This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

Preparatory patch for high bit depth h264 decoding support.

This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.

and use in scale_coefficients() for the floating-point AC-3 encoder.

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.

The 1-arg imul instruction cannot take an immediate argument, only a register
or memory argument.

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.

This reverts commit cc4d3dd3.

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.
