player: fatal error if linked and compiled FFmpeg versions mismatch

Browse Source 
We don't support this anymore.

This tries to exit in a controlled way after command line options are
applied in order to honor logging options and, in case of libmpv, not to
kill the host. Not sure if it would be better to just vomit text to
stderr and call abort().
