Rename powerd to something less generic

[Jeremy Bícha]

powerd is the name of an already existing binary package in Debian. I guess it wasn't noticed since it's part of freebsd-utils which
was apparently never really in Ubuntu.

This could be a problem if this package is ever submitted for inclusion in Debian. And it's just confusing if someone tries to Google for more information or troubleshooting a problem and just assumes that FreeBSD is upstream, not Canonical.

Jack, please try to give a reason when closing bugs. In this case, I believe the bug is valid; it's just a question of whether Canonical wants to fix it. If they do want to fix it, it's a little easier to do it now before 13.10 is released

Steve could you offer an opinion on whether we should rename?

[Steve Langasek (vorlon)]

Given that the powerd package in Debian is freebsd-specific and will therefore never be in Ubuntu, and the Ubuntu powerd will never be ported to BSD, I don't think the name conflict is significant. It's certainly allowed to have a single binary package name provided by different source packages on different architectures.

If someone had a good replacement name for this and upstream were inclined to accept the rename, then that's fine; but the obvious choice ('upower') is taken by another package already (calling it 'upowerd' rather than 'upower' would be no less confusing), and I don't see the value in forcing an arbitrary rename here.
