  lavu: add all color-related enums to AVFrame

Conflicts:
	libavcodec/avcodec.h
	libavutil/frame.c
	libavutil/frame.h
	libavutil/version.h

The version check is changed so they are available with the current ABI
FFmpeg libs should have no problems with added fields, nor should any
application using the libs, and we regularly added fields in the past.
We also moved 2 of these fields to AVFrame already previously without issues.

The other format (full flac header blocks) should not be exported by any
demuxers anymore.

This allows to drop an avpriv_ function and also simplify the following
commits.

Some encoders (e.g. flac) need to send side data when there is no more
data to be output. This enables them to output a packet with no data in
it, only side data.

the mpeg encoder would try to use them if vsad or vsse were selected for frame_skip_cmp
and frame_skip_threshold or frame_skip_factor were set to values != 0

example: "ffmpeg -i INPUT -c:v mpeg2video -skipcmp vsad -skip_threshold 1 -f null -"

Revert "avformat/movenchint: Fix movhinting with ff_rtp_chain_mux_open() from abb810db"

This has become unneeded due to f797b134

This reverts commit 1fe40e1b.

* commit 'f797b134':
  rtpenc_chain: Don't copy the time base to the source stream by default

See: 1fe40e1bMerged-by: Michael Niedermayer <michaelni@gmx.at>

Only copy it manually in the muxers where it makes sense (rtspenc,
sapenc). Don't touch the original AVStream in movenchint, where
the original AVStream should be kept untouched.

This fixes the normal tracks in RTP hinted files after
abb810db - the hint tracks were ok while the normal media tracks
were broken, noticed by Michael Niedermayer.

This reverts abb810db but achieves the same effect for the other
muxers.

It's needed for ff_svq1enc_init_x86() even if simd functions are disabled.

Alternatively, svq1enc_init.c could be made and the relevant code moved there.
