[isf-wifidog] Wifidog, portal page and Apple auto-login

[acv]

Marcos' comments below are not completely accurate, the ping was not a test itself,
in fact the gateway never bothered reading the response... The idea was to cause
the client to generate activity. Then activity (measured in bytes received from
client since last polling) was used.

In src/firewall.c, fw_sync_with_authserver() implements the timeout logic, it includes
this tidbit:

        /* Ping the client, if he responds it'll keep activity on the link.
	* However, if the firewall blocks it, it will not help. The suggested
	* way to deal witht his is to keep the DHCP lease time extremely
	* short: Shorter than config->checkinterval * config->clienttimeout */

ping was to be a BACKUP way of generating activity but using DHCP as suggested here is
much more reliable.

Cheers,

Alexandre
