src: allow to use typeof of raw expressions in set declaration
Use the dynamic datatype to allocate an instance of TYPE_INTEGER and set length and byteorder. Add missing information to the set userdata area for raw payload expressions which allows to rebuild the set typeof from the listing path. A few examples: - With anonymous sets: nft add rule x y ip saddr . @ih,32,32 { 1.1.1.1 . 0x14, 2.2.2.2 . 0x1e } - With named sets: table x { set y { typeof ip saddr . @ih,32,32 elements = { 1.1.1.1 . 0x14 } } } Incremental updates are also supported, eg. nft add element x y { 3.3.3.3 . 0x28 } expr_evaluate_concat() is used to evaluate both set key definitions and set key values, using two different function might help to simplify this code in the future.
