Adding WPS support for hostapd / wpa_supplicant

[Ted Merrill]

A further thought.

The question will arise whether the software architecture of putting
the WPS details into a server such as wsccmd is a good idea, or 
whether it should all be part of one program (i.e. the hostapd program).
Due to the time-consuming nature of the WPS crypto algorithms (depending of 
course upon the cpu power of the host) i think it is best that these are done 
in a separate thread from hostapd... using an entirely different process is a 
perfectly reasonable thing to do.
It will of course also simplify entirely replacing wsccmd with something less 
bloated, since the replacement can just be dropped in place.
