Put the clearing of possible embedded scope in an __KAME__ block.
...
This code does not really need to be optional since for non embedded
scope link local addresses this is a NOP.

Handle carp(4) as HTYPE_ETHER.

This fixes "dhcrelay -i carpX" that used to work when dhcrelay didn't care.

Add support for "DHCP-over-IPsec" by implementing RFC 3046 (DHCP Relay
...
Agent Information Option) and RFC 3456 (DHCP Configuration of IPsec
Tunnel Mode). This allows to configure various IPsec clients
dynamically via DHCP; dhcrelay needs to listen on enc0 and forward
requests to a DHCP server that supports RFC 3046, like I recently did
for dhcpd(8).
