Laurent Pinchart d6d4710d04 libcamera: framebuffer: Make FrameBuffer class Extensible
Implement the D-Pointer design pattern in the FrameBuffer class to allow
changing internal data without affecting the public ABI.

Move the request_ field and the setRequest() function to the
FrameBuffer::Private class. This allows hiding the setRequest() function
from the public API, removing one todo item. More fields may be moved
later.

Laurent Pinchart 6a31a8d8e2 libcamera: buffer: Rename buffer.h to framebuffer.h
libcamera names header files based on the classes they define. The
buffer.h file is an exception. Rename it to framebuffer.h.

Hirokazu Honda 5a9d19210f libcamera: pipeline: ipu3: Try queuing pending requests if a buffer is available
IPU3CameraData stores requests that have been failed due to a
buffer shortage. The requests should be retried once enough
buffers are available. This sets the retry function as signal to
CIO2Device and IPU3Frame, and invokes it from
CIO2Device::tryReturnBuffer() and IPU3Frame::remove().

Hirokazu Honda 89dae58449 libcamera: pipeline: ipu3: Store requests in the case a buffer shortage
PipelineHandlerIPU3 returns -ENOBUFS and -ENOMEM on queueing a
request when there are not sufficient buffers for the request.
Since the request will be successful if it is queued later when
enough buffers are available. The requests failed due to a buffer
shortage should be stored and retried later in the FIFO order.
This introduces the queue in IPU3CameraData to do that.

Kieran Bingham 47c12e2635 libcamera: pipeline: ipu3: frames: Fail if the FrameInfo can't be found
The FrameInfo structure associates the data sent to the IPA
and is essential for handling events.

If it can not be found, this is a fatal error which must be fixed.

While we're changing the line, also correct a spelling error for
'Information'.

Kieran Bingham 6084217cd3 libcamera: pipeline: ipu3: frames: Use the request sequence
For all frame indexes, use the same sequence number as generated
by the Request object.

This allows clear matching of what operations occurred to which request.

Ensure that the buffers are associated with the request even if they are
used internally to be able to correctly map back to the resources they
are being used to fulfil.

Niklas Söderlund d2bc3eb7b6 libcamera: ipu3: Add helper for parameter and statistic buffers
Add a helper class to aid in associating a parameter and statistic
buffer with each request queued to the pipeline. The helper helps with
tracking the state of the extra buffers and in completing the request
once all extra processing is done.

This change only adds the helper more work is needed to integrate it
with the pipeline and an IPA.
