f7bc0386d9 avcodec/ffv1enc: Fix out-of-bounds-array access 
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.

7033654f7f Use AV_PIX_FMT_FLAG_ALPHA for detecting transparency where nb_components was used 
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.

b6fc09cdb4 avcodec/ffv1: support of more pix_fmt

and it is not possible to know that the source file was with a smaller bit depth

58e16a4f4b avcodec/ffv1enc: mark RGB48 support as non-experimental 
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.

c1173437fc avcodec/ffv1enc: Fix storing RGB48 without explicitly set level 
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.

4bb1070c15 ffv1: Explicitly name the coder type 
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.
