libavcodec/ffv1enc.c accessed an array of uint8_t [32] via array[0][j]
in order to loop over all the uint8_t in this array of arrays. Of course
this implied an out-of-bounds access for array[0] and UBSan complained
about this. So replace this with nested loops; furthermore, factor this
out into a function of its own to easily break out of the nested loops.
This affected the FATE-tests vsynth1-ffv1, vsynth1-ffv1-v3-yuv420p,
vsynth1-ffv1-v3-yuv422p10, vsynth1-ffv1-v3-yuv444p16,
vsynth1-ffv1-v3-bgr0, vsynth1-ffv1-ffv1-v3-rgb48 as well as the
corresponding vsynth2-*, vsynth3-* and the vsynth_lena-* tests.

Temporarily keep the old method for ffmpeg_filters.c choose_pix_fmt and
avfiltergraph.c pick_format() until a paletted pixel format without alpha is
introduced.

The crc flag is only stored since version 3 thus before this crcs do not
work. We increase the version as needed same as we do with pix_fmts

Without direct support of such pix_fmt, content is padded to 16-bit
and it is not possible to know that the source file was with a smaller bit depth
so framemd5 is different

Resulting bitstream was tested with a conformance checker
using the last draft of FFV1 specifications.
Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
Also the files are already in the wild, and decoder support is
thus needed. And with decoders widely supporting it, there is no
advantage in not allowing it in the encoder.
The exact bitstream format may change in future versions of the
spec, if improvments are found.

Replace them with av_pix_fmt_get_chroma_sub_sample.

the bps value is only stored with level >= 1, using rgb48 with level 0 requires the
user app to keep track of the bps by external means, which does not always happen
also we force level >= 1 for other 16bps formats, so this is consistent.

The encoder produces bitstream compatible with the current specification
and version 2 is set as reserved (non-standardizable).

lavc: Move context_model to codec private options
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

Libav, for some reason, merged this as a public API function. This will
aid in future merges.
A define is left for backwards compat, just in case some person
used it, since it is in a public header.

This option is only used by ffv1 and ffvhuff.
It is a very codec-specific option, so deprecate the global variant.
Improve documentation a little.

Most option values are simply unused or ignored and in practice the
majory of codecs only need to check whether to enable rle or not.
Add appropriate codec private options which better expose the allowed

ffv1: Explicitly name the coder type

Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

FFv1 uses two types of coders, golomb and range with two different
tables. This is exposed this in a rather convoluted way, for example
mentioning to set coder type 1 while initializing the variable 'ac' to 2,
because encoder does not use range coder with default table.
Appropriate internal coder type values have been added and used in any
check rather than using raw numbers.
Initialization of avctx.coder_type in ffv1dec is removed because this
field is encoder only. An unneeded validation check in the encoder
is dropped too.
