Add a local patch for fully-locked system accounts. Need to investigate
if there is a way to add the exclamation mark dynamically according to
the systemd version.

buildbot-contrib is merged back to the main repo
https://github.com/buildbot/buildbot/pull/8035

* The checksum of buildbot-contrib-systemd-common.patch is changed after
  upstream force-pushed to the pull request. As it is now merged,
  backporting my patch is no longer necessary.
* Switch back to git sources, now that pacman is fixed and released
* Skip tests not used by upstream
* Drop PGP keys for inactive contributors and avoid email addresses

Closes issue #1, as the cgi fix is part of upstream 3.11.9:
https://github.com/buildbot/buildbot/pull/8112

The checksum of buildbot-contrib-systemd-common.patch is changed after
upstream force-pushed to the pull request. As it is now merged,
backporting my patch is no longer necessary

* Switch back to git sources, now that pacman is fixed and released
* Skip tests not used by upstream
* Drop  --openssl-legacy-provider. That is a workaround for older
  webpack, which is not used by react-based frontend

* python-sqlalchemy1.4 is still needed as upstream fixes for sqlalchemy
  2.x are in git-master only, not backported yet [1].
* Drop *react* packages. All frontend packages use React, so *react*
  packages are duplicates.
* Move to PEP 517 following upstream [2]. The egg_info hack is broken
  since [3] and no longer needed.
* python-importlib_resources not needed for newer Python since [4]
* python-six no longer needed. 3.11 branch moved from python-future to
  python-six [5], and python-future is not needed anymore [6].
* Drop PGP keys for inactive contributors and avoid email addresses

Use versioned deps to make sure all relevant packages are upgraded
together. This is a preparation for buildbot 4.x, where react plugins
will not be packaged anymore. At that time, users need to uninstall
react plugins to upgrade all buildbot packages.

See: https://archlinux.org/todo/python-sqlalchemy-2-rebuild/

Partially revert changes made for 3.11.1-1
(4e3a2feb)

Also updates .nvchecker.toml to exclude 4.x

Sometimes PyPI releases are a little bit delayed

Not using PYTHONWARNINGS as it breaks some tests, which check stderr
from child processes

Prepare for:
#1

Due to a pacman issue [1], the checksum is unstable

I have verified that the checksum change is only related to
`export-subst` mentioned in the pacman issue. No other changes are
involved, and supply-chain attacks are unlikely.

[1] pacman/pacman#131

* python-packaging: needed since [1], which is actually already in
  3.10.0
* python-six: replaces python-future since [2]

Also switches from signed tarballs to signed git tags

* Add python-buildbot-react-waterfall-view, which has been there in 3.9
  [1]
* python-unidiff is now a required dependency [2]
* python-croniter needed since [3]
* python-setuptools is replaced by importlib_resources in [4]. I
  proposed to further replace importlib_resources with
  importlib.resources in [5].

Dropping python310.diff as the PR for Python 3.11 [1] also includes
fixes for Python 3.10.
