Big wpi(4) overhaul! Not by me!

This is a sync against iwn(4) and openbsd.

- Add power management support;
- Add background scanning support;
- Fix few LORs;
- Handle rfkill switch state changes properly;
- Fix recovering after firmware failure;
- Add more error checking;
- Cleanup & disable by default debug output;
- Update macroses names;
- Other various fixes;
- Add IBSS support:
  - don't set data_ntries field for management frames;
- Add AHDEMO support:
    - fix padding;
- Sync eeprom functions;
- Use CMD_RXON_ASSOC where possible;
- Enable HW CCMP encryption/decryption for pairwise keys;
- Fix filter flags for CMD_RXON.

Tested (by submitter) - iwn 3945 NIC.  I have one somewhere; I'll
validate this later on and revert it if it's a problem.

Thanks!
