In certain cases, the 802.11 mesh pathtable code wants to
iterate over all of the entries in the forwarding table from
the receive path, which is inside an RCU read-side critical
section. Enable walks inside atomic sections by allowing
GFP_ATOMIC allocations for the walker state.
Change all existing callsites to pass in GFP_KERNEL.

Avoid users having to manually load the module by adding a module
alias allowing it to be autoloaded by the lwt infra.

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

Create ila directory in preparation for supporting other hooks in the
kernel than LWT for doing ILA. This includes:
- Moving ila.c to ila/ila_lwt.c
- Splitting out some common functions into ila_common.c
