7a40442ad5 video: Add VYUY pixel format
This format is sometimes the output of JPEG decoders. It is the same as
YUY2 and UYVY but with a different component order.

5e752f4eda video-converter: fix interlaced scaling some more
Fix problem with the line cache where it would forget the first line in
the cache in some cases.
Keep as much backlog as we have taps. This generally works better and we
could do even better by calculating the overlap in all taps.
Allocated enough lines for the line cache.
Use only half the number of taps for the interlaced lines because we
only have half the number of lines.
The pixel shift should be relative to the new output pixel size so scale
it.

abb88801e7 video: add IYU2 format
This existed in 0.10 and is needed by dc1394src.

IYU2 format is a YUV fully-sampled packed format similar to v308
but with different component order (U-Y-V instead of Y-U-V).

079ceb894c video: add P010 format support
P010 is a YUV420 format with an interleaved U-V plane and 2-bytes per
component with the the color value stored in the 10 most significant
bits.

Changes since v2:
- Set bits=16 in DPTH10_10_10_HI
Changes since v1:
- Fixed x-offset calculation in uv.
- Added 6-bit shifts to FormatInfo.

83fe1c7705 video-converter: ignore matrix for RGB formats
For RGB formats, the matrix in the colorimetry (conversion from YUV to
RGB) is irrelevant and we should ignore it and assume the identity
transform for everything we do.

0d333d8d44 video-converter: add table based matrix8 implementation
Based on patch from Mozzhuhin Andrey <nopscmn at gmail.com>

Add a table based matrix8 multiplication implementation. The algorithm
does not do any clipping so we need to make sure we never call this on
input that might need to be clipped. In general, this algorithm is
2 times faster than the orc optimized one and would be chosen for all
RGB -> YUV conversions and some YUV->YUV and RGB->RGB conversions.
