UNRELEASED should not be left as-is when actually releasing.
The latest changelog entry now point at unstable instead.

The simple d/genchangelog.sh now does `dch -r ''` automatically
to ensure this distribution update doesn't get lost along the way
on future invocations.

I am still not sure what to propose for organizing this better across
multiple projects. In our organization we use `repo` by Google,
originally intended for syncing Android repositories, so that we track
multiple repositories that belong together while avoiding mono-repos.

It uses a default.xml manifest file in a dedicated "manifest" repo,
which then just lists which repositories should be pulled in.

Command/tool ref: https://source.android.com/setup/develop/repo
Manifest file ref: https://gerrit.googlesource.com/git-repo/+/master/docs/manifest-format.md

A sample manifest, which should do the trick, could be:

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
  <remote name="origin"
    fetch="https://git.ipfire.org/pub/git/"
    pushurl="ssh://people.ipfire.org/pub/git/" />
  <default remote="origin" revision="master" />

  <project name="location/libloc" />
  <project name="location/location-database" />
</manifest>
