Add a simple helper force_fatal_sig that causes a signal to be

Reimplement force_sigsegv based upon this new helper.

Can you just make the old force_sigsegv() go away? The odd special
casing of SIGSEGV was odd to begin with, I think everybody really just
wanted this new "force_fatal_sig()" and allow any signal - not making
SIGSEGV special.

Also, I think it should set SIGKILL in p->pending.signal or something
like that - because we want this to trigger fatal_signal_pending(),
don't we?

Right now fatal_signal_pending() is only true for SIGKILL, I think.
