* Only notify the event loop if stream buffer is at or above its trigger level
* Reformat comments
* Add event loop stream buffer example application
* Add event loop multiple elements example application
* Improve event loop flag names
* Remove redundant signal handler as it is already handled by the event loop
* Refactor Power service, improve ViewHolder
* Use ViewHolder instead of ViewDispatcher in About app
* Enable ViewDispatcher queue on construction, deprecate view_dispatcher_enable_queue()
* Remove all invocations of view_dispatcher_enable_queue()
* Remove app-scened-template
* Remove missing library from target.json
* Port Accessor app to ViewHolder
