ebff73c37d Bug fix for SensorFusion data rate.
SensorFusion is always returning data at the slowest possible sampling rate (5 Hz). batch() is getting called twice, first time with the requested rate and second time with the slowest rate (which overwrites the requested rate). Fix batch call in SensorFusion::activate()

ba02cd2f6c improve sensorservice's dumpsys
it now displays the reported trigger mode properly, as well as
the number and type of the last received data

2e2a560c4b use gyro timestamp directly in fusion
we used to estimate the gyro rate and deduce the period from that
but it turns out this is causing problems.

3301542828 use quaternions instead of MRPs
also use correct time propagation equation
disable the fused sensors when gyro is not present since
they were unusable in practice.
