      Fix a malloc race condition involving strsignal. · aa1ba90e
      Paul Eggert authored
      A signal can arrive in the middle of a malloc, and Emacs's signal
      handler can invoke strsignal, which can invoke malloc, which is
      not portable.  This race condition bug makes Emacs hang on GNU/Linux.
      Fix it by altering the signal handler so that it does not invoke
      strsignal.
      * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
      * process.c (status_message): Use const pointer, in case strsignal
      is #defined to safe_strsignal.
      * sysdep.c (sys_siglist, init_signals): Always define and
      initialize a substitute sys_siglist if the system does not define
      one, even if HAVE_STRSIGNAL.
      (safe_strsignal): Rename from strsignal.  Always define,
      using sys_siglist.  Return a const pointer.
      * syssignal.h (safe_strsignal): New decl.
      (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
