Clarify some comments in the sensor HAL
Step count can reset when android restarts
When calling activate() without calling setDelay() before, use a default rate
Uncalibrated magnetometer should not be low pass filtered
The accelerometer can be used for the geomagnetic rotation vector
When batching call retuns an error, it shouldn't change the state. In particular, it shouldn't change the rate.
batch(timeout=0) must always return success
Wake upon fifo full will never be specified when timeout=0
setDelay is not called when in batch mode
