HS 2.0: Terms and Conditions attributes in Access-Request messages

Browse Source 
This extends hostapd with two new configuration parameters
(hs20_t_c_filename and hs20_t_c_timestamp) that can be used to specify
that the Terms and Conditions attributes are to be added into all
Access-Request messages for Hotspot 2.0 STAs.
