We call disconnectLocked before stopping CameraDevice's looper, in order to avoid this situation:
1) Its possible that an OnResultReceived callback is received, and posts an
AMessage with sp<ACameraCaptureSession> on CameraDevice's looper.
2) Before the looper message is processsed, ACameraDevice_close() is
called by the client, which results in the looper being stopped and
cleared with device lock held.
3) When the looper is getting cleared, the AMessage containg the
ACameraCaptureSession pointer is destructed leading to
~ACameraCaptureSession running without knowing that the device is
being closed, as a result it tries to hold device lock, resulting in
a deadlock.

It's possible that the following sequence happens:
1) hwbinder / binder thread T1: onResultReceived() starts -> promotes wp<CameraDevice> to sp<>;
2) Some other app thread T2 : ACameraDevice_close() -> delete ACameraDevice -> doesn't result in
CameraDevice's destructor running since mCameraDevice has another live
reference, app destroys some object O1.
3) T3 (callback looper thread): callback is received since looper is still running which accesses
dead app object O1 -> results in undefined behavior.
4) T1: onResultReceived completes and CameraDevice is destructed
We need to stop CameraDevice's looper thread (that waits for all callbacks queued to complete) in
~ACameraDevice() so we receive no callbacks after ACameraDevice is closed.

The initial values of the session-wide capture parameters
should be passed along the stream list during stream
configuration. This could yield performance gains depending
on the Hal implementation and support.
