libalias: Add support for EIM NAT

Add support for endpoint-independent mapping ("full cone NAT") in
Libalias's UDP NAT.

This conforms to RFC 4787 requirements 1 and 3. All UDP packets sent out from a
particular internal address:port leave via the same NAT address:port,
regardless of their destination.

Add some libalias tests and supporting defines.

libalias tests: Mark an unused variable with __unused.

It is not trivial to remove this set but unused variable since it
assigned to inside of a macro body, so just mark it with __unused
instead.
