With this commit, the multicast forwarding table, which has been previously filled up due to multicast tracker packets, will now be checked frequently (once per second) for timeouted entries. If so these entries get removed from the table.
Note, that a more frequent check interval is not necessary, as multicast data will not only be forwarded if an entry exists, but also if that one might not have timeouted yet.

I would probably break this up into four functions.
