Log message:
derived from NetBSD:

---
Make the node table into an LRU cache: least-recently used nodes
are at the end of the node queue.  Change the reference-counting
discipline: ni->ni_refcnt indicates how many times net80211 has
granted ni to the driver.  Every node in the table with ni_refcnt=0
is eligible to be garbage-collected.  The mere presence of a node
in the table does not any longer indicate its auth/assoc state;
nodes have a ni_state variable, now.

While I am here, patch ieee80211_find_node_for_beacon to do a "best
match" by bssid/ssid/channel, not a "perfect match."  This keeps
net80211 from caching duplicate nodes in the table.

ok deraadt@ dlg@, looks good jsg@
