Remove support for IPIP tunnels in IPv4 multicast forwarding. XORP has

never used them; with mrouted, their functionality may be replaced by
explicitly configuring gif(4) instances and specifying them with the
'phyint' keyword.

Bump __FreeBSD_version to 700030, and update UPDATING.
A doc update is forthcoming.
