mpv/libmpcodecs/vd_qtvideo.c
sesse 45fd2e0457 Use the high-level QuickTime decoding APIs (DecompressSequenceFrameS and
friends) instead of the unsupported, internal ones (ImageCodecBeginBand
etc.). This is a prerequisite for, among others, Apple ProRes 4:2:2 support,
and simplifies the file by quite a bit.

Tested on Linux with all existing QuickTime codecs I could get to work in the
first place; qt261, qtavui, qtsvq3 have no change. qtcvid appears to not give
bit-exact the same output as before, but it looks just the same in playback
to me. qt3ivx stops crashing on exit (so works better than before). With some
extra patches and a codecs.conf entry, ProRes 4:2:2 also works, including on
Linux.

Since codec initialization is now actually done on decoder init instead of on
first frame, fallback should also work a bit better (although usually, qtvideo
is last in the chain). Also made the decoder complain explicitly if the
demuxer data is not there (ie., the user tried to run without -demuxer mov).

This patch is a cleaned up version of what Andrew Wason (rectalogic A
rectalogic D com) posted to mplayer-dev-eng in June.
