HEADS UP: new wpa_supplicant and hostapd

[Sam Leffler]

I've imported v0.6.8 which is now the tip of the stable branch in 
Jouni's repository.  One side effect is there is now a combined tree in 
contrib.  You should see no regressions but this has been lightly tested 
so beware (and -Dwired support in wpa_supplicant is not tested).

Not sure what new functionality comes with this code.  If something is 
not enabled in the build that should be please let me know.
