Those are really part of the OS, they are not meant to be flatpaks

The Autotools build was dropped from master.

This tarball is old enough to be in all current LTS distros

The git tag tarball generated by github has changed. Since there exist
no official tarballs for libgit2 just update the checksum for now..

this is the name of the repo and the release folder

See https://gitlab.gnome.org/GNOME/gnome-usage

So we can finally remove libgda-5.2 from modulesets.

Keep the conditional dependencies at the tail of the list.

Make use of the recently added ability to rename tarballs because the
names of brotli v1.0.1 and woff2 v1.0.1 tarballs are the same.

Modules hosted on GitHub have autogenerated tarball names coming from
the release tag. This means a lot of them have unhelpful names like
'v1.0.1.tar.gz', or '296.zip'.

If two different modules have the same tag, we end up with a collision
when trying to check that the tarball downloaded have the same checksum.

We can add a simple XML attribute that allows us to rename the tarball
if that's the case; we can also throw in variables support for the name
of the module and the version, which will hopefully help us to avoid
collisions.
