0319306670b0344da99efa606b6f172dde575a39 11-May-2013 Mathias Agopian <mathias@google.com> various fixes to the sensorservice

1) "google" sensors are now reporting AOSP as the vendor string
2) don't expose the system's sensor fusion if the HAL provides it
3) use uncalibrated gyro if availble for the system's sensor fusion

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

Add support for 9-axis gravity and linear-acceleration sensors
virtual orientation sensor using 9-axis fusion

The cut-off frequency of the lowpass filter was too high
for the sampling rate used by DELAY_NORMAL.

Now we use the same filters used for the gravity vector
(cascaded biquad at 1.5 Hz)

whether a physical sensor needed to be active or not was managed by
a simpe reference counter; unfortunatelly nothing prevented it to
get out of sync if a sensor was disabled more than once.

sensorservice already maintainted a list of all the "clients"
connected to a physical sensor; we now use that list to determine if
a sensor should be enabled. This can never be "out-of-sync" since
this is the only data structure linking a sensor to a user of that
sensor.

also removed the isEnabled() method, which was never used and
implemented wrongly (since it didn't take into account that a sensor
could be disabled for a client but not of another).

ddf1ceb647d029febfd007b389cd92c84668a03c 23-Nov-2010 Mathias Agopian <mathias@google.com> allow rotation-vector to have 4 components

- upadte documentation for rotation vector
- update method dealing with rotation vector to deal with 4 components
- virtual rotation-vector sensor reports all four components
- improve SensorManager documentation layout

Whent he 4-th component of the rotation-vector is present, we can save
a square-root when computing the quaternion or rotation matrix from it.

5c6d7ff3e643d0fb4b46d81a3a4e6edaba779edd 22-Nov-2010 Mathias Agopian <mathias@google.com> don't attempt to normalize the rotation vector

indeed, by construction of the rotation matrix, it is
guaranteed to have a length of 1.

moreover, the normalization code was missing a square-root,
fortunatelly, since the length is 1, this didn't cause any
damage (since sqrt(1) = 1).

f001c92436b4a66eb7687286325ced7f10c9f917 12-Nov-2010 Mathias Agopian <mathias@google.com> Add support for virtual sensors.

Rework sensorservice to allow "virtual sensors", that is
sensors that report a synthetized value based on real sensors.

the main change to sensorservice is around managing which real
sensor need to be activated and which rate to use.

The logic for all this has been moved into SensorDevice, which
essentially wraps the sensor HAL but adds two features to it:
- it keeps track of which sensors need to be activated
- it keeps track of what rate needs to be used

For this purpose an "identity" is associated with each real sensor
activation, so we can track them.

On start-up we check for gravity, linear-acceleration and
rotation-vector sensors, if they're not present in the HAL, we
synthetize them in sensor-service.
