Jim Chen bfe19431c6 Bug 1305498 - Refactor notification code to be more concise; r=sebastian
Bug 1305498 - 1. Remove NotificationClient task queue; r=sebastian

Not sure why we needed a task queue for NotificationClient actions. The
actions all go through IPC and are non-blocking, so it's perfectly fine
to perform them off of whatever thread we're on.

Bug 1305498 - 2. Integrate NotificationHandler et al into NotificationCllient; r=sebastian

There's no reason to have NotificationHandler, AppNotificationClient,
and ServiceNotificationClient all separate from the base
NotificationClient class. This patch adds the functionality of
those three classes to NotificationClient.

The notifications hash map is changed from a ConcurrentHashMap to a
regular HashMap with synchronization because I think the use case here
doesn't warrant the added performance and overhead of ConcurrentHashMap.

NotificationService is changed to match the new NotificationClient. Now
the only job for NotificationService is to set a notification as
foreground, rather than to manage all notifications like before.

NotificationHandler, AppNotificationClient, and
ServiceNotificationClient will be removed in a later patch.

Bug 1305498 - 3. Set NotificationListener in GeckoApplication; r=sebastian

Set NotificationListener once in GeckoApplication.onCreate, instead of
spreading it out in GeckoApp, BrowserApp, and GeckoService. This is
possible because there's no longer a distinction between
AppNotificationClient and ServiceNotificationClient in the new,
consolidated NotificationClient.

Bug 1305498 - 4. Remove obsolete notification classes; r=sebastian

Remove AppNotificationClient, ServiceNotificationClient, and
NotificationHandler, now that they've all been replaced by the new,
consolidated NotificationClient.

Bug 1305498 - 5. Use NotificationReceiver for web notification callbacks; r=sebastian

Previously, web notification callbacks went to GeckoApp directly, but
that presented some problems such as not being able to implement the
on-close callback, because we don't want to launch GeckoApp when the
notification is closed by swiping. This patch makes us use
NotificationReceiver for callbacks, and let NotificationReceiver launch
GeckoApp if necessary.

Bug 1305498 - 6. Don't keep notification cookie in native code; r=sebastian

Keep the notification cookie a single location (in the notification
intent itself), and simplify the native notification handling code.

Bug 1305498 - 7. Use NotificationReceiver for persistent notifications; r=sebastian

Currently, persistent notification callbacks go through a different code
path, but it'd be more consistent and correct to let persistent
notification callbacks go through NotificationReceiver as well.

This takes care of some housekeeping work that was missing for
persistent notifications, such as deleting the mNotifications entry when
the notification is closed.
