[libcamera-devel] [PATCH 0/2] libcamera: Initial v4l2device object

[Kieran Bingham]

Provide an initial object to handle opening and querying a v4l2device
object.

A test-suite is added to support multiple tests for the object (not all
provided in this series) and an associated update to the test base class
provides a helper to determine if an external test resource is
available.

The v4l2device test base class expects /dev/video0 to be a valid video
capture device node. This will not always be the case and instead
(later) it should iterate all video device nodes and identify a suitable
device to utilise in testing.

There are further patches on top of this - but they're not yet ready,
and sending this out gives us the opportunity to incorporate a
v4l2device object for consumption by other developers, while the API
grows.
