conntrack: add nfct_set_attr_l and ATTR_HELPER_INFO
This adds the ATTR_HELPER_INFO that can be used to send binary data
that will be attached to the conntrack. This is useful for the
user-space connection tracking support.
This patch also adds a new interface:
nfct_set_attr_l(attr, type, value, length);
that is used to set the variable length helper information.
