Bug 1321418 - 1. Use GekcoBundle events in GeckoApp; r=snorp r=sebastian Switch GeckoApp to using GeckoBundle events everywhere. UI or Gecko events are used if the event requires the UI or Gecko thread, respectively, and background events are used for all other events. There are changes to some other Java classes, such as SnackbarBuilder and GeckoAccessibility, due to the switch to GeckoBundle. For "Snackbar:Show", we need the global EventDispatcher because the event can be sent to both GeckoApp and GeckoPreferences. Howveer, we only want one listener registered at the same time, so we register and unregister in GeckoApp's and GeckoPreferences's onPause and onResume methods. Bug 1321418 - 2. Use appropriate JS EventDispatcher to send GeckoApp events; r=snorp r=sebastian Change JS code that sends events to GeckoApp to use either the global EventDispatcher or the per-window EventDispatcher. "Session:StatePurged" is not used so it's removed. "Gecko:Ready" in geckoview.js is not necessary because it's only used for GeckoApp, so it's removed from geckoview.js. Bug 1321418 - 3. Use GeckoBundle events in BrowserApp; r=snorp r=sebastian Switch BrowserApp to using GeckoBundle events, in a similar vein as GeckoApp. UI or Gecko events are used if the event handlers required UI or Gecko thread, respectively, and background events are used for all other events. Some other Java classes also have to be modified as a result of switching to GeckoBundle. Bug 1321418 - 4. Use global EventDispatcher to send BrowserApp events; r=snorp r=sebastian Change JS code that sends events to BrowserApp to use the global EventDispatcher instead of "Messaging". Bug 1321418 - 5. Update usages of events in tests; r=gbrown Update cases where we use or wait for events in tests.
