e656f44c24 update vp9_thread.[hc] 
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.

68ff368d19 Enable tests using WebM files only if webm_io is enabled 
There are a few tests which read/write directly to/from WebM files. They should
be disabled when --disable-webm-io is passed.

6ae58931d6 Fix decoder resolution change with tiles 
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.

820201caa8 vp9_thread: add vp9_worker_execute()

    add WebPWorkerExecute() for convenient bypass

    This is mainly for re-using the worker structs without using the
    thread.
