    Define types for C calls in netlink_lib

    Previously this was not done, which meant all arguments were
    assumed to be ints. As long as we didn't get any large pointer
    addresses this worked fine, but for some reason the addition of
    threading to oslo.privsep triggered larger addresses that were then
    truncated. This caused segfaults in the underlying C library because
    we were passing it invalid pointers.

    This change sets argument and return types for all of the calls
    that are used in the module.
