Hello,

I've attached a patch that adds two autopkgtests to the package. One is
very simple and checks that the as-installed examples can be compiled,
but doesn't run them.

The other test installs Prosody, configures it to enable in-band
registration, and creates and deletes a user. Although the code may be
a little bit more ugly, I think it's worth it for a test that tests a
server as well.

I ran both tests under QEMU and they pass as-is for the unstable and
experimental packages.

I've spruced up the patch a little bit and and made it work on systems
not running systemd. The new patch which may be applied with 'git am'
to debian/experimental is attached

Forgot to close the bug in the changelog entry...
