Splits profile 2 into Profile 2 and 3, where profile 2
ony supports 420 sampling, while profile 3 adds 422/444 and
alpha. Keeps room for further expansion.
Also makes some minor changes in the decoder parameters,
replacing --convert-to-8bit with output-bit-depth.

Improves performance on derf by 0.89% for 10-bit internal
and by 0.55% for 12-bit internal, both for 8-bit sources.

The high precision are only used if
configured with --enable-high-transforms
It gives greater precision in the transform.
This gives PSNR improvements when encoding
true 10 and 12 bit streams.
At the moment, the quantizer used is shifted
up by 2/4 for 10/12 bits so that the quantized
coefficients fit in the current token range.

vpxenc now accepts high bitdepth y4m files
vpxdec now produces high bitdepth y4m files
(Only if the bitstream is high bitdepth)
Can force 8bit output via --covert-to-8bit
Change-Id: Ife9fc40772aceed32ba47d7ca81024ed09563721
Refactored code to match current style on master.
Also fixed a bug where some sse results were
not being shifted for high bitdepth.
Also increased internal bitdepth for variance to
avoid saturation.
Also added rounding for variance when computing
shifted results.

Adds a place holder input bit depth parameter. Also
implements the bit-depth parameter and the new paramter
directly using config paramters rather than controls.
That makes it more convenient to handle.

The previous change only tunes forward transform. It doesn't affect
the neon implementation of the inverse transform. Hence turn the
unit test on.

This commit enables the SSSE3 implementation of full inverse 16x16
2D-DCT. The unit runtime goes down from 1642 cycles to 1519 cycles,
about 7% speed-up.

The intepolation filter functions can be better tested withe extreme
values, especially given the optimization functions are prone to
overflow signed 16 bit intermediate value when operation order is
wrong.

Further changes to first pass allocation for gf/arf groups.
Three variables removed from TWO_PASS structure as only
now used locally. Dont adjust gf_group_bits in the post
encode update as this will no longer have any effect.

In 8-tap filtering, to guarantee the intermediate results fit in
16 bits, the order of accumulating the products needs to be done
correctly, and the largest product should be added last. This
patch fixed the problem using the method in commit "Correct ssse3
8/16-pixel wide sub-pixel filter calculation".
Change-Id: I79d0ad60c057b15011ece84cda9648eee0809423
Restructuring to allocate the bits for each frame in
a GF group at the time the group is defined.
At the moment the allocation closely mirrors what
we had before.
Also changes the default rate adjustment method to
LONG_TERM_VBR_CORRECTION.

Fixes a bug introduced in
https://gerrit.chromium.org/gerrit/#/c/69779/13, where
uninitialized frame buffers due to corrupt and short
buffer sizes, may cause a crash.
This patch fixes the currently failing

As mismatchs were found between the intrinsic version and c only. The
commit temporarily revert to use the matching assembly version to
allow further investigation.

Use the appropriate subblock offset mode info rather than the parent
block base, when filling mbmi in the pc tree in nonrd_use_partition.
This mimics what is done in the vertical case and what is done for
both cases in nonrd_pick_partition.
This change has little practical effect at the moment since in speed 5
rt horizontal and vertical partitions are currently only used unpaired
at edges of the picture.
