Subject: [PATCH] signals: move handle_stop_signal() into send_signal()

Move handle_stop_signal() into send_signal().  This factors out a couple of
callsites and allows us to do further unifications.

Also, with this change specific_send_sig_info() does handle_stop_signal().
Not that this is really important, we never send STOP/CONT via send_sig() and
friends, but still this looks more consistent.

The only (afaics) special case is get_signal_to_deliver().  If the traced task
dequeues SIGCONT, it can re-send it to itself after ptrace_stop() if the
signal was blocked by debugger.  In that case handle_stop_signal() is
unnecessary, but hopefully not a problem.
