New wireless drivers committed

I've recently imported four new wireless drivers into the tree:

ipw(4)  - driver for Intel PRO/Wireless 2100 adapters (MiniPCI).
iwi(4)  - driver for Intel PRO/Wireless 2200BG/2225BG/2915ABG
          adapters (PCI or MiniPCI).
ral(4)  - driver for Ralink RT2500 wireless adapters (PCI or CardBus).
ural(4) - driver for Ralink RT2500USB wireless USB 2.0 adapters.

ipw(4) and iwi(4) both require firmwares to operate.
These firmwares can't be redistributed with the base system due to
license restrictions.  See firmware licensing terms here:
http://ipw2100.sourceforge.net/firmware.php?fid=4
Ports which include the firmware images as well as the firmware loader
are being worked on.

A rather complete list of adapters supported by ral(4) and ural(4) can
be found here:  http://ralink.rapla.net/

The drivers have some known limitations:

ipw(4)  - HostAP mode is not supported due to firmware limitations.
          WPA (802.11i) support is being worked on.
iwi(4)  - IBSS support is not yet implemented.
          Monitor and HostAP modes are not supported due to firmware
          limitations.  WPA (802.11i) support is being worked on.
ral(4)  - WEP, TKIP and CCMP hardware encryption is not yet supported
          (encryption is currently done by software).
ural(4) - Does not support automatic adaptation of the transmit speed.

Any feedback would be greatly appreciated.
