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.

e72a01e949 video-converter: Add support for 16 bits formats 
Rework the way we track the current state of the video through the
different conversion phases and use this to make sure we use the right
format and pstride where needed.

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.

f04a9589d4 video: add video blend helper functions to docs 
I don't think those were ever meant to be made public,
but they are, so we might as well document them.

b3ff9c030f video-converter: align offsets to subsampling 
Only apply an offset that is a multiple of the subsampling. To handle
arbitrary offsets in the future, we need to be able to chroma-resample
part of the borders.

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.

ca2bd1cc6b video-scaler: rename resampler to video-resampler 
Prefix the resampler with video-. It we would like to reuse the
resampler for audio later, we can copy/move it and deprecate this
one.

549bdd4ece video-converter: rework the generic converter function 
Use a LineCache object to track and process lines between unpack,
upsample, convert, downsample and pack stages. This simplifies the
main core processing function a lot and allows for future additions
easily.

Add support for interlaced formats in chroma up and downsampling.

When the xpos is given as greater than or equal to the video size,
we get a segfault, due to improper condition.
Hence adding proper conditions.
