This is a second or alternative way that would allow us to deprecate J formats
without breaking AVCodec API. Instead of creating a monster struct with any
possible
color combination, I propose to supply a list of formats which have to be
interpreted
as full range, by adding a .pix_fmts_full to AVCodec. The old pix_fmts can
remain and
is compatible with current behaviour.
In this set there is also an additional structure that will allow to seamlessly
move
all color-related information from avcodeccontext to frame and then to avscale.
Note that the API for handling the second list is not yet implemented as I
wanted to
get some feedback for it.
Cheers,
Vittorio

lavu: Move all color-related enums to AVPixFmtModel
avframe: add COLOR side data
WIP: add .pix_fmts_full for the list of full range colors
lavu: add deprecation guards to full scale formats
