Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

Change ASF demuxer to return incomplete last packets.
Whether the behaviour for streams using scrambling makes sense
is unclear.

Return an error when get_buffer reads none or only partial data instead
of returning packets with uninitialized data.
Returning partial packets as for other demuxers is problematice due to
packet scrambling and thus is not done.
