So this replaces
signal-kill-the-obsolete-signal_unkillable-check-in-complete_signal.patch
2/3 is actually the same change, just the changelog was updated.

I'll try to send the cleanups tomorrow. sig_task_ignored() doesn't
look nice, sig_handler_ignored() must die, SIGNAL_UNKILLABLE checks
in sig_task_ignored() and get_signal() should be unified.

And to remind, we need to fix more problems I found yesterday.

Oleg.
