By default, this test runs through a range of application-set
exposure, frame duration, and sensitivity values, and verifies
that the duration of capture, and in some cases the brightness,
match what's expected.
Optionally, it can use environment variables to specify the
burst parameters, and to enable dumping the captured YUV images
to flash for later debugging.

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

The shutter callback timestamp should originate from the sensor itself,
since it knows exactly when the first line of the frame started
exposing. However, as a fallback (or in the CPU-painting case) query
CLOCK_BOOTTIME instead.

Metadata is currently only used for immutable persistent settings
(static camera characteristics, and the capture templates), but will be
used for dynamic metadata as well. Make it deleteable so we can
create/destroy these at will.

max_buffers and usage are read by the framework inside the struct used
to pass the stream configuration parameters; scribble our new
calculated values whever they are updated internally.
Adds logging to stream creation method (reuse/new).

Basic static metadata statically constructed from preprocessor passes
over an array of camera metadata tags.

- 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.
