    hostapd: add owe_transition_ifname
    
    Add the owe_transition_ifname config option to wifi-ifaces.
    
    This allows to configure OWE transition VAPs without adding SSID / BSSID
    to the uci conifg but instead autodiscovering these parameters from
    other networks on the same PHY.
    
    The following configuration creates a OWE transition mode network
    constellation.
    
    config wifi-iface 'open0'
            option device 'radio0'
            option ifname 'open0'
            option network 'lan'
            option mode 'ap'
            option ssid 'FreeNet'
            option encryption 'none'
            option owe_transition_ifname 'owe0'
    
    config wifi-iface 'owe0'
            option device 'radio0'
            option ifname 'owe0'
            option network 'lan'
            option mode 'ap'
            option ssid 'owe_tm.FreeNet'
            option encryption 'owe'
            option hidden '1'
            option owe_transition_ifname 'open0'
