signal.h: always support 'volatile sig_atomic_t'
* m4/signal_h.m4 (gl_SIGNAL_H): Check for AIX limitation.
(gl_SIGNAL_H_DEFAULTS): Add a default.
* modules/signal (Makefile.am): Substitute if needed.
* lib/signal.in.h (sig_atomic_t): Redefine if needed, so that
users can blindly add volatile.
* doc/posix-headers/signal.texi (signal.h): Document it.
