This commit does the basic reorganisation of the code in order to
implement multi-channel AGC. The main changes are:
* The previous Agc class (in agc.cpp) has become the AgcChannel class
in (agc_channel.cpp).
* A new Agc class is introduced which is a wrapper round a number of
AgcChannels.
* The basic plumbing from ipa_base.cpp to Agc is updated to include a
channel number. All the existing controls are hardwired to talk
directly to channel 0.
There are a couple of limitations which we expect to apply to
multi-channel AGC. We're not allowing different frame durations to be
applied to the channels, nor are we allowing separate metering
modes. To be fair, supporting these things is not impossible, but
there are reasons why it may be tricky so they remain "TBD" for now.
This patch only includes the basic reorganisation and plumbing. It
does not yet update the important methods (switchMode, prepare and
process) to implement multi-channel AGC properly. This will appear in
a subsequent commit. For now, these functions are hard-coded just to
use channel 0, thereby preserving the existing behaviour.

Add a new helper function Histogram::interBinMean() that essentially
replaces the existing Histogram::interQuantileMean() logic but working on
bins instead.
Rework the interQuantileMean() to call into interBinMean() with the
appropriate convertion from quatiles to bins.

Usage of pip3 to install meson may result in a different meson version
available for the local user and for root. This causes issues when
running `meson install` (directly or through `ninja install`):
Installing to a system location will request elevated privileges and use
the system meson version to install files, which may fail to unpickle
data pickled with the meson version for the local user.
As all major distributions now provide a recent-enough version of meson,
usage of pip3 is not longer needed in most cases, and shouldn't be
recommended. Drop it.
While at it, update the version of meson listed in the documentation to
match the required version.

The Agc::process() function returns an AgcStatus object in the
metadata as before, but Agc::prepare() is changed to return the values
it computes in a separate AgcPrepareStatus object (under the new tag
"agc.prepare_status").
The "digitalGain" and "locked" fields are moved from AgcStatus to
AgcPrepareStatus.
This will be useful going forward as we can be more flexible about the
order in which prepare() and process() are called, without them
trampling on each other's results.

Sphinx 7.0.0 has dropped support for the deprecated 'style' variable
(https://github.com/sphinx-doc/sphinx/pull/11381). This breaks
compilation of the documentation:
/usr/bin/sphinx-build -D release=v0.1.0+16-eed6a079 -q -W -b html Documentation Documentation/html
Theme error:
An error happened in rendering the page api-html/index.
Reason: UndefinedError("'style' is undefined")
The recommended replacement is 'styles[-1]'. However, this resolves to
'_static/css/theme.css', which is part of the 'css_styles' variable, and
results in the stylesheet being included twice. To avoid that and fix
the compilation error, simply drop the first reference.

ABI Compliance:
abi-compliance-checker reports 99% binary compatibility and 81.4% source
compatibilty between version 0.0.5 and 0.1.
- Binary compatibility: 99%
- Source compatibility: 81.4%
- Total binary compatibility problems: 4, warnings: 2
- Total source compatibility problems: 165, warnings: 7
Now that we have funtional ABI validation, the soname has been updated from
libcamera.so.0.0.5 to libcamera.so.0.1.
Future releases will now maintain the same soname until an ABI breakage is
detected to reduce the repackaging and rebuilding of other components that may
use libcamera. The abi-compatibility report can now be generated with the new
utility './utils/abi-compat.sh'.
Key differences here are due to preventing the installation of internal and
private headers in the packaging process, and most of this API compatibility
should not be visible to applications with the exception of:
- Camera::generateConfiguration ( StreamRoles const& roles )
The StreamRoles type definition has been removed. This is now handled as a
Span<StreamRole> to prevent unnecessary allocations and copies.
- CameraManager::addCamera ( std::shared_ptr<struct Camera> camera, std::vector<unsigned long>const& devnums )
- CameraManager::get ( dev_t devnum )
- CameraManager::removeCamera ( std::shared_ptr<struct Camera> camera )
These functions of the CameraManager were for use exclusively by the V4L2
adaptation layer, and not intended for use by applications. This has now been
reworked to use the new SystemDevices and the redundant functions removed.
The ABI/API breakages have been introduced by:

The provider g_autoptr variable introduced by commit adb1bbb748a1
("tests: gstreamer: Test cameras' enumeration from GstDeviceProvider")
is left uninitialized when declared. The cleanup function could thus get
called on an unitialized variable if the scope was exited before the
variable gets initialized. This can't occur here, but gcc 8.4.0 still
complains about it:
/usr/include/glib-2.0/glib/gmacros.h: In member function ‘virtual int GstreamerDeviceProviderTest::run()’:
/usr/include/glib-2.0/glib/gmacros.h:1049:27: error: ‘provider’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

^
../test/gstreamer/gstreamer_device_provider_test.cpp:37:32: note: ‘provider’ was declared here
g_autoptr(GstDeviceProvider) provider;
Silence the error by initializing the variable to NULL at declaration
time. This is a good practice in any case, as later refactoring could
otherwise introduce a scope exit before initialization.

Handling ioctl's within applications is often wrapped with a helper such
as xioctl. Unfortunately, there are many instances of xioctl which
incorrectly handle the correct size of the ioctl request.
This leads to incorrect sign-extension of ioctl's which have bit-31 set,
and can cause values to be passed into the libcamera's v4l2 adaptation
layer which no longer represent the true IOCTL code.
Match the implementation of the Linux kernel and ensure that only 32
bits of the ioctl request are used by assigning to an unsigned int.

The imx708 must drop a single frame on startup - but only when in HDR
mode. Non-HDR modes do not need to drop frames. Fix the logic in
hideFramesModeSwitch() which currently unconditionally advertises to
drop one frame.
Unfortunately there is no clear way to tell if the sensor is in the HDR
mode. So for now, look the resolution and framerate to deduce this.
Additionally ensure we override hideFramesStartup() and return the same
number as hideFramesModeSwitch().

RPiCameraConfiguration::validate() did not account for user supplied
Bayer packing when validating the RAW stream configuration. Fix this
by seeing what packing (if any) has been specified selecting the output
RAW stream format.

New TI SoCs from J7 and AM62 family have a camera pipeline that receives
data using Cadence's DPHY-RX and CSI-RX bridge. A pixel-grabbing "shim"
IP routes this incoming stream of data to the DMA subsystem, to finally
store the frame data in memory.
The driver for this is not merged in mainline yet, but v7 was posted [1]
on linux-media list a few months ago.
With some minor fixes, the work-in-progress v8 series [2] works with the
simple pipeline handler, so we enable support for this device.

libcamera uses udev to support hotplug (and unplug) detection. This is
an optional feature, which gets selected automatically if udev is
available. Users may however want to build libcamera without hotplug
detection, even if udev is available on the system. Add a new feature
option to control udev support. The default value is auto, which retains
the existing behaviour.

The meson style, which libcamera follows, recommends a space before
colons in function parameters. Fix the style violations through the

The libcamera git history contains numerous examples of incorrect commit
message trailers due to invalid trailer types (e.g. Change-Id), typos
and other small issues. Those went unnoticed through reviews, which
shows that an automated checker is required.
Add a trailers checker to checkstyle.py to catch invalid or malformed
trailers, with a set of supported trailers that match libcamera's commit
message practices. New trailer keys can easily be added later as new
needs arise.

The commit title and commit ID are two different pieces of information.
Don't include the latter in the former, to simplify code that only needs
the commit title. Constructing a string from the ID and title is easier
than splitting the combined string back into its elements.

During development of the checkstyle.py script, it can be useful to run
only a subset of the checker. Add the ability to do so with a
'--checkers' command line argument.

When packaging libcamera, distributions may break IPA module signatures
if the packaging process strips binaries. This can be fixed by resigning
the modules, but the process is error-prone.
Add a command line ipa-verify utility that tests the signature on an IPA
module to help packagers. The tool takes a single argument, the path to
an IPA module shared object, and expects the signature file (.sign) to
be in the same directory.
In order to access the public key needed for signature verification, add
a static function to the IPAManager class. As the class is internal to
libcamera, this doesn't affect the public API.

libcamera creates a config.h file with predefined macros, and instructs
the compiler to include it implicitly with the -include argument.
Doxygen has no support for implicit inclusion of headers, but has a
PREDEFINED configuration option for its preprocessor that lists
predefined macros. Populate it with the values from the config_h
configuration data object that is used for generate the config.h file,
to ensure that documentation matches the configuration options libcamera
has been built with.
Bump the minimum meson version to 0.57 to use cfg_data.keys().
