Clarify/fix handling of the current channel:

Clarify/fix handling of the current channel:
o add ic_curchan and use it uniformly for specifying the current
channel instead of overloading ic->ic_bss->ni_chan (or in some
drivers ic_ibss_chan)
o add ieee80211_scanparams structure to encapsulate scanning-related
state captured for rx frames
o move rx beacon+probe response frame handling into separate routines
o change beacon+probe response handling to treat the scan table
more like a scan cache--look for an existing entry before adding
a new one; this combined with ic_curchan use corrects handling of
stations that were previously found at a different channel
o move adhoc neighbor discovery by beacon+probe response frames to
a new ieee80211_add_neighbor routine

Cleanup beacon/listen interval handling:
o separate configured beacon interval from listen interval; this
avoids potential use of one value for the other (e.g. setting
powersavesleep to 0 clobbers the beacon interval used in hostap
or ibss mode)
o bounds check the beacon interval received in probe response and
beacon frames and drop frames with bogus settings; not clear
if we should instead clamp the value as any alteration would
result in mismatched sta+ap configuration and probably be more
confusing (don't want to log to the console but perhaps ok with
rate limiting)
o while here up max beacon interval to reflect WiFi standard

Fix handling of frames sent prior to a station being authorized
when operating in ap mode. Previously we allocated a node from the
station table, sent the frame (using the node), then released the
reference that "held the frame in the table". But while the frame
was in flight the node might be reclaimed which could lead to
problems. The solution is to add an ieee80211_tmp_node routine
that crafts a node that does exist in a table and so isn't ever
reclaimed; it exists only so long as the associated frame is in flight.
