Repaces them with just doing the error check,
and a loop for available characteristic keys.

As part of this, refactored characteristic initialization into its own
function so it can be used by both templates and static info.

Fills in initial values for all required static info
fields for LIMITED devices. Currently fakes entries
that will eventually be queried from the device (open
bug https://b/29394024).

Since V4L2CameraHAL now populates its list of cameras,
also added a necessary piece of metadata that was
causing cameraservice to crash.
BUG: 29160300
TEST: Ran on rpi3. HAL finds dev/video* nodes. When a
sym link (/dev/video5 -> /dev/video0) was added, the HAL
correctly did not add a 3rd device.

Decent outline of an initial HALv3. Still a lot to be filled in.
Adapted from the reference implementation in libhardware.
BUG: 29006356
TEST: Ran simple test program. Connects to the HAL and then
fails because there are no cameras (expected behavior right now).

The Metadata module segfaults when asked to initialize camera_info, upon
camera description request coming from framework.
This was caused by missing intialization of mData instance field.
Additionally, when intializing it with a template metadata, the
validation function return value was wrongly tested
Patchset 2: Do not init mData but let function flow take care of
replacing it after adding new data to it fails.

steps after the library is loaded.

- Deprecates vendor tag specification in camera3 device.
- Moves vendor tag ops declaration to camera metadata library and
cleans up definitions.
- Updates the example HAL.

Add* functions const to protect data being added.
Initiailze metadata object from a camera_metadata_t.
Remove template-specific constructor.
Add convenience "add1" method to abvoid stack-allocated data.
Construct templates manually (in ExampleCamera) from base.

ExampleCamera represents a specific (e.g. front or back) camera device,
and contains all the device and logic for that device/sensor.

Now that libutils is outside of frameworks, use that for c++-style
scoped tracing and remove the temporary shim header.

Static camera characteristics can be queried on any device at any time.
Separate the locking for it from the rest of the device to eliminate any
contention between operations on the device and static characteristic
initialization.

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.

Adds a Stream object, and configureStreams support in parsing the
provided stream_array. Streams are naively setup for sync-less software
painting.

This c++ helper class is normally provided by frameworks/native's
libutils, but cannot be used from the context of a hardware module. For
now just add the required functionality locally in the hardware module.

Refactor the camera module into a single CameraHAL object. Adds
set_callbacks, new in the v2.1 module API.

Explicitly hide all symbols from being exported from the camera HAL
except the symbol required to load the module.

This is meant to be an example and a reference for device manufacturers
on how to build a new Camera v2 HAL. This first patch has basic
configuration and entry/exit.
