I've queued these patches which convert nfnetlink to use the generic
netlink functions. Will push upstream after a bit more testing. Comments,
review and patches on top to use the typeful attribute parsing/dumping
functions (NLA_PUT_BE32, nla_get_u32, ...) welcome :)

[NETFILTER]: nfnetlink: convert to generic netlink attribute functions
Get rid of the duplicated rtnetlink macros and use the generic netlink
attribute functions. The old duplicated stuff is moved to a new header
file that exists just for userspace.
