Input: introduce input_inject_event() function
Create input_inject_event() function which is to be used by input handlers as opposed to input_event() which is reserved for drivers implementing input devices. The difference is that if device is "grabbed" by some process input_inject_event() will ignore events unless sent from the handle that is currently owns the device.
