add support for getting the current policy setting and collecting
the list of mac addresses in the acl table.

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

or a bssid+ssid. This is needed for later versions of wpa_supplicant
and for forthcoming addons to wpa_supplicant.
Note this is an api change and applications must be rebuilt.
we're at it:
o WPA/802.11i has a unicast key and a group key; in station mode
everything is sent with the unicast key--we were consulting the
destination mac address and incorrectly using the group key
o (perpetuate fallback use of the default tx key to maintain
compatibility with the way wpa_supplicant works)
o correct EAPOL encryption logic to check unicast key instead
of assuming other state implies this
o move QoS encapsulation up to before enmic work so TKIP has the
information required to calculate the pseudo-header
o do not do QoS-encapsulation of EAPOL frames as some ap's do the
wrong thing with such frames (may need to revisit this if ap's
start dropping non-QoS frames from stations assoc'd with QoS)
o move ieee80211_mbuf_adjust closer to its caller
here but it includes completed 802.11g, WPA, 802.11i, 802.1x, WME/WMM,
AP-side power-save, crypto plugin framework, authenticator plugin framework,
and access control plugin frameowrk.
o code reorg (relative to old netbsd-derived code) for future growth
o drivers now specify available channels and rates and 802.11 layer handles
almost all ifmedia actions
o multi-mode support for 11a/b/g devices
o 11g protocol additions (incomplete)
o new element id additions (for other than 11g)
o node/station table redone for proper locking and to eliminate driver
incestuousness
o split device flags and capabilities to reduce confusion and provide room
for expansion
o incomplete power management infrastructure (need to revisit)
o incomplete hooks for software retry
o more...
