CameraSensorInfo structure is designed to pass in camera sensor related information from pipeline-handler to IPA. Since the pipeline-handler and IPA are connected via mojom IPC IPA interface, the interface itself provides a more suitable placement of CameraSensorInfo, instead of camera_sensor.h (which is a libcamera internal header ultimately, at this point). As CameraSensorInfo is already defined in core.mojom, it is just a matter of removing [skipHeader] tag to allow code-generation of CameraSensorInfo. Finally, update header paths to include CameraSensorInfo definition from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

The controller algorithms currently run on every frame provided to the IPA by the pipeline handler. This may be undesirable for very fast fps operating modes where it could significantly increase the computation cycles (per unit time) without providing any significant changes to the IQ parameters. The added latencies could also cause dropped frames. Pass the FrameBuffer timestamp to the IPA through the controls. This timestamp will be used to rate-limit the controller algorithms to run with a minimum inter-frame time given by a compile time constant, currently set to 16.66ms. On startup, we don't rate-limit the algorithms until after the number of frames required for convergence.

2021-03-04pipeline: ipa: raspberrypi: Pass exposure/gain values to IPA though controlsNaushir Patuck
When running with sensors that had no embedded data, the pipeline handler would fill a dummy embedded data buffer with gain/exposure values, and pass this buffer to the IPA together with the bayer buffer. The IPA would extract these values for use in the controller algorithms. Rework this logic entirely by having a new RPiCameraData::BayerFrame queue to replace the existing bayer queue. In addition to storing the FrameBuffer pointer, this also stores all the controls tracked by DelayedControls for that frame in a ControlList. This includes include exposure and gain values. On signalling RPi::IPA_EVENT_SIGNAL_ISP_PREPARE IPA event, the pipeline handler now passes this ControlList from the RPiCameraData::BayerFrame queue. The IPA now extracts the gain and exposure values from the ControlList instead of using RPiController::MdParserRPi to parse the embedded data buffer.
