7ff1a4b10f Add add_pixels4/8() to h264dsp, and remove add_pixels4 from dsputil. 
These functions are mostly H264-specific (the only other user I can
spot is bink), and this allows us to special-case some functionality
for H264. Also remove the 16-bit-coeff with >8bpp versions (unused)
and merge the duplicate 32-bit-coeff for >8bpp (identical).

5fd6d85d17 rnd_avg: fix author attribution 
Reference:
commit 41fda91d09
Author: BERO <bero@geocities.co.jp>
Date:   Wed May 14 17:46:55 2003 +0000

    aligned dsputil (for sh4) patch by (BERO <bero at geocities dot co dot jp>)

    Originally committed as revision 1880 to svn://svn.ffmpeg.org/ffmpeg/trunk

commit 8dbe585641
Author: Oskar Arvidsson <oskar@irock.se>
Date:   Tue Mar 29 17:48:59 2011 +0200

    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.
