The CameraHalManager starts the libcamera CameraManager and creates
CameraProxy instances for each camera in the system. Clean up those
resources when the CameraHalManager terminates.

The CameraHalManager::close() method isn't used, remove it.

The CameraHalManager starts a thread that is never stopped. This leads
to the thread being destroyed while running, which causes a crash. Fix
this by stopping the thread and waiting for it to finish in the
destructor of the CameraHalManager.

The CameraHalManager::getCameraInfo() validates the camera id it
receives from the camera service, and in doing so generates a compiler
error with gcc as the id is an unsigned integer and can never be
negative:
../src/android/camera_hal_manager.cpp: In member function ‘CameraProxy* CameraHalManager::open(unsigned int, const hw_module_t*)’:
../src/android/camera_hal_manager.cpp:89:9: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
if (id < 0 || id >= numCameras()) {
Fix it by removing the unneeded comparison.

The CameraHalManager::getCameraInfo() validates the camera id it
receives from the camera service, and in doing so compares it with an
unsigned integer, generating a compiler error:
src/android/camera_hal_manager.cpp:121:9: error: comparison of integers of different signs: 'int' and 'unsigned int' [-Werror,-Wsign-compare]
if (id >= numCameras() || id < 0) {
~~ ^ ~~~~~~~~~~~~
Fix this by turning the id into an unsigned int, as camera ids can't be
negative. If a negative id is received from the camera service it will
be converted to a large unsigned integer that will fail the comparison
with numCameras().

Add libcamera Android Camera HALv3 implementation.
The initial camera HAL implementation supports the LIMITED hardware
level and uses statically defined metadata and camera characteristics.
Add a build option named 'android' and adjust the build system to
selectively compile the Android camera HAL and link it against the
required Android libraries.
