  alignasof: new module
  
  This splits off support for the C23 keywords alignas and alignof,
  from the now-deprecated stdalign module.  The latter now merely
  provides C11 support.
  * MODULES.html.sh, NEWS, doc/gnulib.texi:
  * doc/posix-headers/stdalign.texi: Document the change.
  * lib/stdalign.in.h: Remove most of the definitions (which are now
  supplied by the alignasof module), leaving only
  __alignas_is_defined and __alignof_is_defined.
  * modules/alignasof, modules/alignasof-tests: New files.
  * m4/stdalign.m4 (gl_ALIGNASOF): New macro, with
  most of the contents of the old gl_STDALIGN_H.
  Do not define __alignas_is_defined or __alignof_is_defined.
  (gl_STDALIGN_H): Rely on gl_ALIGNASOF for most of the work.
  * modules/alignalloc, modules/alignof, modules/argp:
  * modules/crypto/md4-buffer, modules/crypto/md5-buffer:
  * modules/crypto/sha1-buffer, modules/crypto/sha256-buffer:
  * modules/crypto/sha512-buffer, modules/crypto/sm3-buffer:
  * modules/fts, modules/rawmemchr, modules/relocatable-prog-wrapper:
  * modules/stddef-tests, modules/sys_socket:
  Depend on alignasof, not stdalign.
  * modules/stdalign: Deprecate.  Depend on alignasof.
  * modules/stdalign-tests: Move most contents to the new module
  alignasof-tests, and depend on that.
