Justin Ruggles 6ca23db9cc ac3enc: modify mantissa bit counting to keep bap counts for all values of bap 
instead of just 0 to 4.

This does all the actual bit counting as a final step.

Diego Biurrun 5e528cffcf x86: Add appropriate ifdefs around certain AVX functions. 
nasm versions prior to 2.09 have trouble assembling some of our AVX code.
Protect these sections by preprocessor macros to allow compilation to pass.

Mans Rullgard c4f5c2d6f4 Move some mpegaudio functions to new mpegaudiodsp subsystem 
This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

Oskar Arvidsson 19a0729b4c Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. 
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.

Justin Ruggles 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.
