While we're at it, I believe there are a number of ways to improve
ahcpd, most notably:

- allow to configure everything from the configuration file, the way
  it is now done with babeld;

- if the server's own addresses intersect with the distributed
  prefixes, don't attribute them to someone else.  It's not that easy
  to implement (maybe also through netlink? Does it allow to monitor
  addresses being added/deleted?);

- read a configuration file by default without having to specify a
  "-c" option, the way it is done with babeld.

It looks like something to keep for the upcoming Babel hackathon,
isn't it?
