3cffa0c74e Move vp9_thread.* to common.
Prepare for frame parallel decoding, the reference count buffers
need to be protected by mutex. Move vp9_thread.* to common
folder so that those buffers could use cross-platform mutex
from vp9_thread.*.

(cherry picked from commit 337e8015c9)

749e0c7b28 Revert "Revert "Revert 3 patches from Hangyu to get Chrome to build:""
This reverts commit b336356198.

This causes a hang in:
VP9/InvalidFileTest.ReturnCode/3

the change to test/user_priv_test.cc remains with a minor update

b336356198 Revert "Revert 3 patches from Hangyu to get Chrome to build:"
This patch reverts the previous revert from Jim and also add a
variable user_priv in the FrameWorker to save the user_priv
passed from the application. In the decoder_get_frame function,
the user_priv will be binded with the img. This change is needed
or it will fail the unit test added here:
https://gerrit.chromium.org/gerrit/#/c/70610/

This reverts commit 9be46e4565.

9bc040859b Introduce FrameWorker for decoding.
When decoding in serial mode, there will be only
one FrameWorker doing decoding. When decoding in
parallel mode, there will be several FrameWorkers
doing decoding in parallel.

ae7d3ef39f Moving loopfilter call to vp9_decode_frame().
Inline loopfilter has been already handled in vp9_decode_frame().
Collecting all similar code in one place now.

As pointed out by Dmitry and James, "partial" is a Microsoft-
specific c++ keyword, and it is renamed.

903801f1ef vp9 decoder: row-based multi-threaded loopfilter
Implemented parallel loopfiltering, which uses existing tile-
decoding threads. Each thread works on one row, and when that row
is loopfiltered, it moves to next unattended row. To ensure the
correct filtering order, threads are synchronized and one
superblock is filtered only if the superblocks it depends on are
filtered already.

To reduce synchronization overhead and speed up the decoder, we use
nsync > 1 for high resolution.

Performance tests:
1. on desktop:
8-tile 4k video using 8 threads, speedup: 70% - 80%
4-tile HD video using 4 threads, speedup: ~35%
2. on mobile device(Nexus 7):
4-tile 1080p video using 4 threads, speedup: 18% - 25%
4-tile 1080p video using 2 threads, speedup: 10% - 15%
