libnfnetlink: add version 1.0.0

    libnfnetlink is the low-level library for netfilter related kernel/userspace
    communication. It provides a generic messaging infrastructure for in-kernel
    netfilter subsystems (such as nfnetlink_log, nfnetlink_queue, nfnetlink_conntrack)
    and their respective users and/or management tools in userspace.
