[arch-projects] [netctl] Time to move

[Jouke Witteveen]

With the final initscripts deprecation warning on the site, I think we
should not wait much longer pushing netctl, the systemd reincarnation
of netcfg.
Here's what needs to be done:

- move openresolv to [core]
- add netctl to [testing]

later:
- add netctl to [core]
- announce the deprecation of netcfg on the site and ask people to
migrate manually (with a howto)
- remove netcfg from [core]
- possibly: add netctl to the base group

@Florian Pritz: would you like to maintain the netctl packages as you
did with the netcfg package?

Regards,
