Fix race condition in handling node reference counts for authenticating
stations in ap mode. Track when a node's first auth frame is
received and use this to decide whether or not to bump the refcnt.
This insures we only ever bump the refcnt once.

mark stations authorized during recv processing instead of doing it
as a side effect of sending an auth success frame; sending mgmt
frames should not have side effects

accept diassoc frame in ASSOC state

pull some debug msgs up so they're seen more often

kick the state machine when we receive failure notice from an ap (when
operating in sta mode); this speeds up the state machine, previously
we were acting on a timeout

discard open auth requests in adhoc mode

reject open auth requests when shared key auth is configured

add ieee80211_send_error to encapsulate an idiom

don't reject station based on the PRIVACY bit in the capabilities;

correct checks for rate set compatibility

record tstamp from beacons received in station mode when associated;
this is needed by drivers that want to resync their timers based on

can better program beacon timers
