[arch-general] netcfg v2.1

[James Rayner]

netcfg v2.1 is mostly a bug fix release, however there are some
important changes and new features.

- Remove driver specific hacks/quirks. They now need to be enabled
manually using the QUIRKS=() array.
- auto-wireless has been moved from net-profiles to a separate daemon net-auto.
- A new option (IWCONFIG) to run iwconfig with set arguments before connecting
- Various minor fixes

Details can be found on the wiki for all these options
