e6e9823488 Add apply_window_int16() to DSPContext with x86-optimized versions and use it
in the ac3_fixed encoder.

0aded9484d Move dct and rdft definitions to separate files
This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.

0f999cfddb ac3enc: add float_to_fixed24() with x86-optimized versions to AC3DSPContext
and use in scale_coefficients() for the floating-point AC-3 encoder.

79414257e2 mathops: fix MULL() when the compiler does not inline the function.
If the function is not inlined, an immmediate cannot be used for the
shift parameter, so the %cl register must be used instead in that case.

This fixes compilation for x86-32 using gcc with --disable-optimizations.

aaff3b312e mathops: change "g" constraint to "rm" in x86-32 version of MUL64().
The 1-arg imul instruction cannot take an immediate argument, only a register
or memory argument.

b181b8fb96 mathops: convert MULL/MULH/MUL64 to inline functions rather than macros.
This fixes unexpected name collisions that were occurring with variables
declared within the macros.
It also fixes the fate-acodec-ac3_fixed regression test on x86-32.

17cf7c68ed Fix ff_emu_edge_core_sse() on Win64.
Fix emu_edge_v_extend_15 to be <128 bytes on Win64, by being more strict
on the size of registers and which registers are being used for operations
where multiple are available. This fixes segfaults in emulated_edge()
function calls on Win64.

19fb234e4a H.264: split luma dc idct out and implement MMX/SSE2 versions
About 2.5x the speed.

NOTE: the way that the asm code handles large qmuls is a bit suboptimal.
If x264-style dequant was used (separate shift and qmul values), it might
be possible to get some extra speed.
