If a remote devices offers multiple descriptors with the same UUID, the
instance ID is used to differentiate between them.

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

- Add non-blocking write support, set_callback() function
- Add pause, resume, flush, drain functions to audio output stream
- Add audio parameter defines for compressed audio metadata
- Extend audio_config_t to include an audio_offload_info_t field
- Add is_offload_supported() function to test whether there is
hardware decode support for a given compressed audio format
- Change audio_stream_frame_size() to handle offloaded streams.
For an offloaded stream the size is always counted in bytes
(frame size == 1) and the number of channels is irrelevant.

Flush is used to quiesce a camera device as quickly as possible, which
can be used to deal with a pathological client (requests a frame
duration of hours then dying) as well as speed up stream configuration
changes when the outstanding requests data isn't required.

HALs seem to need to know the gralloc usage flags of the opposite
endpoint (producer/consumer) of a stream at configure time.
Instead of adding another call to pass stream information, we just
pass the usage flags in the existing usage field.

Add hints for video encode and decode use cases. These
hints are sent when the relevant use case starts and ends.
Clients can also send metadata along with the hint to provide
context to the power HAL so that it can make more informed
decisions about how to tweak system-level parameters.

Fused location allows for fusion of information from
multiple source like GPS, Wifi, Cell, Bluetooth, Sensors etc
to get a location. Doing this in hardware is useful because
it can be done completely in the baseband without waking up the AP.

This method is meant for locking the flexible YCbCr format documented in

- Clarify ownership of fence file descriptors, including in case of
errors.
- Make it clear notify SHUTTER must be called before the first
process_capture_result.

Allow the HAL to split the capture result across multiple calls to
process_capture_result, so that when the sync framework cannot be
used, some output buffers can still be returned later than others.
