Register controls for the IPU3 pipeline handler. The only supported
Camera control is currently the pipeline depth control.
Report the minimum and maximum values the pipeline handler supports for
the pipeline processing stages and report for each request the pipeline
depth describing the number of processing steps the frames went through.

The libcamera control definition schema includes a placeholder
maximum value for each enumeration of supported values.
As it is now possible to create ControlInfo from the list of enumerated
values, it is not necessary to generate the placeholder value anymore.

For each Control that supports enumerated values generate an array
of ControlValue which contains the full list of valid values.
At the expense of a slight increase in memory occupation this change
allows the construction of the ControlInfo associated with a Control
from the values list, defaulting the minimum and maximum values
reported by the ControlInfo.

libcamera is in the process of defining its own set of controls
to enable applications to control the image capture process and
return information on the captured frames.
To temporarily close the gap in the Android camera HAL and support all
controls required in the LIMITED hardware level, define a set of Draft
controls whose values are taken from their Android definition, in order
to allow pipeline handlers to support Android.

Extend the control and property framework to support exposing draft
controls and properties in a scoped namespace.
The controls/properties themselves will retain the same ordering in the
relevant enum/id maps - but the access to any draft control will require
explicitly referencing through its' draft:: namespace prefix.

The rkisp1 and simple pipeline handlers can fail to register any camera,
if initialization of all the detected cameras fail. In that case, they
still return success from their match function. As no camera gets
registered, the pipeline handler is immediately destroyed, releasing the
acquired media devices, and the camera manager immediately tries to
match the same pipeline handler with the same media device, causing an
endless loop.
Fix it by returning false from the match function if no camera gets
registered.

Introduce a PostProcessor interface for the streams that require any
kind of processing (refer to CameraStream::Type) for their consumption
by the HAL layer. The PostProcessor interface can be configured via
configure() and the actual processing can be initiated using process().
The post-processing layer can be extended to have multiple post
processors for various stream configurations. As of now, we only have
one post processor (JPEG), hence the subsequent commit will port its
function to this interface.

Fences completion is handled through a simple poll, similar in

The current simple pipeline handler refuses to work with capture devices
which have V4L2_CAP_VIDEO_CAPTURE_MPLANE flag set in the device capabilities
field. This is too restrictive, as devices supporting the multi-planar API
can be using contiguous memory for semi-planar and planar formats, and this
would just work without any changes to libcamera.
Drop the guard against MPLANE devices, and replace it with the check of
the number of planes in the format the simple pipeline handler is going to
use for capture. This will let MPLANE devices which don't use non-contiguous
memory for frame buffers to work with the simple pipeline handler.
The following code in SimpleCameraData::init() filters out the pixel formats
libcamera doesn't support:
PixelFormat pixelFormat = videoFormat.first.toPixelFormat();
if (!pixelFormat)
continue;
So the check for the number of memory planes this patch adds would not
trigger until non-contiguous planar formats becomes supported in libcamera,
and video devices using these formats are enabled in the simple pipeline
handler. Then this check will remind one to review the simple pipeline
handler code.
