Utiltizes ARC++ image processing code to perform the conversion between
the camera format and the requested format from the framework. In order
to support USB devices which may not implement the required formats,
conversion between YUYV/MJPEG to the request format is done on-the-fly.
TEST: All existing unit tests pass. Tested manually with the camera
sample APK, preview/video/capture in both JPEG and YUV formats. Tested
on the RPi v2 Camera, the Logitech C270 and the 180 degree Fisheye USB
camera.

Both in_flight_lock_ lock in v4l2_camera.cpp and buffer_queue_lock_ in
v4l2_wrapper.cpp have problems that guards the buffer indices and in
flight buffer vector incorrectly. Those problem leads to mismatching in
terms of buffer size between the HAL and Camera3Device and eventually
the Camera3Device will stop to wait for buffers that HAL will not post
in the future.
Bug: 69076261
Test: Camera samples app doesn't stuck with FB impl.
Exempt-From-Owner-Approval: got +2 from the HAL maintainer.

The reference implementation stream validation/setting
was all out of whack, particularly the handling of "reuse"
streams. This CL does away with that, and plugs in the
static_properties/request_tracker validation/tracking of
configured streams.
Implementation specific features, such as gralloc flags,
are moved down into the V4L2Camera class out of the Camera class.
BUG: https://b/33057320, https://b/31044638
TEST: unit tests pass, some previously failing CTS tests are passing
(and no regressions), simple test camera preview app runs.

Camera now has special synchronized threads to enqueue
buffers and dequeue buffers.

Set up a series of methods that can be producers/consumers/callbacks.
For now, they call each other synchronously.

Replaces metadata usage in Camera/V4L2Camera with the
new Metadata class.
Switches Camera from camera_metadata_t to android::CameraMetadata
where appropriate for ease of use/clarity of ownership.
Also cleaned up some "error" logs that were potentially expected,
leaving it to the caller to log if something goes wrong, since
they were numerous and cluttering the log feed.
BUG: https://b/30140438, https://b/29335262
TEST: unit tests pass, test picture program still works,
tested setting a V4L2 control to a non-default value.

Query formats, sizes, and frame rates.
BUG: https://b/29394024, https://b/30605346
TEST: Test java program shows a bunch of formats & rates,
can take pictures in different sizes now.
