In an attempt to clarify the license terms of all files in the libcamera
project, the build system files deserve particular attention. While they
describe how the binaries are created, they are not themselves
transformed into any part of binary distributions of the software, and
thus don't influence the copyright on the binary packages. They are
however subject to copyright, and thus influence the distribution terms
of the source packages.
Most of the meson.build files would not meet the threshold of
originality criteria required for copyright protection. Some of the more
complex meson.build files may be eligible for copyright protection. To
avoid any ambiguity and uncertainty, state our intent to not assert
copyrights on the build system files by putting them in the public
domain with the CC0-1.0 license.

The V4L2Device::getControls() function takes a ControlList that needs to
be pre-populated with dummy entries for the controls that need to be
read. 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.

Add test to test the different modes and situations the V4L2BufferCache

The ControlInfoMap and V4L2ControlInfoMap classes are very similar, with
the latter adding convenience accessors based on numerical IDs for the
former, as well as a cached idmap. Both features can be useful for
ControlInfoMap in the context of serialisation, and merging the two
classes will further simplify the IPA API.
Import all the features of V4L2ControlInfoMap into ControlInfoMap,
turning the latter into a real class. A few new constructors and
assignment operators are added for completeness.

The V4L2Device class uses V4L2ControlList as a controls container for
the getControls() and setControls() operations. Having a distinct
container from ControlList will makes the IPA API more complex, as it
needs to explicitly transport both types of lists. This will become even
more painful when implementing serialisation and deserialisation.
To simplify the IPA API and ease the implementation of serialisation and
deserialisation, replace usage of V4L2ControlList with ControlList in
the V4L2Device (and thus CameraSensor) API. The V4L2ControlList class
becomes a thin wrapper around ControlList that slightly simplifies the
creation of control lists for V4L2 controls, and may be removed in the
future.

Most of the video device tests are based on vimc and Linux commit
85ab1aa1fac17bcd ("media: vimc: deb: fix default sink bayer format")
changes the default media bus format for the debayer subdevices. This
leads to a -EPIPE error when trying to use the raw capture video device
nodes.
Fix this by explicitly setting media bus and pixel formats to known good
values which works before and after the upstream change.

When stopping the stream buffers have been queued, in which case their
completion is never be notified to the user. This can lead to memory
leaks. Fix it by notifying completion of all queued buffers with the
status set to error.
As a result the base PipelineHandler implementation can be simplified,
as all requests complete as the result of stopping the stream. The
stop() method that manually completes all queued requests isn't needed
anymore.
