f7bd4a8ebd Cosmetics: rename enc -> dec in opt_input_file(). 
The variable refer to a *decoder* context, the old name was
misleading.

527b46ba26 ffmdec: Do not manually free streams on read_header error, this is always 
handled by upper layers.
Fixes double-frees (issue 2003).
Instead call ffm_close to ensure rc_eqs are freed also in the error case.

e3f7bf774c Fix SPLATB_REG mess. Used to be a if/elseif/elseif/elseif spaghetti, so this 
splits it into small optimization-specific macros which are selected for each
DSP function. The advantage of this approach is that the sse4 functions now
use the ssse3 codepath also without needing an explicit sse4 codepath.

496c645d3b Never shrink the ByteIOContext buffer in ff_rewind_with_probe_data 
If there is little unread data in the ByteIOContext buffer, this may lead
to reducing the size of the ByteIOContext buffer to little more the probe
data size. This can lead to suboptimal aviobuf behaviour, e.g. making some
demuxers fail to do short seeks backwards (if the input isn't seekable).

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.

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

ef38842f0b VP8: smarter prefetching 
Don't prefetch reference frames that were used less than 1/32th of the time so
far in the frame.
This helps speed up to ~2% on videos that, in many frames, make near-zero
(but not entirely zero) use of golden and/or alt-refs.
This is a very common property of videos encoded by libvpx.
