cog: Use g_malloc() instead of malloc()
...
malloc() needs stdlib.h, which isn't included here and the
memory is freed later with g_free() anyway.

cog: Improve RGB<->YCbCr matrixing
...
YCbCr->RGB now has a 'bits' setting, which controls the number
of bits used for the matrix coefficients. Choices are 6 or 8.
6 is low quality, but faster.
RGB->YCbCr now works. Always works in 8 bit, since it's the same
speed as 6 bit.

cog: reset cache instead of returning NULL
...
Returning NULL makes things crash. Resetting the cache
makes things run slow. Still an underlying bug somewhere,
but not critical.
