Make use of 128b user cookies

Introduce optional 128-bit action cookie.
Like all other cookie schemes in the networking world (eg in protocols
like http or existing kernel fib protocol field, etc) the idea is to
save user state that when retrieved serves as a correlator. The kernel
_should not_ intepret it. The user can store whatever they wish in the
128 bits.

The support for this has not been accepted upstream in net-next yet.
Therefore submitting it into iproute2 is premature.
Pleas resubmit when the kernel part (and uapi) are upstream.
