Naushir Patuck e96d02015c pipeline: raspberrypi: Fix the buffer count calculation for the ISP input stream
The ISP input stream currently only allocates a single slot in the
V4L2VideoDevice cache as it follows the number of buffers allocated for use.
However, this is wrong as the ISP input stream imports buffers from Unicam
image stream.  As a consequence of this, only one cache slot was used during
runtime for the ISP input stream, and if multiple buffers were to be queued
simultaneously, the queue operation would return a failure.

Fix this by passing the same number of RAW buffers available from the Unicam
image stream. Additionally, double this count in the cases where buffers could
be allocated externally from the application.

Naushir Patuck 7b84a17e21 pipeline: raspberrypi: Return all ISP resolutions from generateConfiguration()
The libcamerasrc gstreamer component does seem to not allow stream resolutions
that are not advertised by PipelineHandler::generateConfiguration(). This has
been raised in a bug report [1].

Fix this behavior by advertising a SizeRange from the minimum ISP resolution, up
to the sensor resolution from PipelineHandlerRPi::generateConfiguration().

Naushir Patuck a3b0aa5511 pipeline: raspberrypi: Rework the internal buffer allocation scheme
For simplicity, the pipeline handler currently look at the maximum number of
buffers set in the StreamConfiguration by the user and allocate the same number
of internal buffers for all device nodes. This would likely overallocate buffers
for some nodes. Rework this logic to try and minimise overallcations without
compromising performance.

The key change is to mostly decouple the number of internal buffers allocated
from number of buffers requested by the user through the StreamConfiguration.

For ISP nodes, we only ever need 1 set of internal buffers, as the hardware runs
synchronous with the requests and IPA.

For Unicam nodes, allocate a minimum for 4 buffers (exported + internal), but
also require at least 2 internal buffers to minimise frame drops.

Laurent Pinchart 395d43d6d7 libcamera: v4l2_videodevice: Drop toV4L2PixelFormat()
The V4L2VideoDevice::toV4L2PixelFormat() function is incorrectly
implemented, as it will pick a multi-planar format if the device
supports the multi-planar API, even if only single-planar formats are
supported. This currently works because the implementation calls
V4L2PixelFormat::fromPixelFormat(), which ignores the multiplanar
argument and always returns a single-planar format.

Fixing this isn't trivial. As we don't need to support multi-planar V4L2
formats at this point, drop the function instead of pretending
everything is fine, and call V4L2PixelFormat::fromPixelFormat() directly
from pipeline handlers. As the single-planar case is the most common,
set the multiplanar argument to false by default to avoid long lines.

Naushir Patuck e87fb20f8f pipeline: raspberrypi: Fix a bug when clearing out Request buffers on stop
When RPiCameraData::clearIncompleteRequests() clears out the request
queue during a stop condition, it unconditionally calls completeBuffer()
on all buffers in each request.  This is wrong, as a buffer could have
already been completed as part of the current request, but the request
itself may not yet have completed.

Fix this by checking if the buffers in the request have been completed
before cancelling them.

Kieran Bingham 27aff949fb libcamera/base: Move extended base functionality
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.

Naushir Patuck d832e9622e pipeline raspberrypi: Move adding of ScalerCrop to the Request metadata
With the recent change to merge existing Request metadata with the
ControlList provided by the IPA in commit fcfb1dc02a ("libcamera:
raspberry: Report sensor timestamp"), we can now write the
controls::ScalerCrop value at the start of the pipeline instead of at
the end.

This change simplifies the logic slightly, and allows us to write all
metadata items to the Request in one place.

Naushir Patuck 99feb66df0 ipa: raspberrypi: Rate-limit the controller algorithms
The controller algorithms currently run on every frame provided to the
IPA by the pipeline handler. This may be undesirable for very fast fps
operating modes where it could significantly increase the computation
cycles (per unit time) without providing any significant changes to the
IQ parameters. The added latencies could also cause dropped frames.

Pass the FrameBuffer timestamp to the IPA through the controls. This
timestamp will be used to rate-limit the controller algorithms to run
with a minimum inter-frame time given by a compile time constant,
currently set to 16.66ms. On startup, we don't rate-limit the algorithms
until after the number of frames required for convergence.
