mycroft fb526e055c Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.
