Add a pipeline handler for the Mali-C55 ISP.
The pipeline doesn't currently support an IPA and does not run
any 3a algorithm but only handles the media graph topology and
formats/sizes configuration

Meson uses tags to sort installed files in categories, and makes it
possible to install a subset of the files using the '--tags' argument to
'meson install'. This is typically used by distributions to split the
runtime, development and documentation files into separate packages.
By default, meson tries to guess the correct tag for installed files,
but can't always do so properly. Mark the install targets that meson
can't guess with the correct install_tag.
As the feature has been introduced in meson 0.60, bump the minimum meson
version. The latest LTS release of all major distributions that
libcamera currently targets ship a recent enough meson version.

Add support for using separate YAML files for controls and properties
generation. The mapping of vendor/pipeline handler to control file is
done through the controls_map variable in include/libcamera/meson.build.
This simplifies management of vendor control definitions and avoids
possible merge conflicts when changing the control_ids.yaml file for
core and draft controls. With this change, libcamera and draft controls
and properties files are designated the 'libcamera' vendor tag.
In this change, we also rename control_ids.yaml -> control_ids_core.yaml
and property_ids.yaml -> property_ids_core.yaml to designate these as
core libcamera controls.

Use the compiler.get_define() function to get the value of
_FORTIFY_SOURCE instead of iterating over the cpp_args. This simplies
the code, but also guarantees to return the actual value of
_FORTIFY_SOURCE, even if defined through other means than through the
meson cpp_args.

ChromeOS is moving to a platform default of `_FORTIFY_SOURCE=3`, and
this definition conflicts with that:
<command line>:4:9: error: '_FORTIFY_SOURCE' macro redefined
[-Werror,-Wmacro-redefined]
Rather than adding logic to keep up with their local configuration, it
seems best to leave setting _FORTIFY_SOURCE on ChromeOS up to ChromeOS.

The meson find_library() function takes a library name without the "lib"
prefix. Its usage to find lic++ is thus not correct, and meson warns
about it:
WARNING: find_library('libc++') starting in "lib" only works by accident and is not portable
Fix it by dropping the "lib" prefix.

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:
5ca0c9276f28 ("libcamera: CameraManager: Remove ::get(dev_t)")

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.

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,

Now that we identify ABI breakages, provide incremental releases which
can support backwards compatible linkage across release points that have
a compatible ABI.
Introduction of this commit does not convey that libcamera now has a
stable API, but that patch releases with a common minor number
(0.minor.patch) may potentially be used by applications without
recompilation and linkage against new releases.

Split the Raspberry Pi pipeline handler and IPA source code into common
and VC4/BCM2835 specific file structures.
For the pipeline handler, the common code files now live in
src/libcamera/pipeline/rpi/common/
and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/.
For the IPA, the common code files now live in
src/ipa/rpi/{cam_helper,controller}/
and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the
camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/.
To build the pipeline and IPA, the meson configuration options have now
changed from "raspberrypi" to "rpi/vc4":
meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4

The current IPA build files require a flat directory structure for the
IPAs. Modify the build files to remove this restriction and allow a
directory structure such as:
src/ipa
|- raspberrypi
|- common
|- cam_helpers
|- controller
|- vc4
|- rkisp1
|- ipu3
where each subdir (e.g. raspberrypi/common, raspberrypi/cam_helper) has
its own meson.build file. Such a directory structure will be introduced
for the Raspberry Pi IPA in a future commit.

Starting from 13.1, gcc implements the C++23 version of automatic move
from local variables in return statements (see
https://en.cppreference.com/w/cpp/language/return). As a result, some
previously required explicit `std::move()` in return statements generate
warnings. This is the case when a function returns an object whose type
is a class derived from the class type the function returns:
struct U { };
struct T : U { };
U f()
{
T t;
return t;
}
Up to C++20, the automatic move from local variables selects the move
constructor of class U, which is not the move constructor of the
expression. Overload resolution is then performed a second time, with t
considered as an lvalue. An explicit `std::move(t)` is needed in the
return statement to select the U move constructor.
Starting from C++23, `t` is treated as an xvalue, and the U move
constructor is selected without the need for an explicit `std::move(t)`.
An explicit `std:move()` then generates a redundant-move warning, as in
the valueOrTuple() function in src/py/libcamera/py_helpers.cpp.
Omitting the `std::move()` silences the warning, but selects the copy
constructor of U with older gcc versions and with clang, which
negatively impacts performance.
The easiest fix is to disable the warning. With -Wpessimizing-move
enabled, the compiler will still warn of pessimizing moves, only the
redundant but not pessimizing moves will be ignored.

The previous attempt to fix git version parsing in commit d34cefad1791
("meson: Fix git version parsing") was too naive, and didn't take into
account cases where the libcamera git version contains no or multiple
'+' signs.
Fixing this is more complex than a one-liner change, as meson doesn't
support Python-style slicing of arrays or a length method on strings.
The simplest and most versatile option is to patch the version string in
the gen-version.sh script. Do so, and clarify the comments related to
version handling in meson.build.

When extracting the build metadata from the git version, we use the
string strip() method to remove the version prefix. This is incorrect,
as the strip() method takes a set of characters to be removed, not a
literal string. Fix it by splitting the git version string on the '+'
character and keeping the suffix.

The build metadata is split off correctly from the version string

this step is not carried out. However, since libcamera uses Semantic

The supported pipelines are listed in three places: the
meson_options.txt file, the defined array when a user selects
-Dpipelines="all", and arrays defined when the default
-Dpipelines="auto" is selected.
This can be hard to maintain and error prone.
Rework the definition of pipeline selection to a single table which
specifies the architecture(s) that the pipeline handler supports and
iterate it to handle the special cases for 'all', 'auto' and 'test'.
The current behaviour such that 'all' takes precedence over 'auto' is
maintained, and 'test' is now extended such that additional test
pipeline handlers can easily be introduced.
The existing implementation defines the i.MX8-ISI and RKISP1 pipeline
handlers as only supported by 'aarch64'. This conversion changes the
behaviour such that those pipeline handlers are now supported on both
'arm' and 'aarch64' as each of those platforms could support a 32-bit
ARM build.

Not all C libraries include support for locale objects (locale_t) and
the strto*_l() family of functions. A notable example is uClibc that can
be compiled with a hardcoded "C" locale. Compilation then fails as the
newlocale(), freelocale() and strtod_l() functions are not defined.
Fix the compilation breakage by checking for the availability of the
locale_t type, and fall back to strtod() when the type isn't available.
This may not lead to the correct result if support for locale objects
isn't available and the locale isn't hardcoded to "C", but that is such
a corner case that we will likely never encounter it.

only the pipeline handlers that will be used for the given architecture.
Let's do that by default now, but still allow to build the other

example, on a x86-64 platform:

Meson introduces a .replace() method in version 0.58.0. However we aim
to restrict ourselves to 0.56 meson features, as released by Debian
stable.
The recent introduction of release management infrastructure makes use
of the .replace() method to fix up the version string when there is a
mis-match between the release version and any (lack) of tags in the git
version description. This breaks when built on systems with only meson
0.56.
Refactor this to use a concatenation of the project version and a
stripped git version to regenerate the full source version string that
will be reported by libcamera.

The libcamera project is not yet ready to declare ABI nor API stability,
but it will benefit the community to be able to provide more regular
release cycles to determine 'versioned' points of history.
Ideally, these releases will be made at any ABI breakage, but can be
made at arbitary time based points along the way.
To support releases which may not be ABI stable, declare the soversion
of both the libcamera and libcamera-base library to be dependant upon
both the major minor and patch component of the project version.
As part of this, introduce a new 'Versions' summary section to highlight
the different version components that may become apparent within any
given build.
Bumping versions may leave dangling libcamera.so.* symlinks in build
directories. This will confuse Doxygen which will print during its
directory scanning phase a warning that the symlink can't be read. As we
don't need Doxygen to follow symlinks, disable it with EXCLUDE_SYMLINKS.

It's not safe to assume `-include config.h` works, since this depends on
the functionality of the compiler that the cwd when running the compiler
is searched first.
When libcamera is included as a Meson subproject, the cwd of the
compiler is the cwd of the main project, not of libcamera's build dir,
and thus cannot be found. Instead, pass the include filename as a path

Building the libcamera Android layer currently makes use of features
from meson 0.55. The core libcamera framework in the default configuration
without android enabled uses the 'summary' feature available in 0.53, and
is the lowest supportable meson version if the Android HAL is excluded.
Ubuntu 20.04 LTS currently provides meson 0.53 and represents an
acceptable minimum version to support. Platforms utilising the Android
component will have full control over their build environment and can
ensure that they provide a more recent version of meson.
Reduce the supported meson version for the project to 0.53 to facilitate
building on more distributions without having to manually update the
meson package.
Meson will output a warning that features not available in 0.53 are used
if the Android HAL is enabled. This is considered as an acceptable
middleground to improve the experience on the latest Ubuntu LTS, until
22.04 LTS is released and provides a newer meson version.

When distributions build and package libcamera libraries, they may not
necessarily run the build in the upstream source tree. In these cases, the git
SHA1 versioning information will be lost.
This change addresses that problem by requiring package managers to run
'meson dist' to create a tarball of the source files and build from there.
On runing 'meson dist', the utils/run-dist.sh script will create a
.tarball-version file in the release tarball with the version string generated
from the existing utils/gen-version.sh script.
The utils/gen-version.sh script has been updated to check for the presence of
this .tarball-version file and read the version string from it instead of
creating one.

The gen-version.sh script expects to be called from a git repo, and sets its

from a tarball source - full support for which is in a future commit.
The MESON_SOURCE_ROOT environnement variable does not get set when called from
the meson vcs_tag() function, but does when called from the run_command()
function, so that cannot be used either.
Instead, explicitly pass the meson source root to the gen-version.sh script.

- configure which is called when IPA is configured only
- prepare called on EventFillParams event at each frame when the request
is queued
- process called on EventStatReady event at each frame completion when
the statistics have been generated.
The existing AGC implementation already has a function named process(),
though it has different arguments. Adding the new virtual process()
interface causes a compiler warning due to the AGC implementation
overloading a virtual function, even though the overload can be resolved
correctly.
Temporarily disable the warning in this commit to maintain bisection
