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>[_

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

dsputil_mmx.c: remove ff_vector128.

Remove ff_vector128, it is identical to ff_pb_80.

Separate format conversion DSP functions from DSPContext.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

x86: remove VLA in ac3_downmix_sse

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....

In yadif filter, declare asm constants directly to avoid dependency on libavcodec

dsputil_mmx: add xmm registers to clobber list

Originally committed as revision 25611 to svn://svn.ffmpeg.org/ffmpeg/trunk

MMX, MMX2, SSE2 and SSSE3 optimizations for pred16x16/8x8_plane H264 intra
prediction (plus some with different rounding for svq3/rv40). Speedup (for
SSSE3) about ~6-fold, 3.6% faster overall with cathedral sample.

Move H264 dsputil functions into their own struct

This moves the H264-specific functions from DSPContext to the new
H264DSPContext. The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by...
