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

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.

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.

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.

NEON version of copyframeyonly, extendframeborders, copy_frame_func were
not working for plane stride < 128 and/or y_width < 128.

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.

Added the ability to create rate-targeted, temporally
scalable, VP8 compatible bitstreams.
The application vp8_scalable_patterns.c demonstrates how
to use this capability. Users can create output bitstreams
containing upto 5 temporally separable streams encoded
as a single VP8 bitstream.

buffer_level in VP8_COMP and starting_buffer_level, optimal_buffer_level
and maximum_buffer_size in VP8_CONFIG changed from int to int64_t
to avoid potential crash issues for larger target bit rates.

Previous entropy probs need to be saved (and restored) only when
current updates are not propagated.
