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.

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.

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

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.

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().

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

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