Mainly ported from 8-bit H.264 MC Chroma.

Fixes encoder private options, which are broken now in ffmpeg, because
opt_default2() can't find them, thus making opt_default() to fail.

By observation it did not seem to handle prev_frame_num > frame_num.
This does not affect any files I have.

One of the causes of this bug is that the h264 parser defaults low_delay
to 1, but the h264 codec defaults low_delay to 0. Really Ugly.

After many hours of looking at this, I'm still not sure how has_b_frames
is *intended* to behave, but to me the implementation appears way more
complicated than it ought to be.

My patch relies on the encoder to set an optional field in the SPS. This
works for libx264 streams, but I'm not sure that all h264 encoders will
set it.

This fixes a segfault when using the C version of ac3dsp.float_to_fixed24().

It was broken in 4:4:4, and still did chroma deblocking for no reason in 4:2:0.

Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

sizeof(SampleType) is different for fixed and float encoders.

Function pointers are used for templated functions instead of needlessly
duplicating many functions.

This will allow the same struct to be used for both the fixed and float ac3
encoders.

functions.

Needs some ARM/PPC asm modifications.

Currently, the parser is buggy and only processes the stream extradata
when the flag is set. This fixes it to actually inspect the frames.

Whitespce will be fixed in a separate change.
