Do not send events back to the pipeline handler, while the IPA thread
has not been started.
If information needs to be returned from configure it should be returned
directly.
Move the initial call to setControls() out of configure() and into the
start() method which is called after the IPA running_ state is updated.

CameraDevice::camera() originally returns shared_ptr. It is
mandatory to make a copy by calling camera() in this way. There
is no need of copying if a caller needs the reference of the
camera like const shared_ptr<Camera> &cam = camera(). That is, it
is a caller that copying is required. This changes the return
type of camera() to const shared_ptr&, so that we are able to
reduce one redundant copy in the above case.

The V4l2 buffer cache allows us to map incoming buffers to an instance
of the V4L2 buffer required to actually queue.
If the cache_ is not available, then the buffers required to allow
queuing to a device have been released, and this indicates an issue at
the pipeline handler.
This could be a common mistake, as it could happen if a pipeline handler
always requeues buffers to the device after they complete, without
checking if they are cancelled.
Catch any invalid queueing of buffers to the V4L2 video device when
resources have been released by adding a Fatal log message to highlight
the error during development.

When the imguOutputBufferReady() detects a cancelled frame, it is
reporting that the metadata has been processed in order to be able to
complete the cancelled request.
This causes the FrameInfo to be completed and deleted early, but then an
active buffer on the IMGU can complete and be unable to find the
FrameInfo for it to complete correctly.
Do not mark metadataProcessed early on the event that a single buffer is
detected as cancelled. The stopping of the V4L2 devices will ensure
that all queued buffers are returned to us and we can follow the normal
and expected shutdown sequence.

When the SimplePipeline is setting up its data and media pipeline in the
SimpleCameraData constructor, it merely tries to find the first valid
pad and link to the next entity, starting from the camera sensor.
Following this path may not always lead to a valid capture device and
therefore the setup will fail on some machines. This is for example an
issue when using the SimplePipeline on an i.MX-6Q with its i.MX IPU.
This commit implements a different approach to setup the media-pipeline
by finding the shortest path to a valid capture device, using the
breadth-first search algorithm. On i.MX6Q, the shortest path has a good
chance to be the path from the sensor to the CSI capture device, as
other paths may involve image converters, encoders or other IPU blocks
and will have therefore more nodes.

If gst_buffer_pool_acquire_buffer in gst_libcamera_task_run fails, the
unique_ptr to the request-object gets reset and hence, its destructor
is called. However, the wrap-object points to the same object and is
still alive at this moment. When the task_run-function is finished, the
destructor of the wrap-object is called, which in return calls the
destructor of the request-object again.
Instead of taking care of both, the request and the wrap-object, we can
move the request to the wrap which will then effectively take care of
the request object automatically.

In DelayedControls::applyControls(), the controls queue would be
extended via a no-op control push to fill the intermittent slots with
unchanged control values. This is needed so that we read back unchanged
control values correctly on every frame.
However, there was one additional no-op performed on every frame that is
not required, meaning that any controls queued by the pipeline handler
would have their write delayed by one further frame. The original
StaggeredCtrl did not do this, as it only had one index to manage,
whereas DelayedControls uses two.
Remove this last no-op push so that the pipeline_handler provided
controls would be written on the very next frame if possible. As a
consequence, we must mark the control update as completed within the
DelayedControls::applyControls() loop, otherwise it might get reused
when cycling through the ring buffer.

On DelayedControls::reset(), the values retrieved from the sensor device
were added to the queues with the updated flag set to true. This would
cause the helper to write out the value to the device again on the first
DelayedControls::applyControls() call. This is unnecessary, as the
controls written are identical to what is stored in the device driver.
Fix this by explicitly setting the update flag to false in
DelayedControls::reset() when adding the controls to the queue.
Additionally, use the Info() constructor when adding items to the queue
for consistency.

If an exposure time change adjusts the vblanking limits, and we set both
VBLANK and EXPOSURE controls through the VIDIOC_S_EXT_CTRLS ioctl, the
latter may fail if the value is outside of the limits calculated by the
old VBLANK value. This is a limitation in V4L2 and cannot be fixed by
setting VBLANK before EXPOSURE in a single VIDIOC_S_EXT_CTRLS ioctl.
The workaround here is to have the DelayedControls object mark the
VBLANK control as "priority write", which then write VBLANK separately
from (and ahead of) any other controls. This way, the sensor driver will
update the EXPOSURE control with new limits before the new values is
presented, and will thus be seen as valid.
To support this, a new struct DelayedControls::ControlParams is used in
the constructor to provide the control delay value as well as the
priority write flag.
