/**
* We would like to expose PushManager and PushSubscription on window and
* workers. Parts of the Push API is implemented in JS out of necessity due to:
* 1) Using frame message managers, in which
* nsIMessageListener::receiveMessage() must be in JS.
* 2) It is easier to use certain APIs like the permission prompt and Promises
* from JS.
* PushManager and PushSubscription are exposed on the main and worker threads.
* The main thread version is implemented in Push.js. The JS implementation
* makes it easier to use certain APIs like the permission prompt and Promises.
*
* Unfortunately, JS-implemented WebIDL is not supported off the main thread. To
* aid in fixing this, the nsIPushClient is introduced which deals with part (1)
* above. Part (2) is handled by PushManagerImpl on the main thread. PushManager
* wraps this in C++ since our bindings code cannot accomodate "JS-implemented
* on the main thread, C++ on the worker" bindings. PushManager simply forwards
* the calls to the JS component.
* Unfortunately, JS-implemented WebIDL is not supported off the main thread.
* To work around this, we use a chain of runnables to query the JS-implemented
* nsIPushService component for subscription information, and return the
* results to the worker. We don't have to deal with permission prompts, since
* we just reject calls if the principal does not have permission.
*
* On the worker threads, we don't have to deal with permission prompts, instead
* we just reject calls if the principal does not have permission. On workers
* WorkerPushManager dispatches runnables to the main thread which directly call
* nsIPushClient.
* On the main thread, PushManager wraps a JS-implemented PushManagerImpl
* instance. The C++ wrapper is necessary because our bindings code cannot
* accomodate "JS-implemented on the main thread, C++ on the worker" bindings.
*
* PushSubscription is in C++ on both threads since it isn't particularly
* verbose to implement in C++ compared to JS.
