  Add and change modules to make it easier for coreutils to use
  gnulib-tool.
  
  * lib/cycle-check.h: Include <stdint.h> unconditionally, since we
  now assume the stdint module.  Do not include inttypes.h.
  * lib/fsusage.h: Likewise.
  * lib/getndelim2.c: Likewise.
  * lib/human.h: Likewise.
  * lib/inttostr.h: Likewise.
  * lib/obstack.c: Likewise.
  * lib/regex_internal.h: Likewise.
  * lib/tempname.c: Likewise.
  * lib/utimecmp.c: Likewise.
  * lib/xstrtol.h: Likewise.
  
  * lib/stat_.h: Fix typo: HAVE_FUNC_LSTAT -> HAVE_LSTAT.
  
  * lib/strtoimax.c: Adjust to macro name changes in Autoconf,
  e.g., HAVE_LONG_LONG -> HAVE_LONG_LONG_INT.
  * lib/xtime.h: Likewise.
  
  Remove files that are no longer needed by their respective modules.
  * m4/obstack.m4: Remove.
  * m4/strerror_r.m4: Remove.
  * m4/uint32_t.m4: Remove.
  * m4/uintptr_t.m4: Remove.
  * m4/ullong_max.m4: Remove.
  * m4/xstrtoimax.m4: Remove.
  * m4/xstrtoumax.m4: Remove.
  
  * cycle-check.m4 (gl_CYCLE_CHECK): Do not require gl_AC_TYPE_UINTMAX_T,
  gl_STRUCT_DEV_INO, or gl_SAME_INODE, since gnulib dependencies now
  capture this.
  
  * cycle-check.m4 (gl_CYCLE_CHECK):
  Do not use AC_LIBSOURCES, since gnulib modules now do this.
  * fsusage.m4 (gl_FSUSAGE): Likewise.
  * human.m4 (gl_HUMAN): Likewise.
  * inttostr.m4 (gl_INTTOSTR): Likewise.
  * xstrtol.m4 (gl_XSTRTOL): Likewise.
  
  * filemode.m4 (gl_FILEMODE): Require AC_STRUCT_ST_DM_MODE.
  
  * filemode.m4 (gl_PREREQ_FSUSAGE_EXTRA): Do not require
  gl_AC_TYPE_INTMAX_T or gl_AC_TYPE_UINTMAX_T, since we now require
  stdint.
  * human.m4 (gl_HUMAN): Likewise.
  * inttostr.m4 (gl_PREREQ_INTTOSTR): Likewise.
  * mkstemp.m4 (gl_PREREQ_TEMPNAME): Likewise.
  * strtoimax.m4 (gl_PREREQ_STRTOIMAX): Likewise.
  * strtoumax.m4 (gl_PREREQ_STRTOUMAX): Likewise.
  * xstrtol (gl_XSTRTOL): Likewise.
  
  * gethrxtime.m4 (gl_XTIME): gl_AC_TYPE_LONG_LONG ->
  AC_TYPE_LONG_LONG_INT.
  * strtoimax.m4 (gl_PREREQ_STRTOIMAX): Likewise.
  * strtoll.m4 (gl_FUNC_STRTOLL): Likewise.
  * strtoull.m4 (gl_FUNC_STRTOULL): Likewise, for unsigned long.
  * strtoumax.m4 (gl_PREREQ_STRTOUMAX): Likewise.
  
  * human.m4 (gl_HUMAN): Do not require AM_STDBOOL_H since we depend
  on stdbool.
  
  * xstrtol.m4 (gl_PREREQ_XSTRTOL_H, gl_PREREQ_XSTRTOL): Remove.
  (gl_PREREQ_XSTRTOUL): Remove.
  
  * ls-mntd-fs.m4 (gl_LIST_MOUNTED_FILE_SYSTEMS): Check for hasmntopt.
  
  * posixver.m4: Fix comment since head -1 now works even in POSIX mode.
  
  * modules/backupfile (Files): Remove m4/d-ino.m4.
  (Depends-on): Add d-ino.
