This patch implements an ILA tanslation table. This table can be
configured with identifier to locator mappings, and can be be queried
to resolve a mapping. Queries can be parameterized based on interface,
direction (incoming or outoing), and matching locator. The table is
implemented using rhashtable and is configured via netlink (through
"ip ila .." in iproute).
The table may be used as alternative means to do do ILA tanslations
other than the lw tunnels

Adding new module name ila. This implements ILA translation. Light
weight tunnel redirection is used to perform the translation in
the data path. This is configured by the "ip -6 route" command
using the "encap ila <locator>" option, where <locator> is the
value to set in destination locator of the packet. e.g.
ip -6 route add 3333:0:0:1:5555:0:1:0/128 \
encap ila 2001:0:0:1 via 2401:db00:20:911a:face:0:25:0
Sets a route where 3333:0:0:1 will be overwritten by
2001:0:0:1 on output.
