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.
