    hostapd: add UCI option for Multiple BSSID
    
    Add an UCI option to enable Multiple BSSID Advertisement. Enabling this
    will announce all BSSIDS on a phy in a single beacon frame. The
    interface that is brought up first will be the transmitting profile, all
    others are non-transmitting profiles and will be advertised in the
    Multiple BSSID element in Beacon and Probe Response frames of the first
    interface.
    
    This depends on driver and client support. Enabling this will result in
    all but the first interface not being visible at all for clients that do
    not support it.
