There is no need to distinguish between dma bufs allocated outside of
libcamera and internally allocated buffers. As such, remove all the
special case handling of such buffers.

Hardcode the maximum number of buffers imported to the V4L2 video device
to 32. This only has a minor disadvantage of over-allocating cache slots
and V4L2 buffer indexes, but does allow more headroom for using dma
buffers allocated from outside of libcamera.

Don't make an unnecessary call to toV4L2DeviceFormat() from validate()
to get a V4L2DeviceFormat. Instead, the conversion can happen directly
from the RAW stream PixelFormat.

The format to be applied on the sensor is selected by two criteria: the
desired output size and the bit depth. As the selection depends on the
presence of a RAW stream and the streams configuration is handled in
validate() there is no need to re-compute the format in configure().
Centralize the computation of the sensor format in validate() and remove
it from configure().

The findBestFormat() helper operates on the list of sensor formats,
which is owned by the CameraData class. Move the function to that class
as well to:
1) Avoid passing the list of formats to the function
2) Remove a static helper in favour of a class function
3) Allow subclasses with access to CameraData to call the function
Move to the CameraData class the scoreFormat helper as well.

Change the parameter type of `generateConfiguration()` from `const std::vector&`
to `libcamera::Span`. A span is almost always preferable to a const vector ref
because it does not force dynamic allocation when none are needed, and it allows
any contiguous container to be used.
A new overload is added that accepts an initializer list so that
cam->generateConfiguration({ ... })
keeps working.
There is no API break since a span can be constructed from a vector
and the initializer list overload takes care of the initializer lists,
but this change causes an ABI break.

If a user provided pipeline config file is not present, or if the
version reported in the file is invalid, do not return with an error
when creating the pipeline handler. Instead, log a warning message and
return success with default pipeline config values used.
This now matches the behaviour when the pipeline config file could not
be parsed correctly, and we revert to default values.

Do not advertise colour related controls (i.e. [A]WB, colour saturation)
in the ControlInfoMap of available controls returned out to the

Silently ignore these controls in the control handler in case applications
don't use the advertised ControlInfoMap to validate controls.
As a drive-by fix, don't advertise controls::ColourCorrectionMatrix in
the ControlInfoMap as it is not handled by the IPA.

If a user uses a pipeline handler config file where a custom timeout
value is specified, it would lead to a segmentation fault when
loadPipelineConfiguration() tried to access the as yet uninitialised

initialising and registering the pipeline handler and V4L2VideoDevice
objects.

Create a new PipelineHandlerBase class that handles general purpose
housekeeping duties for the Raspberry Pi pipeline handler. Code the
implementation of new class is essentially pulled from the existing
pipeline/rpi/vc4/raspberrypi.cpp file with a small amount of
refactoring.
Create a derived PipelineHandlerVc4 class from PipelineHandlerBase that
handles the VC4 pipeline specific tasks of the pipeline handler. Again,
code for this class implementation is taken from the existing
pipeline/rpi/vc4/raspberrypi.cpp with a small amount of

The goal of this change is to allow third parties to implement their own
pipeline handlers running on the Raspberry Pi without duplicating all of
the pipeline handler housekeeping tasks.

At present, the RPiStream buffer ids == -1 indicates an invalid value.
As a simplification, use id == 0 to indicate an invalid value. This
allows for better code readability.
As a consequence of this, use unsigned int for the buffer id values.

Split the Raspberry Pi pipeline handler and IPA source code into common
and VC4/BCM2835 specific file structures.
For the pipeline handler, the common code files now live in
src/libcamera/pipeline/rpi/common/
and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/.
For the IPA, the common code files now live in
src/ipa/rpi/{cam_helper,controller}/
and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the
camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/.
To build the pipeline and IPA, the meson configuration options have now
changed from "raspberrypi" to "rpi/vc4":
meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4
