Talos causes accessibility to be instantiated only in the content
process. That means PDocAccessibleConstructor messages can be recieved
by the parent when GetAccService() returns null. The easiest way of
dealing with this is moving DocManager::mRemoteDocuments from a member
of the acc service singleton to its own global. That means the parent
process can track accessible documents in child processes without
instantiating a11y in the parent process.
This is necessary to have strong guarantees that promises will be resolved.
While we're flushing the task queue, normal dispatch starts to fail,
meaning that we can't dispatch promise resolution. We have 3 options to handle
this:
(A) Never respond to the promise.
(B) Invoke the Resolve/Reject callback synchronously if dispatch fails.
(C) Prevent dispatch from failing.
(C) seems like the option least likely to violate invariants if we can get away
with it. Promise resolution is unlikely to be a heavyweight task in the way that
a decode task might be, so this should hopefully be ok.
Note that this still doesn't help for bonafide task queue shutdown. It's up to
consumers to tear down their MediaPromiseHolders before the task queues are shut
down.
Resolve the build failure caused by API changes
There are some changes in Audio APIs in Android version
21. Modifying the code to use the new APIs.
