we bailed if we couldn't collect the 16-bytes of data required
for an aes block cipher in 2 mbufs; now we deal with it. While
here make space accounting signed so a sanity check does the
right thing for malformed mbuf chains.

blindly assign unicast keys to key slot 0. Devices that need
alternate allocation logic must override this method.

don't mark the MORE_DATA bit when taking it off the ps queue, there's
no 802.11 header then; we must wait to do this at encap time so
mark the mbuf instead.

received and use this to decide whether or not to bump the refcnt.
This insures we only ever bump the refcnt once.

This fixes duplicative BSS entries(memory leaks as well) listed in
"ifconfig dev list scan" when a station fails to associate with an AP.

struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.
Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address
from driver private storage rather than sometimes being ac_enaddr.

it; instead pass the space occupied by the header down into the
crypto modules (except in the demic case which needs it only when
doing int in s/w)
o while here fix defrag to strip the header from 2nd and later frames
o teach decap code how to handle 4-address frames
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.
o don't pre-assign key index to the global key table entries so device
has a chance to decide what to use
o make ieee80211_crypto_newkey take the desired flags as an argument
instead of wacking the key structure directly; this eliminates a
bunch of code warts
o add a new flag IEEE80211_KEY_GROUP to indicate a key is a WPA Group
key so devices don't need to guess (temporarily add this flag in the
ioctl code until we can get wpa_supplicant+hostapd updated)
o shuffle IEEE80211_KEY_* bits to move flags used internally to the high
nibble of the flags word
