Let's try to consolidate our documentation in doc/ in the repo. This includes some documentation from README.md, the HACKING.md coding style and the gitlab wiki. The README.md file now links to all top-level topics (i.e. not reachable via other topics). This also includes a few small changes to make things more consistent.

Commit Messages
Commit messages should follow the GNOME commit message
guidelines. We require an URL
to either an issue or a merge request in each commit. Try to always prefix
commit subjects with a relevant topic, such as compositor: or
clutter/actor:, and it's always better to write too much in the commit
message body than too little.
If a commit fixes an issue and that issue should be closed, add URL to it in
the bottom of the commit message and prefix with Closes:.
Do not add any Part-of: line, as that will be handled automatically when
merging.
The Fixes tag
If a commit fixes a regression caused by a particular commit, it can be marked
with the Fixes: tag. To produce such a tag, use
git show -s --pretty='format:Fixes: %h (\"%s\")' <COMMIT>
or create an alias
git config --global alias.fixes "show -s --pretty='format:Fixes: %h (\"%s\")'"
and then use
git fixes <COMMIT>
Example
compositor: Also consider dark matter when calculating paint volume
Ignoring dark matter when calculating the paint volume missed the case where
compositing happens in complete vacuum.
Fixes: 123abc123ab ("compositor: Calculate paint volume ourselves")
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1234
