P016 is the 16-bit variant of NV12 (planar luma, packed chroma), using
two bytes per component.

It may, and in fact is most likely to, be used in situations where
there are less than 16 bits of data. It is the responsibility of
the writer to zero out any unused LSBs.

Based on 7471352f by Luca Barbato.

This way, Doxygen is happier as aliases are now grouped together, and
it never handled #define's in an enum well in the first place.

Y400A already exists as an enum assignment.

P010 is the 10-bit variant of NV12 (planar luma, packed chroma), using two
bytes per component to store 10-bit data plus 6-bit zeroes in the LSBs.

Drop ST from names and symbols, it does not add anything distinctive or

based on the standardization in ARIB STD-B67:

The choice of enum value of 18 is consistent with HEVC:

The implementation assumes a nominal input range of [0, 1], which is
consistent with HEVC.

The h264/hevc Annex E colour primaries table says that AVCOL_SPC_SMPTE170M is
similar than AVCOL_SPC_SMPTE240M. These two values are not similar than
AVCOL_SPC_BT470BG.

Deprecated in 10/2012.

Deprecate older VA pixel formats (MOCO, IDCT) as it is now very unlikely
to ever be useful in the future. Only keep plain AV_PIX_FMT_VAAPI format
that is aliased to the older VLD variant.

This is an API change.

This was probably broken some time ago. The breakage is now part of the
ABI. For example, we have:

    AV_PIX_FMT_XYZ12BE
    AV_PIX_FMT_NV16
    AV_PIX_FMT_NV20LE

AV_PIX_FMT_NV20LE is wrong. It has the value 113, but as little-endian
format it should be even. This must have been quite obvious when these
formats were added (because of the AV_PIX_FMT_XYZ12BE entry), but
nobody cared or knew about this.

The future libavutil major bump will also break this additionally,
because disabling FF_API_VDPAU will remove an odd number of entries from
the middle of the enum.
