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.

Uninitialized data could be written to the first pass file when no
motion vectors are present in the frame.
Also fix a number of compiler warnings.

The data processed by the loopfilter overlaps. At the block level, this
results in some redundant transforms. Grouping the filtering allows for
a single 16x16 transpose (and inversion) instead of three 16x8 transposes
(and three more inversions).
This implementation is x86_64 only. We retain the previous
implementation for x86.
Improvements are obviously material dependant, but it seems to be ~%1 in
tests here.

vp8_find_near_mvs() is being called on all possible reference frames
but the data computed may be used if the loop exits early, which can
be due to x->skip beign set to 1.
Optimize this by call vp8_find_near_mvs() laziy only if it is going
to be used and not computed yet.

Changes to the selection of Q limits for two pass
and two pass CQ mode.
Allowance made for Mode and motion vector costs.
Some refactoring of common code.
For Derf and YT sets CQ mode average improvement
circa 1% (SSIM and Global PSNR).
Some increased tendency to undershoot even when
user CQ not reached.
Patch2: Removed some test code accidentally merged.

'all' is the conventional target for building everything in the
makefile, but the child make was expecting all-$(target), for debugging
reasons that I don't recall exactly. Restore the expected behavior.

Sync with loopfilter thread just at the beginning of next frame encoding.
This returns control to application faster and allows a better multicore scaling.
When PSNR packets are generated the final filtered frame is needed imediatly
so we cannot delay the sync.
