In addition to SIGINT, on Windows it is common to send a different signal,
SIGBREAK, which has similar effects. This can be triggered by pressing
Ctrl+Break or by another process sending a signal.
New process groups on WIn32 usually ignore SIGINT; it is customary to stop
a process in a separate process group by sending SIGBREAK.
The attached patch makes ffmpeg.exe respond to SIGBREAK in the same way it
does SIGINT, using the WIndows console "control event" handler.
