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.

40cf1bbacc Deprecate avctx.coded_frame 
The rationale is that coded_frame was only used to communicate key_frame,
pict_type and quality to the caller, as well as a few other random fields,
in a non predictable, let alone consistent way.

There was agreement that there was no use case for coded_frame, as it is
a full-sized AVFrame container used for just 2-3 int-sized properties,
which shouldn't even belong into the AVCodecContext in the first place.

The appropriate AVPacket flag can be used instead of key_frame, while
quality is exported with the new AVPacketSideData quality factor.
There is no replacement for the other fields as they were unreliable,
mishandled or just not used at all.

d6604b29ef Gather all coded_frame allocations and free functions to a single place 
Allocating coded_frame is what most encoders do anyway, so it makes
sense to always allocate and free it in a single place. Moreover a lot
of encoders freed the frame with av_freep() instead of the correct API
av_frame_free().

This bring uniformity to encoder behaviour and prevents applications
from erroneusly accessing this field when not allocated. Additionally
this helps isolating encoders that export information with coded_frame,
and heavily simplifies its deprecation.
