mac80211: split off mesh handling entirely
This patch splits off mesh handling from the STA/IBSS.
Unfortunately it increases mesh code size a bit, but I
think it makes things clearer. The patch also reduces
per-interface run-time memory usage.
Also clean up a few places where ifdef is not required.
