[PATCH] SIGTERM handler

- Subject: [PATCH] SIGTERM handler
Hi,
This patch adds a handler for SIGTERM.
The main purpose is to ensure that GDB quit through quit_force() and
therefore properly disconnects from the target. This is quite important
for our target interface and should do no harm for anybody else's.
It also ensures that --return-child-result works when GDB exits this way.
Thanks
Andrew Stubbs
