[PATCH nf-next 0/2] netfilter: helper set support

[Florian Westphal <fw@strlen.de>]

This adds support to set the conntrack helper from nftables, using
nft set ct helper "foo" syntax.

Helpers are defined through the objref infrastructure.

Open question: should NFT_MSG_GETOBJ_RESET get rejected for this new type?

A future patch could extend the attributes so we can also handle module
specific settings, such as ftp loose mode, or configure the number of
allowed expectations.
