(my_strftime): If the underlying strftime returns 0
(which shouldn't happen), generate nothing instead of returning 0
immediately, so that nstrftime (NULL, ...) doesn't return 0.

Factor int-properties macros into a single file, except for
glibc-related files.
* lib/intprops.h: New file.
* lib/getloadavg.c: Include it instead of limits.h.
(INT_STRLEN_BOUND): Remove.
* lib/human.c: Include intprops.h.
(group_number): Use INT_STRLEN_BOUND instead of rolling it ourself.
* lib/human.h (LONGEST_HUMAN_READABLE): Use 146/485 rather than 302/1000.
* lib/inttostr.h: Include intprops.h instead of limits.h.
(INT_STRLEN_BOUND, INT_BUFSIZE_BOUND): Remove.
* lib/mktime.c (TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT): New macros,
for consistency with intprops.h.
(time_t_is_integer, twos_complement_arithmetic): Use them.
* lib/sig2str.h: Include <signal.h>, intprops.h.
(INT_STRLEN_BOUND): Remove.
* lib/strftime.c (TYPE_SIGNED): Remove.
(INT_STRLEN_BOUND): Switch to same implementation as intprops.h.
* lib/strtol.c: Adjust comments to match intprops.h.
* lib/userspec.c: Include intprops.h.
(TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Remove.
* lib/utimecmp.c, lib/xnanosleep.c, lib/xstrtol.c: Likewise.
* lib/utimecmp.c (utimecmp): Use TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT
instead of rolling our own expressions.
* lib/xstrtol.c: Include xstrtol.h first, to test interface.
* modules/getloadavg (Files): Add lib/intprops.h.
* modules/human (Files): Likewise.

Include <stdbool.h>. Use bool where appropriate,
instead of int.
(my_strftime): Do not mishandle years close to INT_MAX, by doing
the right thing even if adding 1900 would overflow. Similarly
for tm_mon + 1 and tm_yday + 1.
Make %Y always equivalent to %C%y, and similarly for %G and %g.
(DO_NUMBER, DO_NUMBER_SPACEPAD): Set digits to d, not a conditional.
(DO_SIGNED_NUMBER): New macro.
(my_strftime) [HAVE_TZNAME]: Don't dump core if tp->tm_dst > 1.

From Derek Price:
(pagealign_alloc): Set var to const as possible.
Check for MAP_FAILED return from mmap. Set errno on failure of
posix_memalign(). Catch munmap failure.

Remove workaround for bug in Linux kernel 2.6.8 or thereabouts.
The workaround isn't strictly needed for POSIX conformance, and
it's too much of a pain to configure and maintain. We'll ask
people to fix their kernels instead.
* modules/xnanosleep (Depends-on): Remove gethrxtime.
* lib/xnanosleep.c: Don't include gethrxtime.h or xtime.h.
(NANOSLEEP_BUG_WORKAROUND): Remove.
(xnanosleep): Remove the workaround.
* m4/xnanosleep.m4 (gl_XNANOSLEEP): Remove configuration attempting
to detect nanosleep bug.
* lib/gethrxtime.h, lib/gethrxtime.c, lib/xtime.h: New files.
* lib/timespec.h (gettime): Return void, since it always
succeeds now. All uses changed.
* lib/gettime.c (gettime) Likewise.
[HAVE_NANOTIME]: Prefer nanotime.
Assume gettimeofday succeeds, as POSIX requires.
Assime time () succeeds, since other code already does.
* lib/xnanosleep.c: Include xtime.h and gethrxtime.h, not xalloc.h.
(timespec_subtract): Remove.
(NANOSLEEP_BUG_WORKAROUND): New constant.
(xnanosleep): Use gethrxtime rather than gettime; this simplifies
things considerably. Use it only on GNU/Linux hosts, since the
workaround shouldn't be needed elsewhere.
* m4/gethrxtime.m4, m4/xnanosleep.m4: New files.
* m4/gettime.m4 (gl_GETTIME): Check for nanotime.

* modules/chdir-long (Depends-on): Add memrchr.

* lib/chdir-long.c: Include it.
* lib/memrchr.c [!defined _LIBC]: Include it rather than <string.h>
Don't bother including stddef.h.
* m4/memrchr.m4 (gl_FUNC_MEMRCHR): Add AC_LIBSOURCES, for memrchr.h.

Include <sys/types.h>, for dev_t.

(ME_DUMMY): Count "subfs" as a dummy. Problem reported by
Dmitry V. Levin.
Include mountlist.h first, to test the interface.
