Ronald S. Bultje cb7ecb7563 vp56: Use hpeldsp instead of dsputil for half-pel functions
This makes vp5 and vp6 independent of dsputil.

Ronald S. Bultje 015821229f vp3: Use full transpose for all IDCTs
This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.

Also remove the unused type == 0 cases from the plain C version
of the idct.

Ronald S. Bultje d85c9b036e vp3/x86: use full transpose for all IDCTs.
This way, the special IDCT permutations are no longer needed. Bfin code
is disabled until someone updates it. This is similar to how H264 does
it, and removes the dsputil dependency imposed by the scantable code.

Ben Jackson 39a3894ad5 lavc/vp6: Implement "slice" threading for VP6A decode
The YUV channels of VP6 are encoded in a highly linear fashion which does
not have any slice-like concept to thread.  The alpha channel of VP6A is
fairly independent of the YUV and comprises 40% of the work.  This patch
uses the THREAD_SLICE capability to split the YUV and A decodes into
separate threads.

Two bugs are fixed by splitting YUV and alpha state:
- qscale_table from VP6A decode was for alpha channel instead of YUV
- alpha channel filtering settings were overwritten by YUV header parse

  g722enc: validate AVCodecContext.trellis
  g722enc: set frame_size, and also handle an odd number of input samples
  g722enc: split encoding into separate functions for trellis vs. no trellis
  mpegaudiodec: Use clearer pointer math

Jason Garrett-Glaser 05c04cdf54 VP5/6/8: ~7% faster arithmetic decoding
Grab from the bitstream in 16-bit chunks instead of 8-bit chunks.

Always inline the arithmetic coder, except in the case of header-parsing stuff,
in which case don't inline it at all to save code size.

Eli Friedman 3611e7a309 Inline asm for VP56 arith coder
This is a lot more reliable to get cmov rather than trying to trick gcc into
generating it, useful since it's 2% faster overall.

David Conrad fe1b5d974a Decode DCT tokens by branching to a different code path for each branch
on the huffman tree, instead of traversing the tree in a while loop.

Based on the similar optimization in libvpx's detokenize.c

10% faster at normal bitrates, and 30% faster for high-bitrate intra-only
