2020-04-28libcamera: ipa: Add support for CameraSensorInfoJacopo Mondi Add support for camera sensor information in the libcamera IPA protocol. Define a new 'struct ipa_sensor_info' structure in the IPA context and use it to perform translation between the C and the C++ API. Update the IPAInterface::configure() operation to accept a new CameraSensorInfo parameter and port all users of that function to the new interface.

The whole model extraction heuristic isn't fully tested as that would require being able to inject different entity names. It is still useful as an initial step.

This is a cumbersome API, especially when reading a single control. Make it nicer by passing the list of V4L2 controls as a vector of control IDs, and returning a ControlList.
