- The memcpy was completely wrong because
s->prob_ctx[s->framectxid].coef is a [4][2][2][6][6][3] array, whereas
s->prob.coef is a [4][2][2][6][6][11] array.
- The additional check was committed to ffmpeg by Ronald S. Bultje.

Now it is possible to adjust compression speed vs R/D when needed
and also skip vintage players compatibility at will.

This handles macroblock edges for the chroma components in the same way
as for the luma compoment for 4:4:4 streams. The Spec explicitly states
that the deblocking filter is not applied to edges at the boundary of
the picture.

Fixes these errors with nasm:
libavcodec/x86/lossless_videodsp.asm:86: error: invalid combination of opcode and operands

I don't know whether movd or movq was meant, but either way
maskq vs. maskd must match the mov size.

The default get_buffer2() implementation (and possibly some
user ones) does not allocate edges when this flag is set, which may
expose bugs in some decoders. Until the 10 release is out, it is safer
to remove this part.
The T-REC-H.265-2013044 page 79 states it has to be in the range
[-s->sps->qp_bd_offset, 51].

The src buffer should only contain values in the interval
[0, (1 << BIT_DEPTH) - 1].
Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in
the interval [0, 31], so no clip is needed.

The reconstructed picture should always be clipped (see section 8.6.5),
previously we did not clip coding units where
cu_transquant_bypass_flag == 1.

Otherwise it would overflow.

Fixes an issue where the B-frame coding mode switches from interlaced
fields to interlaced frames, causing incorrect decisions in the motion
compensation code and resulting in visual artifacts.
