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'.

Previously when a frame got cancelled, the frameInfo flags
metadataProcessed and paramDequeued wouldn't get set, meaning that the
request wasn't able to be completed and cancelled.
Make sure that these flags are set when the frame gets cancelled so that
the request can be cancelled.

A range-based for loop whose range expression is an array of char
pointers and range variable declaration is a const reference to a
std::string creates a temporary string from the char pointer and binds
the range variable reference to it. This creates a const reference to a
temporary, which is valid in C++, and extends the lifetime of the
temporary to the lifetime of the reference.
However, lifetime extension in range-based for loops is considered as a
sign of a potential issue, as a temporary is created for every
iteration, which can be costly, and the usage of a reference in the
range declaration doesn't make it obvious that the code isn't simply
binding a reference to an existing object. gcc 11, with the
-Wrange-loop-construct option, flags this:
uvcvideo.cpp:432:33: error: loop variable 'name' of type 'const string&' {aka 'const std::__cxx11::basic_string<cha
r>&'} binds to a temporary constructed from type 'const char* const' [-Werror=range-loop-construct]
| 432 | for (const std::string &name : { "idVendor", "idProduct" }) {
| | ^~~~
To please the compiler, make the range variable a const char *. This may
bring a tiny performance improvement, as the name is only used once, in
a location where the compiler can use
operator+(const std::string &, const char *)
instead of
operator+(const std::string &, const std::string &)

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.

multiple times, which would attempt to open the Unicam embedded data
node on every call. This would cause a warning message as the node
would have already been opened. Avoid this by tracking if the node
has previously been opened.
Note that this is a temporary fix since the open call for the Unicam
embedded data node will be moved from pipeline_handler::configure() to
pipeline_handler::match().

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.

Camera sensors can include an ISP. For instance, the AP1302 external ISP
can be connected to up to two raw camera sensors, and the combination of
the sensors and ISP is considered as a (smart) camera sensor from
libcamera's point of view.
The CameraSensor class has limited support for this already. Extend the
simple pipeline handler to support such sensors, by using the media
entity corresponding to the ISP instead of the raw camera sensor's
entity.
We don't need to handle the case where an entity in the SoC would expose
the MEDIA_ENT_F_PROC_VIDEO_ISP function, as pipeline containing an ISP
would have a dedicated pipeline handler.
The implementation is limited as it won't support other multi-entity
camera sensors (such as CCS). While this would be worth supporting, we
don't have a test platform with a CCS-compatible sensor at this point,
so let's not over-engineer the solution. Extending support to CCS (and
possibly other sensor topologies) will likely involve helpers that can
be used by other pipeline handlers (such as generic graph walk helpers
for instance) and extensions to the CameraSensor class.

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.
