decnet: Parse netlink attributes on our own
decnet is the only subsystem left that is relying on the global netlink attribute buffer rta_buf. It's horrible design and we want to get rid of it. This converts all of decnet to do implicit attribute parsing. It also gets rid of the error prone struct dn_kern_rta. Yes, the fib_magic() stuff is not pretty. It's compiled tested but I need someone with appropriate hardware to test the patch since I don't have access to it.
