ae264bb29b ac3enc: Add channel coupling support for the fixed-point AC-3 encoder.
Update FATE references accordingly.

a0d17b6d45 ac3enc: scale floating-point coupling channel coefficients in
scale_coefficients() rather than in apply_channel_coupling()

3e5722a8ca ac3enc: fix encoding of stereo ac3 files when rematrixing is disabled.
The number of rematrixing bands still needs to be calculated.

069083a419 ac3enc: clip coupling coordinates during calculation
This is faster than using the clip_coefficients() function. Also,
clipping the coordinates before determining reuse is better since it
will compare coordinates that are closer to their final encoded values.

c3d63262fe ac3enc: allow new coupling coordinates to be sent independently for each
channel.

d55ad59a8a ac3enc: separate exponent bit counting from exponent grouping.
Move bit counting to the bit allocation function. Move exponent grouping to
after bit allocation. This will allow for adjustment of bandwidth parameters
during bit allocation without having to do exponent grouping multiple times.

b5849f7709 ac3enc: merge AC3MDCTContext with AC3EncodeContext.
Since both the fixed-point and floating-point encoders use the FFTContext,
this no longer needs to be in a separate context. Also, when a short-transform
context is added, the same MDCT window will be used.

523b7eba19 ac3enc: clip coefficients after MDCT.
This ensures that any processing between the MDCT and exponent extraction will
be using clipped coefficients.

8683c6a638 ac3enc: move ff_ac3_encode_frame() to ac3enc_template.c
This avoids using function pointers for quite a few small functions, most of
which just call DSP functions.

b203f65451 ac3enc: use correct alignment and length in channel coupling dsp functions.
This fixes a segfault when using the C version of ac3dsp.float_to_fixed24().

99477adc31 ac3enc: fix allocation of floating point samples.
sizeof(SampleType) is different for fixed and float encoders.

e0cc66df61 ac3enc: split templated float vs. fixed functions into a separate file.
Function pointers are used for templated functions instead of needlessly
duplicating many functions.
