This was done to support gcc 2.95, which is an old legacy compiler
that fails to compile the current codebase anyway.

Needs some ARM/PPC asm modifications.

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.

Remove ff_vector128, it is identical to ff_pb_80.

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

This macro has unconditionally used .p2align for a long time and
serves no useful purpose.

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.
