Add synchronous transaction to wait for setInputWindow to complete (3/n)
Added callback for InputDispatcher to report back to SF.
Pass in an interface callback to setInputWindows so InputDispatcher can send
a response when setInputWindows has completed. The callback can be null
so InputDispatcher knows not to send a response on every setInputWindows
call.
