Make InputApplicationInfo as a part of InputApplicationHandle (1/2)
InputWindowHandle::updateInfo would also call
InputApplicationHandle::updateInfo that may access the null pointer if the
focus application changed in same time.
- To replace allocated mInfo in updateInfo(), make it as an object
member variable of InputApplicationHandle.
