2020-01-12v4l2: Rename FrameMetadata to V4L2FrameMetadataNiklas Söderlund
With the upcoming FrameBuffer API a new library wide FrameMetadata object will be added which will replace the specific implementation in the V4L2 compatibility layer. Avoid name collisions while the new FrameBuffer API is added by renaming the V4L2 compatibility layer specific implementation until it can be replaced with the library wide implementation.

Now that Object::invokeMethod() supports returning a value, use it and drop the return value method argument. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-01-03v4l2: v4l2_compat: Add V4L2 compatibility layerPaul Elder
Add libcamera V4L2 compatibility layer. This initial implementation supports the minimal set of V4L2 operations, which allows getting, setting, and enumerating formats, and streaming frames from a video device. Some data about the wrapped V4L2 video device are hardcoded. Add a build option named 'v4l2' and adjust the build system to selectively compile the V4L2 compatibility layer. For now we match the V4L2 device node to a libcamera camera based on a devnum that a pipeline handler may optionally map to a libcamera camera.
