mac80211: Introduce a generic commit() to apply changes
This patch introduces a generic commit() function which initiate a new network joining process. It should be called after some interface config changes, so that the changes get applied more cleanly. Currently set_ssid() and set_bssid() call it. Others can be added in future patches. In version 1 the header files was forgotten, sorry.
