This keeps us from setting the text on a node if it is a SCOPES_ROUTE node, and sends the "TYPE_VIEW_FOCUSED" event when we update the semantics information and a view has the input focus.
This adds an isFocusable to SemanticsFlag so that the framework can tell the engine what semantics nodes are allowed to be focused, which will affect what platform flags are applied to the semantics information.
This flag is not yet in use by the frame
This change modifies the accessibility bridge so that if a node has input focus, then it will tell TalkBack so that it will request the accessibility focus for the view.
It also sets the content change types bit field to include CONTENT_CHANGE_TYPE_SUBTREE to indicate that the subtree for the view has changed for API levels after, and including, KitKat (19)
Prevents NPEs and simplifies the code needed to handle these collections. There doesn't seem to have been a meaningful difference between null and empty collection here. The specific crash was happening when `object.scrollChildren > 0` while `object.childrenInHitTestOrder == null`, which looks like it may be a bug on its own and probably needs further investigation.
