[PATCH, take 2] libertas: implement SSID scanning for SIOCSIWSCAN

Do you mean that 

00:1D:60:14:33:2B   <empty SSID>
00:1D:60:14:33:2B   WLAN

should be unified into

00:1D:60:14:33:2B   WLAN

???


First I wanted to do that, but then I thought that maybe this is 
erraneous. An AP can have several SSIDs, one of them could be 
hidden, the other ones not hidden. E.g. this is easy to setup on 
a Cisco 123x or Cisco 124x access-point.



I also have a "take 3" of this patch now, because I adapted 
(after a chat with David on IRC) the outstanding patches from 
libertas-2.6 to wireless-testing. Two of the patches touched 
scan.c as well, so I rewrote my scan-for-specific-ssid patch to 
apply on top of the 5 David-Woodhouse-patches.
