    hostapd: add IEEE 802.11v support
    
    Add Wireless Network Management (IEEE 802.11v)
    support to:
    - hostapd-full
    - wpa_supplicant-full
    
    It must be enabled at runtime via UCI with:
    - option ieee80211v '1'
    
    Add UCI support for:
    - time_advertisement
    - time_zone
    - wnm_sleep_mode
    - bss_transition
