This data structure holds an array of allocated strings for use in nftnl_chain and nftnl_flowtable structs. For convenience, implement functions to clear, populate and iterate over contents. While at it, extend chain and flowtable tests to cover these attributes, too. Signed-off-by: Phil Sutter <phil@nwl.cc> Reviewed-by: Pablo Neira Ayuso <pablo@netfilter.org>
