Allow RADIUS server address to be replaced

The new hostapd parameters auth_server_addr_replace and
acct_server_addr_replace can now be used to replace the configured IP
address instead of adding a new RADIUS server. This is mainly useful for
testing purposes where the address can be changed over control interface
during AP operation.
