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.

Currently the camera subsystem is trying to store all cameras, that
have ever been registered with it by camera HALs. This makes it
easier for the framework, but with hotpluggable cameras it makes
little sense, because for this HALs also have to store all cameras,
that have ever been plugged in and with every new plug in event
identify, whether this is a new camera or a known one. An easier and
cleaner approach is to remove cameras upon unplug. This patch
implements that.

Different vendors could have different vendor tags.
A global vendor tag cache will store all available
vendor tag descriptors from different providers.
The cache will then be shared with each camera client.
Camera metadata will use specific vendor ids stored
in the metadata buffer to identify the correct vendor
tag provider.

The NDK CameraManager only lists cameras that support camera API v2. For
a device that only supports v1 the list comes back empty. This results
in allocating an array of size zero. This array was then intialized with
a nullptr. This is fine if the array contains at least one item but in
the case where there are no cameras this will cause a buffer overflow.
This change removes the initialization which fixes the crash.
Test: manual - ran camera CTS tests

- 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.

On Android Wear devices we don't have cameras, so we don't need the
proxy service as well. If it is disabled by the system property, don't
wait for it to start, but rather return null pointer in
getCameraService(), which causes getNumberOfCameras() to report zero
cameras available.
The same logic applies to ACameraManager, where we return an empty list.
