android: Wait on fences in CameraStream::process()
Acquire fences for streams of type Mapped generated by post-processing are not correctly handled and are currently ignored by the camera HAL. Fix this by adding CameraStream::waitFence(), executed before starting the post-processing in CameraStream::process(). The change applies to all streams generated by post-processing (Mapped and Internal) but currently acquire fences of Internal streams are handled by the camera worker. Postpone that to post-processing time by passing -1 to the Worker for Internal streams. Also correct the release_fence handling for failed captures, as the framework requires the release fences to be set to the acquire fence value if the acquire fence has not been waited on.
