Gerald Combs f9661850d1 Add support for AirPcap, an upcoming wireless product from CACE. Support
is disabled by default, and can be enabled by setting AIRPCAP_CONFIG
in config.nmake.  The code is currently limited to Windows, but should
be adaptable to other platforms.

The official announcement won't come until next week, so you'll have to
read the source for details.  :)
