Use sigaction module rather than signal(). * modules/c-stack (Depends-on): Add sigaction. * modules/fatal-signal (Depends-on): Likewise. * modules/nanosleep (Depends-on): Likewise. * modules/sigprocmask (Files): Add sig-handler.h. * modules/sigaction (Files): Likewise. * lib/sig-handler.h (get_handler): New file, suggested by Paul Eggert. * lib/c-stack.c (SIGACTION_WORKS): Simplify conditions. (c_stack_action) [!SIGACTION_WORKS]: Use sigaction, not signal. * lib/fatal-signal.c (uninstall_handlers, install_handlers) (init_fatal_signals): Likewise. * lib/nanosleep.c (rpl_nanosleep): Likewise. (siginterrupt): Delete fallback. * lib/sigprocmask.c (handler_t): Delete. (old_handlers): Use sa_handler_t instead. * m4/nanosleep.m4 (gl_PREREQ_NANOSLEEP): Drop check for siginterrupt.
