This adds GAS/ANQP implementation into hostapd. This commit brings in the basic GAS/ANQP functionality, but only the ANQP Capability List element is supported. For testing purposes, hostapd control interface SET command can be used to set the gas_frag_limit parameter dynamically. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
