Android HAL adaptation layer may need image processing, for
example, scaling and format conversion. Libyuv is a general image
processing. This adds libyuv to subprojects, so that it is forked
locally and can be used with Android HAL implementation code.

Implement tracing infrastructure in libcamera. It takes .tp files, as
required by lttng, and generates a tracepoint header and C file, as lttng
requires. meson is updated accordingly to get it to compile with the
rest of libcamera. Update the documentation accordingly.

Version 0.51 allows, among others, checking for python modules, which is
a required feature.
It is also now easily accessible: it is in stable distros such as Debian
testing, or in pip:

pkg-config it is not only used to detect libudev-dev, it is used for
detecting gstreamer and others. So it is more correct to place it on the
Meson Build system section.

All the dependencies are for libcamera, so we should move all the

second one for python3-yaml. I think the later is more clear.

This is needed to use option type 'feature'. This is a tri-state
(auto/enabled/disabled) which comes with utility to enable them all, or
disabled them all to avoid any dynamic selection happening. It can also
be used as value to any "required" field.
This will be used in GStreamer support. If you don't have a recent enough
meson in your distribution, you can always install or upgrade your version
using pip3.
pip3 install --user meson
pip3 install --user --upgrade meson

The Getting Started information makes little sense on the generated
documentation, as a developer with documentation compiled from a local
libcamera source tree has already got started. We however want to keep
the information in the top-level README.rst as it is useful there.
In order to hide the Getting Started information from the front page
while keeping it in README.rst, add comments to delimitate sections of
README.rst, and include only a subset of the file in the front page.

Bring back auto-generation of control ids. In this version, both the
header and the source files are generated from a single YAML file that
stores all control definitions. This allows centralising controls in a
single file, while the previous version required keeping both
declarations (in a header) and documentation (in a the source) in sync
manually.
Using YAML as a format to store control definitions is a trade-off
between ease of use (there are many YAML parsers available) and
simplicity (XML was considered, but would have lead to more complex
processing). A new build time dependency is added on python3-yaml, which
should be available as a package in all distributions and build
environments.
The YAML format is likely to change over time as we improve
documentation of controls, the first version simply copies the
information currently available. Future improvements should also include
a YAML schema to validate the YAML source file.

The Documentation and top-level README both serve to provide information
to new developers and users of libcamera.
Currently our README.md is sparse, and should be expanded with more
useful information such as build requirements as well as compilation
directions.
Any information provided in the README also serves a purpose in the main
documentation and website and could be a cause of duplicated content.
To allow direct integration of the top level README document into our
sphinx documentation (and thus the libcamera.org website) convert the
README.md into ReSTructured text format.
