Per the product discussion, the Notification API should be disabled in
ServiceWorker in release builds for 42 since the UX isn't great [1].
The aim is to release in 44.
Apologies for the code duplication for pref checking in Notification and
ServiceWorkerRegistration. There isn't a easy way to get
ServiceWorkerRegistration's generated binding to include Notification.h without
having an attribute/method that uses Notification.

Get rid of having users dispatch control runnables. It was error prone and
required too much reasoning. It was also possible to end up in a state where
callers would dispatch a WorkerRunnable, which would succeed, so they would not
dispatch a WorkerControlRunnable. Then the worker would stop Running,
canceling and releasing the runnable leading to releasing the proxy in an
unclean state. Instead, we AddRef() and add the feature and remove the feature
and Release() on Notify(). If callers successfully run a WorkerRunnable they
clean the proxy. If not, the proxy stays alive until the worker switches to
Canceling state.
When we use the XUL based alerts and the main firefox window is closed, the XUL
window still keeps the process running, but as the window closes it calls
DisconnectFromOwner() on the Notification. Later, when the XUL alert closes
(either due to timeout or due to script) attempts to get the principal can
fail. This patch allows that to happen and will just skip deleting the
Notification from persistent storage.
Rather than store a non-thread-safe refcounted nsIStructuredCloneContainer, store the base64 representation.
Caches a jsval the first time an attempt to access data is made from content script.
Refactor creation and show dispatch so Notification constructor and showNotification can use it.
Move persistence to ShowInternal.
NotificationStorage calls callback async even when fetching from cache, simply to have similar semantics.
Calls to Notification::Get() are performed async since persistence is now async after being moved to ShowInternal().
Both are in accordance with the spec where the "append to list of notifications" operation is performed in the "show steps" which are performed in parallel from API invocations.
