Several encoders were multiplying the buffer size by 8, in order to get
a bit size. However, the buffer_size argument is for the byte size of
the buffer. We had experienced crashes encoding prores (Anatoliy) at
size 4096x4096.

As far as matrix coefficients are concerned, BT470BG and SMPTE170M
match BT601. This is similar to the check performed in vf_scale.

Change register constraint on the v variable from = to +. This was causing GCC
to think that the v variable was never read and therefore not initialize it.
This fixes about 20 fate failures on mips64el.

Remove some assembly that the compiler can easily handle optimally on its own.
GCC produces almost identical assembly.

Q_fract should have be declared as 'const float*'.
Also fix the constness of some local variables affected by this.

GCC is perfectly happy generating optimized multiplication code on its own for
64-bit arches. GCC refuses to optimize the loongson code when in 32-bit mode,
so I've left that.

This makes the sorting of the colors along an axis (r, g or b)
predictible, and thus testable under FATE. The performance is not really
an issue here since the function is called only once at the end and will
need to sort very small number of entries, so an alternative would be to
make the sorting functions (see DECLARE_CMP_FUNC()) fallback on another
axis in case of equality. This approach was actually simpler.
I don't know if there is any advantage in using a multidimensional sort,
but it will affect the final palette one way or another.
This avoids a null pointer dereference of pkt->data.
