Tests showed ~1.2% performance boost on the HD clip used.
Performance will vary based on material.

Update ARM asm implementation of vp8_start_encode to new definition.

Small performance gains.

Interleaved vp8_find_near_mvs and vp8_mv_ref_probs.
2.5% to 4% performance improvement for the HD clips used.

The partial frame copy function used to copy an extra 8 lines above
and  below. The partial frame filtering can only modify 3 pixel rows
above the partial frame. Reduce copy to bare minimum needed, which is
4 lines, so that partial filtering on copied frame is possible.

Define the "magic" fraction number for partial filtering in
loopfilter.h .

Restructure if statement to clarify the error condition. Trigger the
error before clobbering pc-> variables.

Global function pointers can not be defined in header files. Restructure
vpx_scale pointer configuration.

Decode the mv mode with if-then-elses instead of traversing
the vp8_mv_ref_tree data structure.  This will make it
easier to interleave vp8_find_near_mvs and vp8_mv_ref_probs.

Did some cleanup as well.

Patchset 2:  Fixed bug.  Will revisit the segmentation logic.

check to make sure that cx_data buffer has enough room before
writting to it, prior behavior did not which could result in a crash.

During the _pick only the Y plane is examined. In addition, data beyond
the borders of the frame is not read.

Tests showed over 2% improvement on various HD clips.

Instead of using the predict buffer, the decoder now writes
the predictor into the recon buffer.  For blocks with eob=0,
unnecessary idcts can be eliminated.  This gave a performance
boost of ~1.8% for the HD clips used.

Tero: Added needed changes to ARM side and scheduled some
      assembly code to prevent interlocks.

Patch Set 6:  Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3)
into this commit because of similarities in the idct
functions.
Patch Set 7: EC bug fix.

It was crashing when number of partitions was bigger than the number
of MB rows (ex. 128x96 with 8 partitions).
Start point was not checked against mb_rows, plus extra
"empty" partitions were not written out.
