Add support for SIOC[SG]80211BSSID, SIOC[SG]80211CHANNEL. 

Change the name of structure ieee80211_bss to ieee80211_node, which is
used for management of stations in hostap mode, and peers in ibss mode.
Split off ic_opmode, ic_phytype from ic_flags.
Preparation to merge 'wi' driver into 80211subr.c.
