WIP: Fixing unsafe threading in VP8 encoder.
Use the passed in macroblock instead of the macroblock located in
cpi.
Change-Id: I1bfa07de6ea463f2baeaae1bae5d950691bc4afc
The loopfilter thread from the previous frame can be running while
starting the current frame. cpi->Source will change during this time causing
the wrong data to be copied. The refresh_x_frame flags also change, which
will cause incorrect updates of the denoised buffers.
Change-Id: I7d982b4fcb40a0610801332aa85f3b792c64e4c3
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%.
