[PATCH] Force rda (for unix) to exit when debugged program exits

[Kevin Buettner <kevinb@redhat.com>]

I've just committed the patch below.  I found this patch necessary to
make RDA exit when debugging via a serial connection upon which CLOCAL
had been set.  CLOCAL causes the hardware modem control signals to be
ignored.  As a consequence, the serial port will always appear to
be open.

	* server.c (main): Set ``server_quit_p'' when debugged process
	exits or terminates.
