, to simplify
overflow checking. Remove no-longer-needed test for small time_t
overflows.

mktime: speed up DEBUG_MKTIME benchmarks
Call tzset just once, at the start, rather than for every test
case. This lets us measure the CPU cost of mktime as opposed to
that of tzset. This is relevant when TZ is not set and glibc is
being used. This speeds up tests by a factor of 40 on my Fedora
23 x86-64 platform.
* lib/mktime.c (main) [DEBUG_MKTIME]: Call localtime at the start,
to call tzset and as a sanity check. Later on, use localtime_r
instead of localtime.

(TYPE_IS_INTEGER, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM):
Remove. Use intprops.h defns instead.
(leapyear, isdst_differ, time_t_add_ok, time_t_int_ok):
Use bool for Boolean, for clarity.
(time_t_add_ok, time_t_int_add_ok): Use INT_ADD_WRAPV to
detect integer overflow.
* modules/mktime (Depends-on): Add intprops, stdbool, verify.

intprops, mktime, strtol: assume two's complement
These macros were not portable to every conforming C11 ones'
complement platform. It's not worth the hassle of porting to some
platforms that use ones' complement or signed magnitude, as such
platforms are almost purely theoretical nowadays and porting even
to some of them makes the code harder to review for little
practical benefit. Problem reported by Florian Weimer in:
https://sourceware.org/ml/libc-alpha/2016-04/msg00295.html
* lib/intprops.h (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT)
(TYPE_SIGNED_MAGNITUDE, _GL_INT_TWOS_COMPLEMENT):
* lib/mktime.c (TYPE_TWOS_COMPLEMENT):
* lib/strtol.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT)
(TYPE_SIGNED_MAGNITUDE):
Remove. All uses rewritten to assume two's complement, which is
all we can reasonably test nowadays anyway.
* top/maint.mk (_intprops_names): Remove the removed macros.

mktime: fix some integer overflow issues and sidestep the rest
This was prompted by a bug report by Benjamin Lindner for MinGW
<http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00472.html>.
His bug is due to signed integer overflow (0 - INT_MIN), and I
I scanned through mktime.c looking for other integer overflow
problems, fixing all the bugs I found.
Although the C Standard says the resulting code is still not safe
in the presence of integer overflow, in practice it should be good
enough for all real-world two's-complement implementations, except
for debugging environments that deliberately trap on integer
overflow (e.g., gcc -ftrapv).
* lib/mktime.c (WRAPV): New macro.
(SHR): Also check that long_int and time_t shift right in the
usual way, before using the fast-but-unportable method.
(TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove, no longer
used. The code already assumed two's complement, so there's
no need to test for alternatives. All uses removed.
(TYPE_MAXIMUM): Don't rely here on overflow behavior not defined by
the C standard. Problem reported by Rich Felker in
<http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00488.html>.
(twos_complement_arithmetic): Also check long_int and time_t.
(time_t_avg, time_t_add_ok, time_t_int_add_ok): New functions.
(guess_time_tm, ranged_convert, __mktime_internal): Use them.
(__mktime_internal): Avoid integer overflow with unary subtraction
in two instances where -1 - X is an adequate replacement for -X,
since the calculations are approximate.

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.

* 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.

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
