2020-10-16android: post_processor: Introduce a PostProcessor interfaceUmang Jain
Introduce a PostProcessor interface for the streams that require any kind of processing (refer to CameraStream::Type) for their consumption by the HAL layer. The PostProcessor interface can be configured via configure() and the actual processing can be initiated using process(). The post-processing layer can be extended to have multiple post processors for various stream configurations. As of now, we only have one post processor (JPEG), hence the subsequent commit will port its function to this interface.

2020-10-14android: camera_worker: Introduce CameraWorkerJacopo Mondi
The Android camera framework provides for each buffer part of a capture request an acquisition fence the camera HAL is supposed to wait on before using the buffer. As the libcamera HAL runs in the camera service thread, it is not possible to perform a synchronous wait there. Introduce a CameraWorker class that runs an internal thread to wait on a set of fences before queueing a capture request to the libcamera::Camera. Fences completion is handled through a simple poll, similar in implementation to the sync_wait() function provided by libdrm.

2020-09-18android: camera_device: Rework CameraStream handlingJacopo Mondi
The CameraDevice::streams_ vector of CameraStream instances is currently mostly accessed by index. The current implementation creates all the CameraStream during the first loop that inspects the camera3_stream instances and then update the index of the StreamConfiguration associated with the CameraStream during a second loop that inspects MJPEG streams. A third loop creates the JPEG encoder associated with camera streams that produce MJPEG format. As the index-based association is hard to follow and rather fragile, rework the creation and handling of CameraStream: 1) Make the StreamConfiguration index a constructor parameter and a private struct member. This disallows the creation of CameraStream without a StreamConfiguration index assigned. 2) Create CameraStream only after the associated StreamConfiguration has been identified. The first loop creates CameraStream for non-JPEG streams, the second for the JPEG ones after having identified the associated StreamConfiguration. Since we have just created the CameraStream, create the JPEG encoder at the same time instead of deferring it. This change removes all accesses by index to the CameraDevice::streams_ vector. No functional changes intended, but this change aims to make the code easier to follow and more robust.
