videoconvert: renamed from colorspace

/* Video conversion functions
[MOVED FROM BAD 32/68] colorspace: Add conversion code Work in progress. Colorspace handles most format conversion using 3-stage getline/matrix/putline process using an AYUV or ARGB intermediate, with most functions handled by Orc. There is also a table of single-pass conversions, all handled by Orc. The plan is to add optional stages for various chroma upsampling/downsampling algorithms, dithering, and float/int16 intermediates, and then have Orc create multi-stage functions at runtime.
