Add ASensorEventQueue_registerSensor and default error value

ASensorEventQueue_registerSensor is new function created in 2016 but
is never exported at NDK level. In this CL the function signature is
formalized and the function name is added to NDK function export
table. Internal class SensorEventQueue is also changed to adapt.

Default error values are also defined.
