* Enhance readability of some functions WRT node referencing by putting blocks around areas where node references are held
* Various bits of consistency of the usage of node references; always unreference them at the point at which they are no longer used. Don't reuse variables implicitly.
* Significant overhaul of the usage of bf_node and ieee80211_cb.ni. Always hold a reference with aforementioned variable and always unreference it properly.
