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.

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.

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.

express this for now.

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.
