This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.

This is never used.

It does not help as an abstraction and adds dsputil dependencies.

This feature is complex, of questionable utility, and slows down
normal decoding.

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.

I've left out the idctCol2 part, because W4 has recently been decreed
to be 16383, and also I doubt it will give a noticeable speedup.
