b9a7186bf4 VP8: Don't store segment in macroblock struct anymore.
Not necessary with the previous patch.

c55e0d34ba Convert VP8 macroblock structures to a ring buffer.
Uses a slightly nonintuitive ring buffer size of (width+height*2) to simplify
addressing logic.
Also split out the segmentation map to a separate structure, necessary to
implement the ring buffer.

968570d65f Calculate deblock strength per-MB instead of per-row
Gives better cache locality, since the VP8Macroblock structs are still in cache.
Inspired by the way x264 does it.

d1c58fce20 Avoid tracking i4x4 modes in P-frames in VP8
As in the previous commit, they aren't used for context selection, so it saves
memory this way.

158e062c95 Avoid useless fill_rectangle in P-frames in VP8
In VP8, i4x4 only uses contexts based on neighbors in I-frames.

c0498b3031 Take shortcuts for mv0 case in VP8 MC
Avoid edge emulation -- it isn't needed if there isn't any subpel.

d864dee8ab Add prefetching to VP8 decoder
~5% faster overall, probably depends on CPU and resolution.

070ce7efad vp8: add do { } while(0) around XCHG() macro to avoid confusing if/else
This is the correct solution to the warning "fixed" in the previous
commit.

3facfc99da Change function prototypes for width=8 inner and mbedge loopfilter functions
so that it does both U and V planes at the same time. This will have speed
advantages when using SSE2 (or higher) optimizations, since we can do both
the U and V rows together in a single xmm register.

This also renames filter16 to filter16y and filter8 to filter8uv so that it's
more obvious what each function is used for.

7ed06b2be8 Simplify MV parsing, removes laying out 2 or 4 (16x8/8x8/8x16) MVs over all
16 subblocks (since we no longer need that), which should also lead to a
minor speedup.

7c4dcf8165 Optimize split MC, so we don't always do 4x4 blocks of 4x4pixels each, but
we apply them as 16x8/8x16/8x8 subblocks where possible. Since this allows
us to use width=8/16 instead of width=4 MC functions, we can now take more
advantage of SSE2/SSSE3 optimizations, leading to a total speedup for splitMV
filter of about 10%.

d6f8476be4 Make VP8 DSP functions take two strides
This isn't useful for the C functions, but will allow re-using H and V functions
for HV functions without adding separate H and V wrappers.
