Andrew Thompson 88d3b17273 Update ipw to work with the new net80211 stack, plus other driver improvements. 
- Add proper scanning support rather than letting the firmware grab the first
   access point
 - Overhaul state changes
 - Use macros for locking and provide _locked() versions of some functions
 - Increase debugging output
 - Use a callout rather than the old watchdog interface
 - Improve style, function names and defines
 - Add WPA (TKIP) support

Based heavily on a patchset provided by Sam Leffler.
