1537da7442 pipeline: rpi: Add wallclock timestamp support
A ClockRecovery object is added for derived classes to use, and
wallclock timestamps are copied into the request metadata for
applications.

Wallclock timestamps are derived corresponding to the sensor
timestamp, and made available to the base pipeline handler class and
to IPAs, for both vc4 and pisp platforms.

1d1ba78b45 controls: Add camera synchronisation controls for Raspberry Pi
New controls are added to control the camera "sync" algorithm, which
allows different cameras to synchronise their frames. For the time
being, the controls are Raspberry Pi specific, though this is expected
to change in future.

2a4e347dfe libcamera: Add ClockRecovery class to generate wallclock timestamps
The ClockRecovery class takes pairs of timestamps from two different
clocks, and models the second ("output") clock from the first ("input")
clock.

We can use it, in particular, to get a good wallclock estimate for a
frame's SensorTimestamp.

d3f3b95b64 pipeline: imx8-isi: Dynamically compute crossbar subdevice's first source.
So far, imx8-isi pipeline supports _symetrical_ crossbar, with same
amount of sink and source pads.

But for some other imx SoCs, such as i.MX8QM or i.MX95, crossbar is not
symetric anymore.

Since each crossbar source is already captured as a pipes_ vector entry,
we use pipes_ vector's size to compute 1st source index.

  "1st source index" = "total number of crossbar pads" - pipes_.count()

c50eb1f04a libcamera: framebuffer: Add FrameMetadata::Status::FrameStartup
Add a new status enum, FrameStartup, used to denote that even though
the frame has been successfully captured, the IQ parameters set by the
IPA will cause the frame to be unusable and applications are advised to
not consume this frame. An example of this would be on a cold-start of
the 3A algorithms, and there will be large oscillations to converge to
a stable state quickly.

Additional, update the definition of the FrameError state to cover the
usage when the sensor is known to produce a number of invalid/error
frames after stream-on.

5b7c83d8cc libcamera: process: Pass stderr and reserve stdin and stdout fds
When a child process is started from Process::start(), the file
descriptors inherited from the parent process are closed, except
the ones explicitly listed in the fds[] argument.

One issue is that the file descriptors for stdin, stdout and stderr
being closed, the subsequent file descriptors created by the child
process will reuse the values 0, 1 and 2 that are now available.
Thus, usage of printf(), assert() or alike may direct its output
to the new resource bound to one of these reused file descriptors.
The other issue is that the child process can no longer log on
the console because stderr has been closed.

To address the 2 issues, Process:start() is amended as below:
- Child process inherits from parent's stderr fd in order to share
the same logging descriptor
- Child process stdin, stdout and stderr fds are bound to /dev/null
if not inherited from parent. That is to prevent those descriptors
to be reused for any other resource, that could be corrupted by
the presence of printf(), assert() or alike.

Currently, modifying `controls.py` does not make those build targets dirty
that use a script that includes it (e.g. `gen-controls.py`) because meson

Ideally it would be possible to attach this dependency to `gen_controls`,
`gen_gst_controls`, etc. objects themselves, so that repetition is
avoided, but this does not seem possible at the moment.

efdbe39698 libcamera: controls: Fix ControlInfoMap::count(unsigned int)
The two overloads of `find()` and `at()` have the same behaviour
regardless of the argument type: `unsigned int` or `const ControlId *`.
However, `count()` is not so because `count(unsigned int)` only checks
the `ControlIdMap`, and it does not check if the given id is actually
present in the map storing the `ControlInfo` objects.

So `count()` returns 1 for every control id that is present in the
associated `ControlIdMap` regardless of whether there is an actual
entry for the `ControlId` associated with the given numeric id.

Fix that by simply using `find()` to determine the return value.

f31da7272e libcamera: ipa_module: Avoid unnecessary copy when getting signature
The `signature()` getter can just return a reference to the private vector
member variable, and let the caller make a copy if needed. Since the
return type is const qualified, this was likely the original intention.

6e24360d3f Revert "libcamera: rkisp1: Eliminate hard-coded resizer limits"
This reverts commit e85c7ddd38.

Linux kernel predating 6.4 (specifically commit 7cfb35d3a800 ("media:
rkisp1: Implement ENUM_FRAMESIZES") do not have the ioctl in rkisp1
driver required to dynamically query the resizer limits.

Because of that, maxResolution and minResolution are both {0, 0}
(default value for Size objects) which means filterSensorResolution()
will create an entry for the sensor in sensorSizesMap_ but because the
sensor resolution cannot fit inside the min and max resolution of the
rkisp1, no size is put into this entry in sensorSizesMap_.
On the next call to filterSensorResolution(),
sensorSizesMap_.find(sensor) will return the entry but when attempting
to call back() on iter->second, it'll trigger an assert because the size
array is empty.

Linux kernel 6.1 is supported until December 2027, so it seems premature
to get rid of those hard-coded resizer limits before this happens.

Let's restore the hard-coded resizer limits as fallbacks, actual limits
are still queried from the driver on recent enough kernels.

The DelayedControls instance for the camera sensor is created in
SimplePipelineHandler::configure(). Constant deletion and reconstruction
of a new object is unnecessary, as the control delays are an intrinsic
property of the sensor and are known at initialization time. Move the
DelayedControls creation to the SimpleCameraData class constructor.

183bab1643 pipeline: simple: Enable frame start events
The simple pipeline handler uses frame start events to apply sensor
controls through the DelayedControls class. The setSensorControls()
function applies the controls directly, which would result in controls
being applied twice, if it wasn't for the fact that the pipeline handler
forgot to enable the frame start events in the first place. Those two
issues cancel each other, but cause controls to always be applied
directly.

Fix the issue by only applying controls directly in setSensorControls()
if no frame start event emitter is available, and by enabling the frame
start events in startDevice() otherwise. Disable them in stopDevice()
for symmetry.

2f7bece17b pipeline: simple: Connect/disconnect frameStart signal at start/stop time
The frameStart signal from the frame start emitter is connected in the
configure() function, and is never disconnected. This means that each
time the camera is configured a new connection is made, causing the
DelayedControls::applyControls() to be called multiple times. Fix it by
connecting and disconnecting the signal when starting and stopping the
camera.
