indicates if an association id is required before outbound traffic
is permitted. This cleans up the previous change that broke mcast
traffic "to the stack" in ap mode as a side effect.

capabilities reported by the ap. These need to be cross-checked
against the local configuration in the vap. Previously we were
only checking the ap capabilities which meant that if an ap reported
it was ff-capable but we were not setup to use them we'd try to do
ff aggregation and drop the frame.
There are a number of problems to be fixed here but applying this
fix immediately as the problem causes all traffic to stop (and has
not workaround).

o change ieee80211_parse_htcap and ieee80211_parse_htinfo to save only
internal state obtained from the ie's; no dynamic state such as
ni_chw is altered
o add ieee80211_ht_updateparams to parse ht cap+info ie's and update
dynamic node state
o change ieee80211_ht_node_init to not take an htcap ie that is parsed;
instead have the caller make a separate call as one caller wants to
parse the ie while another wants to parse both cap+info ie's and
update state so can better do this with ieee80211_ht_updateparams
These changes fix sta mode state handling where the node's channel
width was shifted to ht20/ht40 prematurely.
For receive:
o explicitly tag rx frames w/ M_AMPDU instead of passing frames through
the reorder processing according to the node having HT and the frame
being QoS data
o relax ieee80211_ampdu_reorder asserts to allow any frame to be passed
in, unsuitable frames are returned to the caller for normal processing;
this permits drivers that cannot inspect the PLCP to mark all data
frames as potential ampdu candidates with only a small penalty
o add M_AMPDU_MPDU to identify frames resubmitted from the reorder q
For transmit:
o tag aggregation candidates with M_AMPDU_MPDU
o fix the QoS ack policy set in ampdu subframes; we only support immediate
BA streams which should be marked for "normal ack" to get implicit block
ack behaviour; interestingly certain vendor parts BA'd frames with the
11e BA ack policy set
o do not assign a sequence # to aggregation candidates; this must be done
when frames are submitted for transmit (NB: this can/will be handled
better when aggregation is pulled up to net80211)
turns out some devices do this and since we otherwise validate the station
is associated and don't use the aid for anything being lenient here allows
them to function

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral). Also there
no longer are separate wlan_scan* modules; this functionality is now
bundled into the wlan module.
