Replace FFmpeg with Libav in licence headers
Signed-off-by: Mans Rullgard <firstname.lastname@example.org>
Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.
This also lists the objects from those two libraries as internal (by addingthe ff_ prefix) so that they can then be hidden via linker scripts.
split raw.c into rawdec.c and rawenc.c
