When iterating over enabled pipelines and IPA modules, libcamera
descends into subdirectories in a recursive manner, which involves
nested loops. Both the outer and inner loops use the same loop variable
named 'pipeline'. As the outer loop uses the variable after descending
into the inner directory, it ends up using an incorrect value. Fix it by
moving all use of the variable before the subdir() call, and add a
comment that warns about the issue to avoid reintroducing it.

Now that we allow IPA modules to live in nested directories for the
RaspberryPi platform, it is required to allow parsing one more level
to be able to run libcamera from the source directory.
Without this patch the $(builddir)/src/ipa/rpi/vc4/ipa_rpi_vc4.so
IPA module cannot be loaded.
The issue is only present when running from the source directory
as when libcamera is installed all IPA modules are deployed to a single
$(prefix)/$(libcamera_libdir)/libamera/ location.

Files opened internally in libcamera without the O_CLOEXEC file will
remain open upon a call to one of the exec(3) functions. As exec()
doesn't destroy local or global objects, this can lead to various side
effects. Avoid this by opening file descriptors with O_CLOEXEC for all
internal files.
The O_CLOEXEC flag should also be set when obtaining file handles from
the V4L2 VIDIOC_EXPBUF operation, but was missed during the updates to
both d942bdc913c5 ("libcamera: v4l2_device: openat(2) with O_CLOEXEC to
cleanup after exec(3)") and 436b38fd89fe ("libcamera: Open files with
O_CLOEXEC").
Set the O_CLOEXEC flag on calls to ioctl(VIDIOC_EXPBUF).

Move the v4l2-compat.so shared library installation to the libcamera
directory under libexec. This is the same location that the proxy
workers live and will facilitate easier packaging of the V4L2
compatibility layer with distributions.
Create a new libcamera_libexecdir variable within meson to simplify
representation of this path and update the proxy worker meson.build
infrastructure to make use of it as well.

The STM32 contains a camera pipeline known as the DCMIPP (Digital
Camera-Memory Interface Pixel Processor) which receives data from a
parallel interface and dumps the post-processed data to memory. The
pipeline is capable of some processing in the form of downscaling
captured data through cropping or skipping the sensor's output.
The simple pipeline handler is quite capable of handling the DCMIPP
given its operation is handled entirely through configuring the pads
of a media graph, so add support for the driver to the pipeline's
supportedDevices array.

At generateConfiguration() a YUV/RGB pixel format is preferred for the
StillCapture/VideoRecording/Viewfinder roles, but currently there are no
guarantees in place that the sensor provides a non-Bayer bus format from
which YUV/RGB can be generated.
This makes the default configuration generated for those roles not to
work if the sensor is a RAW-only one.
To improve the situation split the configuration generation in two,
one for YUV modes and one for Raw Bayer mode.
StreamRoles assigned to a YUV mode will try to first generate a YUV
configuration and then fallback to RAW if that's what the sensor can
provide.
As an additional requirement, for YUV streams, the generated mode has to
be validated with the sensor to confirm the desired sizes can be
generated as the ISI cannot up-scale. In order to test a format use the
newly introduced CameraSensor::tryFormat().

As per the RAW format selection, the media bus format selection
procedure relies on the direct association of PixelFormat and media
bus code in the formatsMap_ map.
As the ISI can generate YUV and RGB formats from any non-Bayer media
bus format, break out the YUV/RGB media bus format selection to a
separate function.
The newly introduced getYuvMediaBusFormat() tests a list of
known-supported media bus formats against the list of media bus
formats supported by the sensor and tries to prefer media bus
codes with the same encoding as the requested PixelFormat.
Use the newly introduced function in
ISICameraConfiguration::validateYuv() to make sure the sensor can
produce a YUV/RGB media bus format.

The current implementation of the ISI pipeline handler handles
translation of PixelFormat to media bus formats from the sensor
through a centralized map.
As the criteria to select the correct media bus code depends on if the
output PixelFormat is a RAW Bayer format or not, start by splitting
the RAW media bus code procedure selection out by adding a function
for such purpose to the ISICameraData class.
Add the function to the ISICameraData and not to the
ISICameraConfiguration because:
- The sensor is a property of CameraData
- The same function will be re-used by the ISIPipelineHandler
during CameraConfiguration generation.

It's possible to construct a Camera with an unsafe controlInfo_.
This is the case in the Simple pipeline, where the camera controls are
not populated.
With Simple, if we attempt to set a Control, we end up with a segfault
because the default constructor for ControlInfoMap doesn't
intialized idmap_ which is initialized at class declaration time as
const ControlIdMap *idmap_ = nullptr;
Add some safeguards in ControlInfoMap to handle this case.

In `udevNotify()`, constructing an std::string from the device's
associated action is unnecessary as it is only compared against static
strings, and for that purpose an std::string_view works just as well,
while being cheaper to construct.
In the same vein, an std::string_view can be used to store the device's
devnode initially, and the string construction can be deferred until it
is needed.
Furthermore, previously `udev_device_get_devnode()` was called twice.
The extra call is now removed.

The algorithm uses the data type std::vector<std::array<double, 4>> to
represent the large sparse matrices that are XY (X, Y being the ALSC
grid size) high but with only 4 non-zero elements on each row.
Replace this slightly long type name by SparseArray<double>.
No functional changes.

The Array2D class is a very thin wrapper round std::vector that can be
used almost identically in the code, but it carries its 2D size with
it so that we aren't passing it around all the time.
All the std::vectors that were X * Y in size (X and Y being the ALSC
grid size) have been replaced. The sparse matrices that are XY * 4 in
size have not been as they are somewhat different, are used
differently, require more code changes, and actually make things more
confusing if everything looks like an Array2D but are not the same.
There should be no change in algorithm behaviour at all.

Remove any hard-coded assumptions about the target hardware platform
from the ALSC algorithm. Instead, use the "target" string provided by
the camera tuning config and generalised statistics structures to
determing parameters such as grid and region sizes.
The ALSC calculations use run-time allocated arrays/vectors on every
frame. Allocating these might add a non-trivial run-time penalty.
Replace these dynamic allocations with a set of reusable pre-allocated
vectors during the init phase.

Add a new Controller::HardwareConfig structure that captures the
hardware statistics grid/histogram sizes and pipeline widths. This
ensures there is a single centralised places for these parameters.
Add a getHardwareConfig() helper function to retrieve these values for a
given hardware target.
Update the statistics populating routine in the IPA to use the values
from this structure instead of the hardcoded numbers.

The target string may be used by algorithms to determine the running
hardware target.
Store the target string provided by the camera tuning files in the
controller state. Add a getTarget() member function to retrieve this
string.
Validate the correct hardware target ("bcm2835") during the IPA
initialisation phase.

Fix a bug in the default frame durations calculation where the min/max
values are swapped round. This is a rarely travelled code path, so has
not actually caused a reported failure.

Make a copy of the CameraMode structure on a switch mode call. This
replaces the existing lastSensitivity_ field.
Limit the AGC gain calculations to the minimum value given by the
CameraMode structure. The maximum value remains unclipped as any gain
over the sensor maximum will be made up by digital gain.
Rename clipShutter to limitShutter for consistency, and have the latter
limit the shutter speed to both upper and lower bounds.

When an executable using libcamera calls exec(3) while a camera is in
use, file descriptors corresponding to the V4L2 video devices are kept
open has they have been created without O_CLOEXEC. This results in the
video devices staying busy, preventing the new executable from using
them:
[91] ERROR V4L2 v4l2_videodevice.cpp:1047 /dev/video0[149:cap]: Unableto set format: Resource busy
Fix this by opening video devices with O_CLOEXEC, which is generally a
good idea in libraries.
