WPS methods exported over DBus
I've exported the methods wpsPbc, wpsReg and wpsPin (patch attached), so wpa_supplicant should be able to connect with WPS using the dbus interface. I couldn't test it well because the problem seems to be in my wireless card, a Broadcom BCM4328. At least it seems to do the same using both interfaces. With ndiswrapper driver the "wpsie" entry (thanks Dan!) didn't appear, and with the Broadcom wl driver it appears but I cannot associate using WPS.
