cecb900704 video-format: fix pack of 4:2:0 formats
When packing 4:2:0 formats, we need to take the chroma from the even
lines, for the odd lines we only take luminance.

bd6d2b40d1 video-scaler: add support for 16bits formats
Add scaler functions for 16 bits formats.
Rename the scaler functions so that 16bits versions don't look too
weird.
Remove old unused h_2tap functions
Fix v_ntap functions, it was using 1 tap too little.

2f38f83c08 video-orc: comment out unused function
A faster version of 4tap horizontal scaling causes segfaults in ORC
presumably because it uses too many registers so disable it to avoid
crashing in the ORC tests.

49d909dabf video-scaler: add more ORC functions
Add the old ORC functions for nearest and linear. Label them as Low
quality because they are not as accurate but ORC lacks opcodes to
express this for now.

a high quality 12 bits and a low quality 6 bits version.

07d1d7ba38 video: improve YUV -> RGB conversion
Reorganize orc instructions to free up some registers.
We can reuse the ORC code to implement the generic AYUV->ARGB matrix.

b2fd20c416 video: move videoconvert code to video library
Move the conversion code used in videoconvert to the video library
and expose a simple but generic API to do arbitrary conversion. It can
currently do colorspace conversion but the plan is to add videoscale to
it as well.

fae9d82515 video-format: fix NV24 pack/unpack function
We can't reuse the NV12 functions, we need to make new ones.

97784b1563 video-format: fix NV16 unpack
We can just use the NV12 functions, the only difference is the
vertical subsampling.

separate subsampling step.
