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).

Sensors: Setting sensor's sensitivity value to default retrieved from fw

Currently, the sensitivity value for sensors are set to DEF_HYST_VALUE
which is set to zero. This causes a continous stream of events even
when the device is still. This patch changes the behavior by initially
reading the default value of the sensor's sensitivity from firmware and
setting it back. If we are unable to read it, then we will set it to 0.

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: correct read() usage

The readEvents() implementation would attempt to read buffer_len (two
by default) IIO events from the device, but would only ever process
one, leading to dropped events in the case of overflow. It was also
not checking the return value from read and would push garbage data on
I/O errors (probably would not happen in regular usage, but IIO
devices are known to return -EBUSY or -EINVAL if there are other users
or if the sysfs parameters are set incorrectly).

once on initialization. The info_array would continually grow with
newly probed channel objects (i.e. 3 objects for

was similarly used to size the raw_buffer used for the read() call.

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.

bigcore: Give more time for iio device detection

Currently android framework checks if /sys/bus/iio/devices node
is created and sets sensor property based on it. The check is
performed in a for loop of ~1 sec.
Looks like for i2c based sensors it is taking more time for the
node to be created and hence setting of property fails.

Increase the loop time to ~5 sec max which gives enough time for
the node to be detected.
