commit bf17a5d2c707e8cd031d2a1dba2709b50452ba0c

runtime: switch to deferred STP_EXIT signalling
The former code allowed stapio to have two concurrent commands sent
toward the runtime at the same time: one from the main loop and
another one from the signal handling thread. This is suspected to
have caused occasional lockups. This new code switches to a deferred
signal handling model, where the signal handling thread merely
increments a counter, and the main loop monitors that count.
Unfortunately, this currently involves switching the main loop's
blocking /.ctl read into a nonblocking poll.
* runtime/staprun/mainloop.c (pending_interrupts): New variable.
(signal_thread): Increment it.
(stp_main_loop): Check it.
