Bugfix: sig_mask not calling into the OS.

This is just amazingly broken; sig_mask recurses instead
of calling sigprocmask.

Also, we need a way to reload the signal mask cache from the
kernel, because the kernel can change the signal mask behind
our back.

* signal.c (sig_reload_cache): New static function.
(sig_handler): Call sig_reload_cache to ensure the
sig_blocked_cache accurately reflects the currently
blocked signal set.
(sig_init): Call sig_reload_cache at init time to
correctly reflect any blocked signals.
(sig_mask): Call sigprocmask instead of recursing. Moreover,
the correct op code is SIG_SETMASK, not SIG_BLOCK.
