* modules/stdalign, modules/stdalign-h, modules/stdnoreturn:
* modules/stdnoreturn-h: Use more consistent deprecation
warnings, that do not recommend a different deprecated module.
C23 says <stdnoreturn.h> is obsolescent, so deprecate the
stdnoreturn module. I don't think it was being used anyway
as it had too many problems.
* modules/stdnoreturn: Mark as obsolete.
This is useful because Autoconf macros defined in *.m4 files can be
AC_REQUIREd. In the configure file, they are then expanded before
gl_INIT, i.e. at a place where it is not known whether they are required
for the lib/ or for the tests/ directory (or both).
