The HAL config file is assumed to be in the LIBCAMERA_SYSCONF_DIR
directory, which is defined by the meson build system at compile time.
As the filesystem layout on Android installations might be device/build
specific, allow to override such assumption using the
LIBCAMERA_HAL_CONFIG_PATH environment variable and document its usage.
While at it, remove quotes from the error message, as the file path
doesn't contain any space.

The CameraSensor class validates that the sensor driver in use supports
the controls required for IPA modules to work correctly.
For in-tree IPA modules, whose pipeline handlers already use
CameraSensor there's no need to validate such controls again.
Remove controls validation from the IPU3 and RkISP1 IPA modules and rely
on CameraSensor doing that at initialization time.
The list of mandatory controls is expanded to add V4L2_CID_ANALOGUE_GAIN
without which IPA modules cannot function.
The new requirement only applies to RAW sensors, platforms like UVC and
Simple are not impacted by this change.
While at it, expand the sensor driver requirements documentation to
include V4L2_ANALOGUE_GAIN in the list of mandatory controls a sensor
driver has to support.

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.

Align the style of Doxyfile.in with the `doxygen -g` output, to minimize
diffs in the future when updating the file with `doxygen -u`. This
includes
- Replacing tabs with spaces
- Replacing += with \ to continue lines
- Dropping the \ on the last line of an option
Also update the Doxygen version number to indicate that the file has
been updated to v1.9.5, even if no modification to the options in use
were needed.

Doxyfile.in was generated using `doxygen -g` with Doxygen v1.8.14. This
has produced a file with all options supported by Doxygen at the time,
and a handful of them have then been modified to support libcamera's
needs, with most options retaining their default.
Some of the default options have been deprecated in newer Doxygen
releases, which led to warnings when generating the documentation. The
usual process to fix this is to update the configuration file with
`doxygen -u`. This creates a big diff due to the large number of changes
to default options, which isn't quite nice. Instead, let's just drop all
the default options and the comments, to produce a small and more
readable Doxyfile.in.

This is a partial revert of commit 395d43d6d75b ("libcamera:
v4l2_videodevice: Drop toV4L2PixelFormat()")
The function was removed because it incorrectly maps non-contiguous V4L2
format variants (ie V4L2_PIX_FMT_YUV420M) to the API version supported
by the video device (singleplanar API and multiplanar API). It was
decided at the time to remove the function and let its users call
directly V4L2PixelFormat::fromPixelFormat() which accepts a
'multiplanar' flags.
As we aim to associate multiple V4L2PixelFormat to a single libcamera
format, the next patches will verify which of them is actually supported
by the video device. For now, return the contiguous version
unconditionally.
Re-introduce V4L2VideoDevice::toV4L2PixelFormat() and convert all
the V4L2PixelFormat::fromPixelFormat() users to use it.
The V4L2 compatibility layer is the only outlier as it doesn't have a
video device to poke, hence it still uses
V4L2PixelFormat::fromPixelFormat().
Next patches will implement the device format matching logic and handle
the non-contiguous plane issue in V4L2VideoDevice::toV4L2PixelFormat().

In order to allow dynamic instantiation of algorithms based on tuning
data files, add a mechanism to register algorithms with the IPA module.
The implementation relies on an AlgorithmFactory class and a
registration macro, similar to the pipeline handler registration
mechanism. The main difference is that the algorithm registration and
instantiation are implemented in the Module class instead of the
AlgorithmFactory class, making the factory an internal implementation
detail.

The V4L2VideoDevice::toV4L2PixelFormat() function is incorrectly
implemented, as it will pick a multi-planar format if the device
supports the multi-planar API, even if only single-planar formats are
supported. This currently works because the implementation calls
V4L2PixelFormat::fromPixelFormat(), which ignores the multiplanar
argument and always returns a single-planar format.
Fixing this isn't trivial. As we don't need to support multi-planar V4L2
formats at this point, drop the function instead of pretending
everything is fine, and call V4L2PixelFormat::fromPixelFormat() directly
from pipeline handlers. As the single-planar case is the most common,
set the multiplanar argument to false by default to avoid long lines.

connections to Object instances).
Add a BoundMethodFunctor class to bind a functor, and a corresponding
Signal::connect() function. There is no corresponding disconnect()
function, as a lambda passed to connect() can't be later passed to
disconnect(). Disconnection typically uses disconnect(T *object), which
