Just some cosmetics & comments, the only functional change
"error_resilience: use s->last_picture for accessing last MVs."
Is so buggy that it needs a full rewrite, guess -1.0 PSNR loss wasnt
enough for ronald to realize there was a problem.

Help debugging, safer.

Add link to official specifications, remove author duplication and
others.

Remove one level of indirection, simplify code.

Remove one level of indirection/improve readability.

Also rename variable "extradata" to "palette" ff_cmap_read_palette()
and extract_header(), more meaningful.

Remove the problematic av_dlog() call

This breaks API and ABI.

Should fix compile on systems missing yasm/nasm.

Fixes issue 2679.

This patch completes the high bit depth h264 decoding support.

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.

In high bit depth, the QP values may now be up to (51 + 6*(bit_depth-8)).

In high bit depth the pixels will not be stored in uint8_t like in the
normal case, but in uint16_t. The pixel size is thus 1 in normal bit
depth and 2 in high bit depth.

The low quality mode is off by default and never tested.  The high
quality mode is also plenty fast enough.

This fake option cannot be enabled by normal means, and the
floating-point decoder should provide the higher quality this
option presumably was intended for.

Instead use the function pointers directly.

When the file to decode contains a sequence of binary values like
"1101110...", decode_frame() was reading the sequence of digits like a
unique integer value, which was resulting in integer overflows.

The change add support for parsing non-space-separated pixel digits
for mono formats, in particular fix decoding of file battrace.pbm, and
fix trac issue #154.
