b3b7645 vp9_dthread: remove frame_parallel_decoding_mode requirement
Change-Id: Ia5a752db9be937153cf4830d9258752136356d1b
This commit moves the primitive multi-threading files from vp9
folder to vpx_thread, which will be accessible by all vpx codec.

thread: remove harmless race on status_ in End()
if a thread was still doing work when End() was called there'd be a race
on worker->status_. in these cases, however, the specific value is
meaningless as it would be >= OK and the thread would have been shut
down properly, but we'll check 'impl_' instead to avoid any potential
TSan/DRD reports.

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.*.

pull the latest from WebP, which adds a worker interface abstraction
allowing an application to override init/reset/sync/launch/execute/end
this has the side effect of removing a harmless, but annoying, TSan
warning.

- camelcase functions -> lower with _'s
- associate '*' with the variable, not the type

There are a few tests which read/write directly to/from WebM files. They should
be disabled when --disable-webm-io is passed.

There was a bug with the decoder that if you started the decoder
with more threads than the first frame had tile columns. Afterwards
tried to decode a frame with more tile columns than the first frame,
the decoder would hang. E.g. run vpxdec --threads=4. The first frame
had two tile columns, then the next key frame had 4 tile columns, the
decoder would hang. If you started with 4 tiles and switched to 2
tiles the decoder would be fine. The issue is that the worker the thread
loop is using is stale.
I added a test vector "vp90-2-14-resize-848x480-1280x720.webm" that
exhibited the bug.

add WebPWorkerExecute() for convenient bypass
This is mainly for re-using the worker structs without using the
thread.

Currently the only threaded option for vp9 decode. Enabled when the
decoder config thread count is > 1.
