The denoiser was writing to LAST_FRAME buffer. If LAST_FRAME isn't being
updated, the reference frame buffers were out of sync between the encoder and the
denoised raw buffers. This patch resolves the discrepancy by always writing to a work
buffer (INTRA_FRAME) and then copying from that buffer to any buffers that needs to
be updated.

Multi-threaded code was not updated to disable background
refresh for non base-layer frames at the time it was
disabled in the main C-code.

Don't use the switch to gf_rate_correction factor when
temporal layers is used (i.e., cpi->oxcf.number_of_layers > 1).
In temporal layers, we prefer to avoid this as any frame
(e.g., base layer frame at anchor of pattern) may update
both last and golden (and possibly alt-ref), and so we would get
different rate correction factors within the same layer.
This change will make sure one rate correction factor exists for each layer.
Also, made some other code in qp-regulate that depends on
alt/golden update specific to the 1 layer case.

Creates a merge between the master and experimental branches. Fixes a
number of conflicts in the build system to allow *either* VP8 or VP9
to be built. Specifically either:
$ configure --disable-vp9 $ configure --disable-vp8
--disable-unit-tests
VP9 still exports its symbols and files as VP8, so that will be
resolved in the next commit.
Unit tests are broken in VP9, but this isn't a new issue. They are
fixed upstream on origin/experimental as of this writing, but rebasing
this merge proved difficult, so will tackle that in a second merge
commit.

Most of these were picked up by jenkins in the commit that changed
the vp8 namespace to vp9 in common/.

For non-static functions, change the prefix to vp9_. For static functions,
remove the prefix. Also fix some comments, remove unused code or unused
function prototypes.

Most of these were picked up in the previous commit (prefix change from
vp8_ to vp9_), but I'm pushing this separately so that it's easier to
review.

Converted the forward and inverse transforms to integer forms.
Modify #define TEST_INT 1/0
in the code to call integer/float version of transforms.
The tests showed that average OVERALL PSNR loss was less than 0.1%.

Preparation for project restructuring.
Added vp9_ prefix on some function names that have global scope.
Added static declaration on some that dont.

Previously, in evaluating reference motion vectors, MVs are always
rounded to integer pixel position and SADs are calculated. This
commit takes into account the subpixel portion of the mvs, and uses
bilinear interpolation to produce reference pixel values in subpixel
postions. In addition, SSE is used in place of SAD. Pixels used are
16x2 above and 2x16 to the left.
This commmit intends to test the potential of this line of work in
term of compression improvement, obviously, the change would increase
decoder complexity significantly.

Cleaned up some inconsistent references using both xd-> and
x->e_mbd. to access the same data structure in the same function.

Coding and costing of mv reference signal.
Issues in updating MV ref with COMPANDED_MVREF_THRESH
to be resolved. Ideally the MV precision should be defined based
on absolute MV magnitude not as now the MV ref magnitude.
Update to mv counts moved into bitstream.c because otherwise
if the motion reference is changed at the last minute the encoder
and decoder get out of step in terms of the counts used to update
entropy probs.
Code working on a few test clips but no results yet re benefit vs
signaling cost and no tuning of red loop to test lower cost alternatives
based on the available reference values.
Patch 3. Added check to make sure we don't pick a reference
that would give rise to an uncodeable / out of range residual.
Patch 6-7: Attempt to rebase. OK to submit but best to leave flag off for now.
Patch 9. Remove print no longer needed.

Refactor per-transform copy & paste into a common function
update_coef_probs_common() and read_coef_probs_common(). The dry-run and
bit-writing loops in the encoder are still obvious candidates to be made
common, but they start to diverge a bit in the next commit, so are left
as-is for now.

There is a macro DEFAULT_INTERP_FILTER defined in encoder/onyx_if.c that
is set as EIGHTTAP for now - so SWITCHABLE is not really used. Ideally,
this should be SWITCHABLE but that would make the encoder quite a bit slower.
We will change the default filter to SWITCHABLE once we find a faster way to
search for switchable filters.

Fix another typo in 4x4-transform-for-i8x8-intra-pred coeff contexts.

Use SPLITMV_PARTITIONING instead of a plain integer type.
