Define the beginnings of a V4L2 device management object.

This basic class supports opening the device and parsing the device
capabilities including obtaining the driver and device (card) name.

The capabilities are validated to ensure that the device is a capture
device and supports the Streaming IO ioctls.

This series imports the linux/videodev2.h from kernel version v4.19.

Kieran Bingham (3):
  include: linux: Import videodev2.h from Linux v4.19
  libcamera: Add V4L2 Device object
  test: v4l2_device: Add test suite and initial test
