never remember what it stands for.
(sig_handle_tty_stop): Remove obsolete call to sig_handle_tty_stop.
(_cygtls::call_signal_handler): Rework to grab signal information from
_main_tls if none is set for _my_tls.  Try harder to keep thread locked.
(reset_signal_arrived): Delete.
* fhandler.cc (fhandler_base_overlapped::wait_overlapped): Use new cygWFMO call
to wait for an event + standard cygwin stuff.  Modify debug output to
acccomodate new function.
* fhandler_console.cc (fhandler_console::read): Replace WaitForMultipleObjects
with cygWFMO.
* fhandler_socket.cc (get_inet_addr): Add comment.
* gendef (_sigdelayed): Remove call to reset_signal_arrived.
* sigproc.cc (_cygtls::signal_exit): Don't close my_readsig here unless we're
in the signal thread.
(create_signal_arrived): Create signal_arrived as auto-reset so that only one
thread is woken when a signal arrives.
* sigproc.h (cygWFMO): New function.
(reset_signal_arrived): Delete declaration.
