Use ptrdiff_t instead of int for intra pred "stride" function parameter.
This way, SIMD-optimized functions don't have to sign-extend their
stride argument manually to be able to do pointer arithmetic.

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.
