c90b94424c 4:4:4 H.264 decoding support
Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

504811baea Roll back 4:4:4 H.264 for now
Needs some ARM/PPC asm modifications.

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.

2a1f431d38 H.264/SVQ3: make chroma DC work the same way as luma DC
No speed improvement, but necessary for some future stuff.
Also opens up the possibility of asm chroma dc idct/dequant.

bd11c7a1a8 Remove outdated comment in h264dsp.h
Since we no longer have non-transposed scantables, the problem it warns about
no longer exists.

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.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

4693b031a3 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
non-h264 code.
