This patch release commences the package release procedures for the
project.
Initial releases will include a bump to the patch (0.0.x) version
number, as well as a corresponding increment to the soname.

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.

The bytesused value for the parameters buffer is initialized to 0 and
never set. The V4L2 API specification indicates that, for an output
video device, the driver will set the bytesused value to the size of the
plane in that case. The videobuf2 framework does so, but considers this
as deprecated and prints a warning:
[ 54.375534] use of bytesused == 0 is deprecated and will be removed in the future,
[ 54.388026] use the actual size instead.
Fix it by setting bytesused to the correct value before queuing the

Private members of the FrameBuffer class are split between FrameBuffer
and FrameBuffer::Private. There was no real justification for this
split, and keeping some members private in the FrameBuffer class causes
multiple issues:
- Future modifications of the FrameBuffer class without breaking the ABI
may be more difficult.
- Mutable access to members that should not be modified by applications
require a friend statement, or going through the Private class.
Move all remaining private members to the Private class to address the
first issue, and add a Private::metadata() function to address the
second problem.

utils::defopt causes compilation issues on gcc 8.0.0 to gcc 8.3.0,
likely due to bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86521
that was fixed in gcc 8.4.0. gcc 8.3.0 may be considered old (libcamera
requires gcc-8 or newer), but it is shipped by Debian 10 that has LTS
support until mid-2024.
As no workaround has been found to fix compilation on gcc 8.3.0 while
still retaining the functionality of utils::defopt, remove it from the
libcamera base library. This change could be reverted once support for
gcc-8 will be dropped.

Commit 09c1b081baa2 ("libcamera: controls: Generate and use fixed-sized
Span types") added explicit Span casts for fixed extent spans that were
required due to the ControlList::set() function that takes an
std::initializer_list not being able to infer a control size from
template arguments. This has now been fixed, so the casts are not needed
anymore. Drop them.

The ControlList::set() function overload used for array controls
constructs a Span from an initializer list. It doesn't specify the Span
size explicitly, which results in a dynamic extent Span being
constructed. That causes a compilation failure for fixed-size array
controls, as they are defined as Control<T> with T being a fixed-extent
Span, and conversion from a dynamic-extent to fixed-extent Span when
calling ControlValue::set() can't be implicit.
Fix this by constructing the Span using the size of the control, which
resolves to a fixed-extent and dynamic-extent Span for fixed-size and
dynamic-size array controls respectively. The ControlList::set()
function that takes an initializer list can then be used for fixed-size
array controls.

Array controls specify the array size through the YAML 'size' element,
which stores a list of values, one per dimension. Variable-size arrays
currently use an empty 'size' list, which prevents describing the number
of dimensions of the array.
Improve this by using the same notation for fixed-size and variable-size
array controls. Dimensions that are not fixed are described as a string
instead of an integer, such as [n], [n,3] or [w,h]. The strings have
currently no special meaning, this may change in the future.

The gen-controls.py script handles the data structure produced by the

The IPAFrameContext documentation has a spurious Doxygen \struct
statement that is not needed, and uses a \struct instead of a \var in
another location. Fix both issues. This doesn't cause any change in the
generated documentation.
Note that the Doxygen output for IPAFrameContext is incorrect,
documentation is missing for all members. This is caused by using "."
instead of "::" in our documentation, which we currently do because the
correct syntax produces Doxygen warnings (and still incorrect output).
