Splitting libav-tools

[Andres Mejia]

I believe the libav-tools package should be split and the separate
binary programs each be installed in their own package. Out of all the
programs from libav/ffmpeg, I've rarely used ffplay, and I never used
the server or probe programs. It would also help if the server be it's
own package, complete with sysvinit (or systemd or upstart) scripts.

Thoughts?
