Rework thumbnail API to not suffer from IPC failures.
Thumbnails are now requested separately, so we don't exceed the
IPC buffer size limit.
Also implement issue #3349553: Please provide a hook to intercept
fragment-breadcrumb clicks
And maybe fix issue #3439199: Music Notification does not turn on
when app switching out of Music app
