The comment block at the beginning of the core.mojom file is meant to
provide an overview of how to use libcamera defined types in the definition
of mojom interfaces.
As the IPA/IPC interface definition mechanism evolved, the documentation
has not been updated accordingly.
Update the file comments to match the most recent IPA/IPC
interface definition and generation mechanism.

Move the functionality for the following components to the new
base support library:
- BoundMethod
- EventDispatcher
- EventDispatcherPoll
- Log
- Message
- Object
- Signal
- Semaphore
- Thread
- Timer
While it would be preferable to see these split to move one component
per commit, these components are all interdependent upon each other,
which leaves us with one big change performing the move for all of them.

The IPU3 IPA interface does not define a return value from configure().
This prevents errors from being reported back to the pipeline handler
when they occur in the IPA.
Update the IPU3 IPA interface and add return values to the checks in
IPAIPU3::configure() accordingly

CameraSensorInfo structure is designed to pass in camera sensor related
information from pipeline-handler to IPA. Since the pipeline-handler
and IPA are connected via mojom IPC IPA interface, the interface
itself provides a more suitable placement of CameraSensorInfo,
instead of camera_sensor.h (which is a libcamera internal header
ultimately, at this point).
As CameraSensorInfo is already defined in core.mojom, it is just
a matter of removing [skipHeader] tag to allow code-generation
of CameraSensorInfo.
Finally, update header paths to include CameraSensorInfo definition
from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

Moving the core.mojom documentation to its corresponding .cpp file
(core_ipa_interface.cpp). This will allow Doxygen to generate the
documentation for IPABuffer, IPASettings and IPAStream structures.
Since the .mojom files are placed in include/ directory, the .cpp file
will live in $sourcedir/src/libcamera/ipa/ - which can also contain
documentation for other mojom generated IPA interfaces in subsequent
commit.
Also hide the constructors in generated IPA interface from doxygen,
via #ifndef __DOXYGEN__. These constructors provide no major value in
documenting them, instead will spew out doxygen warnings during the

For structs defined in core.mojom that have the skipHeader tag, if
they're only used in function parameters (in a mojom file) then a

insufficient, and the definition needs to be included. Do so for

When running with sensors that had no embedded data, the pipeline handler
would fill a dummy embedded data buffer with gain/exposure values, and
pass this buffer to the IPA together with the bayer buffer. The IPA would
extract these values for use in the controller algorithms.
Rework this logic entirely by having a new RPiCameraData::BayerFrame
queue to replace the existing bayer queue. In addition to storing the
FrameBuffer pointer, this also stores all the controls tracked by
DelayedControls for that frame in a ControlList. This includes include
exposure and gain values. On signalling RPi::IPA_EVENT_SIGNAL_ISP_PREPARE
IPA event, the pipeline handler now passes this ControlList from the
RPiCameraData::BayerFrame queue.
The IPA now extracts the gain and exposure values from the ControlList
instead of using RPiController::MdParserRPi to parse the embedded data
buffer.

libcamera: IPAProxy, IPAManager: Switch to one-proxy-per-pipeline scheme
IPAProxy is changed in two major ways:
- Every pipeline has its own proxy, to support each pipeline's IPA
interface
- IPAProxy implementations always encapsulate IPA modules, and switch
internally for isolation or threaded
The IPAProxy registration mechanism is removed, as each pipeline will
have its own proxy, so the pipeline can pass the specialized class name
of the IPAProxy to the IPAManager for construction.
IPAManager is changed accordingly to support these changes:
- createIPA is a template function that takes an IPAProxy class, and
always returns an IPAProxy
- IPAManager no longer decides on isolation, and simply creates an
IPAProxy instance while passing the isolation flag
Consequently, the old IPAProxy classes (IPAProxyThread and
IPAProxyLinux) are removed. The IPAInterfaceTest is updated to use
the new IPAManager interface, and to construct a ProcessManager as no
single global instance is created anymore.

The application provided noise reduction mode gets passed into the
denoise controller. The denoise controller in turn returns the mode to
the IPA which now sets up the colour denoise processing appropriately.

Add an empty IPA skeleton for the IPU3 pipeline. The skeleton IPA
handles the flow of parameter and statistic buffers but does not read or
write anything in the buffers. It also allows the IPA to set sensor
controls but does not implement any logic to set optimal values and
instead sets the V4L2 exposure and gain controls to max and keeps them
at that setting.
This IPA is meant as a base to allow the pipeline handler to be wired up
to an IPA. The image algorithms can then later be added to the IPA
independently from also having to add plumbing to the pipeline handler.

Users are free to avoid loading certain control algorithms from the
json tuning file if they wish, and this could mean that some libcamera
controls will therefore not be available. Currently we don't have a
good means of indicating which these are, therefore failing completely
when an application tries to use one is unhelpful - it is better just
to issue a warning.
Note that once we can indicate this properly, applications should
check for supported controls as this change may be reverted.

At startup, ControlInfoMap::generateIdmap() threw a log message warning
that the controls::FrameDurations had a type mismatch based on the
min/max values provided in libcamera::RPi::Controls initialiser.
Fix this warning by forcing the integer constants to be 64-bit wide by
using the INT64_C() macro.

Add support for setting V4L2_CID_VBLANK appropriately when setting
V4L2_CID_EXPOSURE. This will allow adaptive framerates during
viewfinder use cases (e.g. when the exposure time goes above 33ms, we
can reduce the framerate to lower than 30fps).
The minimum and maximum frame durations are provided via libcamera
controls, and will prioritise exposure time limits over any AGC request.
V4L2_CID_VBLANK is controlled through the staggered writer, just like
the exposure and gain controls.

This change allows controls passed into PipelineHandler::start to be
forwarded onto IPAInterface::start(). We also add a return channel if the
pipeline handler must action any of these controls, e.g. setting the
analogue gain or shutter speed in the sensor device.
The IPA interface wrapper isn't addressed as it will soon be replaced by
a new mechanism to handle IPC.

If the IPA fails during configuration, return an error flag to the
pipeline handler and fail the use case gracefully.
At present, the IPA configuration can fail for the following reasons:
- The sensor is not recognised, and fails to open a CamHelper object.
- The pipeline handler did not pass in controls for the ISP and sensor.

During configure() we update the ScalerCropMaximum to the correct
value for this camera mode and work out the minimum crop size allowed
by the ISP.
Whenever a new ScalerCrop request is received we check it's valid and
apply it to the ISP V4L2 device. When the IPA returns its metadata to
us we add the ScalerCrop information, rescaled to sensor native
pixels.

The pipeline-specific IPA headers are not part of the libcamera API,
they should thus be skipped when generating documentation. doxygen
doesn't complain currently due to the fact that types defined in those
headers are part of undocumented namespaces. In preparation for
documenting the libcamera namespace, make sure the headers don't get
parsed by doxygen.
Only vimc.h needs a header guard, as rkisp1.h uses the global namespace
and raspberrypi.h uses the undocumented libcamera::RPi namespace,
neither of which cause issues. Still, for consistency, add header guards
to all headers.
