[arch-dev-public] [signoff] wpa_supplicant 0.6.8-1

wpa_supplicant declared the 0.6 branch as stable, changes compared to the old version are: - Disabled prism54, hostap, madwifi and IPW drivers, these should all be obsolete and work with the "wext" driver. If any problems occur, I can enable them again, but I think having only wext is enough. - Enabled the new nl80211 driver. This has additional features over the wext driver, like setting the country code (this driver currently only works with compat-wireless or maybe 2.6.29 release candidates) - Enabled readline support for wpa_cli - Enabled WPS (WiFi protected setup), I don't know if anyone really wants that, but it is there now. wpa_supplicant_gui has also been considerably improved. Please sign off.
