Camera2: Add prepare method for output buffer pre-allocation Normally, buffers for camera output Surfaces are allocated as needed. This minimizes memory overhead and time to first frame. However, if allocation takes a long time, as it can do for full-resolution output buffers, full frame rate may not be maintainable with the added allocation overhead. The prepare() method allows an application to indicate that buffers for a given output Surface should be preallocated by the camera device. Once the allocation is complete, the onSurfacePrepared callback is invoked. The application may then use the prepared Surface without concerns about allocation-caused delays.

Camera2: Add frameNumber to CaptureCallback#onCaptureStarted Otherwise, cannot reliably match up capture progressed and failure callbacks with the start callback. Bug: 17421092 Change-Id: I91d92be70a15536b215bac330370ce37e426ec26

Camera2: Final API revisions - Rename listeners to callbacks. Listeners are single-method and are interfaces, while callbacks are abstract may get more methods in the future. - Use register/unregister for registering callbacks, not add/remove. Bug: 17389922 Change-Id: Ic6b46ad79cb43a43a85e2a4b63f059d3af99798b
