P2P: Hidden SSID support

[Holger Schurig]

I don't know the answer, but hidden SSID is something you shouldn't
use anyway. Don't rely security-wise on hiding some SSID.

The 802.11 connection protocols have at several message formats
(beacon, assoc request, assoc response, authentication request,
authentication response, probe request, probe response) that transmit
the SSID in cleartext. The so-called hidden-SSID hides the SSID only
from the beacons. From nowhere else.

So, you simply cannot hide your SSID.

If you can't hide it anyway, when why try it?
