Changes to the function the redistributes bits from overshoot
or undershoot throughout the rest of the clip to respond more
quickly.

Change-Id: I90f10900cdd82cf2ce1d8da4b6f91eb5934310da

Added a factor based on the bit spend in the last arf group vs the
target to adjust the choice of the active worst quality in subsequent
groups.

Helps clips where previously there was a big overshoot or undershoot
to adapt and get closer to the target rate.

Change-Id: I67034b801679b99024409489a2273ea6fe23b8e6

The use of this value is preventing rate adjustment on clips
or sections that have very little motion but high noise and
this can give rise to some sections with massive overshoot.

Add check for actual split before using the variance of the split.

Change-Id: If0f93248be0b16d17738675d16c90516054dad2b

Replaced vpx_d45_predictor_4x4_ssse3(), vpx_d45_predictor_8x8_ssse3()
and vpx_d207_predictor_4x4_ssse3() with
created vpx_d45_predictor_4x4_sse2(), vpx_d45_predictor_8x8_sse2()
and vpx_d207_predictor_4x4_sse2() respectively.
It's mostly neutral or slightly worse than ssse3 in good cases and
better than ssse3 in the bad cases (but still worse than using the mmx
regs).

Skip intra-mode and some inter-modes (newmv, nearmv, nearestmv) for
golden frame if the variance got from choose_partitioning is very low.
Only for 1 pass real-time CBR mode and bsize >= 32x32, it has ~2.5%
speed up with less than 0.1% PSNR drop for rtc test set. Don't see
visual regression.

Reduce operations and jumps. perf shows CPU time reduced from 1.9% to
1.6% when decoding fdJc1_IBKJA.248.webm on Xeon E5.
Will apply the changes to vp10 after code review.

For non-rd pickmode:
best_pred_sad, computed for NEWMV-last, is only used for
skipping golden non-zero modes. Add condition to avoid this
computation if not used (i.e, if golden nonzero modes are not used).

And remove code for computing best_pred_sad for NEWMV-golden,
since that sad is not used.

No change in behavior; small speed gain (~1%) for svc encodes.

Function level timing test shows about 27% time saving on

Rename vp9_dct_sse2.c to vp9_dct_intrin_sse2.c for vp9 and
rename dct_sse2.c to dct_intrin_sse2.c for vp10 to avoid
duplicate basenames.

Actually vp9_fwht4x4_mmx/sse2() and vp10_fwht4x4_mmx/sse2()
are identical. TODO: They should be unified later if there is
no intention to keep a duplicate.

C does not allow for shifting into the sign bit of a signed
integer, and the two instances here become signed ints via
promotion. Explcitly cast them to unsigned MEM_VALUE_T to
avoid the problem.

Followed the code style of other lpf fuctions.
These 2 functions put 2 rows of data in a single xmm register,
so they have similar but not identical filter operations,
and cannot share the same macros.

Apple's version format specification is strictly checked on app
store submission, even for embedded frameworks:

http://apple.co/1WgelY1

    The build version number should be a string comprised of
    three non-negative, period-separated integers with the
    first integer being greater than zero. The string should
    only contain numeric (0-9) and period (.) characters.

So that's room for "1.5.0" but not for "1.5.0-906-g656f9c41".

The full version returned from 'version.sh --bare' is now
embedded under a 'VPXFullVersion' custom key in the Info.plist,
so it can still be extracted from the resulting framework.
