b032f27c36 Multi-bss (aka vap) support for 802.11 devices.
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.

98fed7a4ab Fix adhoc mode to scan all available channels for a bss to join
while still restricting auto-channel select to only those channels
permitted by regulatory constraints (sorta, we're still missing the
checks to honor radar and noadhoc status on channels).  This somehow
got lost in the initial merge of the revised scanning code.

1a4ae5c45b Be more careful handling off-channel frames: if the driver (wrongly)
sends frames up the stack after changing the current channel then
the lookup by ieee channel number may fail leaving a null ptr in
se_chan; if this happens fallback to the channel recorded when the
frame is processed (curchan).  Since the frame doesn't contribute
to scan results for the sta this is acceptable.

5773d80e69 Correct handling of off-channel frames:
o do not override the home channel recorded for the sta when the frame is
  received off-channel; this fixes a problem where we might think the sta
  was operating on the channel the frame was received on causing association
  requests to be ignored/rejected (likely cause of kern/99036)
o don't include rssi of off-channel frames in the avg rssi used to select
  a bss; this gives us a better estimate of the signal we will see for the
  station when on-channel

- provide dummy routines for ic_scan_curchan and ic_scan_mindwell, we do not support those operations.
- add ieee80211_scan_done() to tell the scanning module that all channels have been scanned.
- pass IEEE80211_S_SCAN state off to net80211 so it can initiate scanning
- fix overflow in the rates array
- scale the rate value passed back from the firmware scan to the units that net80211 uses.

b54b1bab4b Change the channel number in the scan results struct to be a pointer to the
operating channel and use this in the scan cache rather than directly using
ic_curchan. Some firmware cards can only do a full scan and so ic_curchan does
not have the correct value.

Also add IEEE80211_CHAN2IEEE to directly dereference ic_ieee from the channel
to be used in the fast path.
