Because callbacks are called from a looper thread, if the subscriber
unsubscribes and frees the callback, invalid memory access may occur from the
looper thread.
Address this by draining all pending callbacks at the time of listener
unregistration.
NOTE: There is rare chance that the wait on the condition times out,
still resulting in the original NPE issue. We intensionally allow that
to avoid deadlock, in case the application uses the same mutex lock for
callbacks and unregister functions.

The onCameraOpened/onCameraClosed callbacks are used to notify camera
service client with CAMERA_OPEN_CLOSE_LISTENER permission that a certain
camera device has been opened/closed.

Move libmediandk and libcamera2ndk headers into their module
and export them from there. Also move them to the same path
relative to the export as used in the NDK, media/ for
libmediandk and camera/ for libcamera2ndk.
Test: builds

- For all camera2 paths, and anything shared between the legacy API and
camera2, switch to using strings for camera IDs
- Update ICameraService.addListener to return current set of known
devices and their status, to allow for immediate return of camera
devices when first connecting to camera service
- Remove unused code path for getCameraCharacteristics with HALv1
- Add namespace qualifiers to Binder objects that are also used by
hardware binder.
- Switch to using new HIDL DeviceStatus and TorchStatus enumerations
for better type safety in the service; map more clearly between
the HAL, service-internal, and Binder enums.
