netfilter: nf_tables: variable sized set element keys / data
This patch changes sets to support variable sized set element keys / data up to 64 bytes each by using variable sized set extensions. This allows to use concatenations with bigger data items suchs as IPv6 addresses. As a side effect, small keys/data now don't require the full 16 bytes of struct nft_data anymore but just the space they need.
