The cameraservice is only registered to service manager after onFirstRef
is returned. To reduce the probability of getBinderService() call
returning null, move pingCameraServiceProxy to end of onFirstRef().
Also add debug messages in onFirstRef and main() for better diagnoses.
Test: Camera CTS

Some interactions between camera service and hwservicemanager require
multiple threads to execute without deadlocks, such as calling
getService() from within an onRegistered() callback.
Increase thread count to 3 to accomodate.
Also switch the order of listener registration and legacy provider
addition back to what it was originally.
Test: No deadlock when camera service is restarted
