- Add logging to init script
- Add delay so OpenRC realises if we crashed quickly b/c of e.g. bad config
   file
- General cleanups (like supporting multiple instances, style changes)

This should make it a lot easier to see what's going wrong when something
breaks.

Written originally for Gentoo but should work
on Alpine and other OpenRC-consuming distros too.

Handle the case where atheme had a successor, but didn't correctly
elect them as founder (?)

This makes invoking the script multiple times with the same input return
the same result, which may not be the case before because sets are
unordered and thus the channel modes can become reordered across
multiple invocations of the script.

For example, if the mlock is set to `-i`, `i` is not present in the
`modes` and thus it would error.

I'm inclined to think that the negative mlock feature doesn't behave
correctly, because the mlock of `-i` (or `-n`) would prevent anyone from
ever setting those modes on the channel. Which this does not appear to
be the case.

Fixes #1401

-P/--publish-all publishes the container ports on a random
host port, which you have to look up using `docker port`.

In the common case they should be published on the same ports.

This will allow easier building on docker hub and let us automatically
publish tags for each release.
