  sig2str: Align with POSIX:2024.
  
  * lib/signal.in.h (SIG2STR_MAX): New macro.
  (sig2str, str2sig): New declarations.
  * lib/sig2str.h: Don't include intprops.h.
  (SIG2STR_MAX): Remove macro.
  (sig2str, str2sig): Remove declarations.
  * lib/sig2str.c: Include <signal.h> as the specification header.
  * m4/signal_h.m4 (gl_SIGNAL_H): Test whether sig2str, str2sig are
  declared.
  (gl_SIGNAL_H_REQUIRE_DEFAULTS): Initialize GNULIB_SIG2STR.
  (gl_SIGNAL_H_DEFAULTS): Initialize HAVE_SIG2STR, HAVE_STR2SIG.
  * m4/sig2str.m4 (gl_FUNC_SIG2STR): Require gl_SIGNAL_H_DEFAULTS. Check
  also for str2sig. Set HAVE_SIG2STR, HAVE_STR2SIG.
  * modules/signal-h (Makefile.am): Substitute GNULIB_SIG2STR,
  HAVE_SIG2STR, HAVE_STR2SIG.
  * modules/sig2str (Depends-on): Add signal-h. Remove intprops.
  (configure.ac): Test HAVE_SIG2STR, HAVE_STR2SIG. Invoke
  gl_SIGNAL_MODULE_INDICATOR.
  (Include): Add <signal.h>.
  * doc/posix-functions/sig2str.texi: Mention as implemented through the
  sig2str module.
  * doc/posix-functions/str2sig.texi: Likewise.
