The rationale is that you have a packed format in form
<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>
and shortening greyscale to 'G' might make one thing about Greenscale instead.
An alias pixel format and color space name are provided for compatibility.

The current hwaccel is broken and cannot be fixed in a compatible
way. It will be deprecated and replaced with a new one.

This avoids a dependancy of libavfilter on libavcodec

XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.

The pixel format descriptors are set to more or less arbitrary
values as bayer formats do not fit in the descriptors structure.
These values are currently not used for bayer formats and thus
do not matter.

This is required because there are some "holes" in the list for
compatibility with the fork.

The commit also removes the now unecessary check from cmdutils.

Make av_pix_fmt_descriptors table static on next major bump.

Making the table public is dangerous, since the caller has no way to
know how large it actually is. It also prevents adding new fields to
AVPixFmtDescriptor without a major bump.
