Fix a race-condtion in SurfaceFlinger that could lead to a crash. Client::mLayers could be accessed from different threads. On one side from Client::attachLayer() which is currently called from a binder thread; on the other side from Client::detachLayer() which is always called from the main thread. This could lead to a corruption of Client::mLayers. We fix this issue by adding an internal lock to Client. Change-Id: Ib1317d7750ed5030e6f577efe34b69fc10198bd3
