Niklas Haas af6d52eec6 swscale: use 16-bit intermediate precision for RGB/XYZ conversion

The current logic uses 12-bit linear light math, which is woefully insufficient
and leads to nasty postarization artifacts. This patch simply switches the
internal logic to 16-bit precision.

This raises the memory requirement of these tables from 32 kB to 272 kB.

All relevant FATE tests updated for improved accuracy.
