libsensors: workaround sensors never detected

Sometimes the iio:devices may not be ready at booting.
Assume it's always present. If you want to detect it
at runtime, set persist.sys.sensors.iio.present=0.

Fix the building issues on Android 6.0

The stlport is gone.

Merge remote-tracking branch 'x86/kitkat-x86' into lollipop-x86

libsensors: make the implementation be compatible with new IIO ABI

Also improve debug messages.

libsensors: fix building issues on Android 5.0

More fields are added to struct sensor_t.

Convert LOCAL_MODULE_PATH to LOCAL_MODULE_RELATIVE_PATH
to support 64-bit targets.

libsensors: Add Android.mk of Android-x86

libsensors: Fix accel and gyro min delay

An earlier commit "https://aia-review.intel.com/#/c/4829/"
set the min delay to 100000 which limited the polling
frequency for gyro and accel (from 100+Hz to ~10Hz).
Setting it to 10000 fixes the issues and handles the
original problem as well (too many events).

libsensors: Integrate the quaternion sensor and use for compass

The sensor hub has a built-in integrated sensor integration scheme
which emits a unified quaternion orientation.  Use this in lieu of
Google's SensorFusion software implementation.

Also: the sensor hub magnetometer emits uncalibrated data because of
requirements on other platforms, but Android demands calibrated
numbers.  Instead of doing magnetometer calibration in the HAL, use
the orientation output to derive a faked "magenetometer" which always
points to magnetic north along the ground plane.  Call this a "leveled
compass".  This behavior is apparently kosher: future (JB 4.3+) API
versions separate the existing "calibrated" compass output from a new
"raw" one which matches the sensor hub behavior.

Finally, the leveled compass implementation requires a little rework
to the SensorIIODev class to allow for reference counting of the
stream (so that it can be active when the sensor itself is disabled).

libsensors: Re-fix "non-streaming" state, provide for rate clamping

This has been fixed, rebroken and re-fixed several times now.  Here's
the deal as I understand it: HID sensors are inherently
"non-streaming" in the Android sense.  They are never guaranteed to
report events at a fixed rate (the IIO sampling_frequency property is
a command to the sensor hub which is doing filtering; some hubs send
fixed rate events, some don't).  The Android API documentation
specifies that this should be signaled by setting the minDelay of the
sensor_t to zero.

But if you do this, then the framework and apps don't know what values
are valid and will attempt to set improbabable values (e.g. 1000Hz).
Sadly the IIO driver will eject those settings instead of clamping
them to a valid range, and the result is that the sensors retain their
default values (e.g. 5Hz for compass in the linked Jira) and look very
slow.

So implement rate clamping in SensorIIODev: subclasses can set their
own minimum delay values to which the HAL will clamp before being sent
the the hardware.  These are populated currently with values specific
to (and empirically determined from) the Intel sensor hub on the
Harris Beach Ultrabook.  Future work will need to make this settable
via configuration.

Sensor HAL: IIO

Implemented IIO based interface for sensors. This adds basic infrastructure
to parse IIO configuration and channels.
Since it is implemented for PnP devices, device can be enumerated
much later than the init process completion and also devices can
be removed during suspend causing stale handles and ownership issues.
