Object ownership is a complex topic that can lead to many issues, from
memory leak to crashes. Document the rules that libcamera enforces to
make object ownership tracking explicit.
This is a first version of the rules and is expected to be expanded as
the library is developed.

Add the move semantics (move constructor and move assignment) to the
allowed C++11 features, as we extensively use them for the unique and
shared pointers.

The pipeline handlers don't define APIs, neither public not internal.
There is thus no need to generate Doxygen documentation from thoses
classes. Add them to the EXCLUDE files pattern.

The output of the sphinx-build for our documentation is overly verbose.
Reduce this output to warnings and errors with the '-q' quiet option.

Until we have better Sphinx + Doxygen integration, replace the relative
external link to the API documentation with a placeholder directory,
which will be populated with the Doxygen-generated doc when exporting
documentation to the website. This is needed as the Sphinx documentation
is exported to the root of the website, linking to ../api-html is thus
not possible.

Add a link in the toctree to the API documentation.
sphinx doesn't seem to support relative external links, but we can trick
it into thinking the link is absolute by adding '#://' at the end.

The toctree is displayed in the navigation bar at the top of the page.
Add short names to the entries that replicate the names currently used
on libcamera.org.
Remove the link to the index and search pages, as the former is empty,
and the latter can be accessed directory from the navigation bar search
box.

Extend the documentation build system to automatically generate
documentation from source code using Doxygen. This is currently separate
from the sphinx documentation, and should be integrated using the
breathe (and possibly exhale) extensions.
As the Documentation/meson.build file needs to reference the variables
holding the source files, move the Documentation directory to the end of
the subdirs() in the top-level meson.build.

Use the datadir option to select the directory in which to install
documentation. This defaults to $prefix/share so this doesn't introduce
any change in the default case.
While at it use join_paths() to join patch components instead of
hardcoding the / separator.
