AOSP Music app: Handle audio VIEW and PICK

Let Music app be the default AOSP intent handler for
 - android.intent.action.PICK for vnd.android.cursor.dir/audio
 - android.intent.action.VIEW for mimeType audio/* and ogg/x-ogg
In TrackBrowserActivity, use intent.getParcelableExtra() to prevent NPE
In MediaPlaybackActivity, add null check to prevent NPE
