In ARP header, destination ether address sits between source IP and
destination IP addresses. Enum arp_hdr_fields had this wrong, which
in turn caused wrong ordering of entries in proto_arp->templates. When
expanding a combined payload expression, code assumes that template
entries are ordered by header offset, therefore the destination ether
address match was printed as raw if an earlier field was matched as
well:
| arp saddr ip 192.168.1.1 arp daddr ether 3e:d1:3f:d6:12:0b
was printed as:
| arp saddr ip 192.168.1.1 @nh,144,48 69068440080907
Note: Although strictly not necessary, reorder fields in
proto_arp->templates as well to match their actual ordering, just to
avoid confusion.

This special operator is required for cases where missing operator does
not lead to same results as equal operator, i.e. with bitmasks on RHS.

Instead of the generic "left" and "right", use "key" and "value".

For raw payloads, property "name" is not needed, it's clearly identified
by base/offset/len properties.
In non-raw payload expressions, rename property "name" to "protocol" as
suggested during NFWS.

Lessons learned from fwd statement: We must not assume a given
statement/expression may not receive further properties in the future.
Therefore make meta value an object with a property "key" instead of
just a string containing the key name.

This extends nft-test.py by optional JSON testing capabilities,
activated via '-j'/'--enable-json' parameter).
JSON testing happens for all rules which are supposed to work: After a
rule has been added and the existing tests (payload, ruleset listing
output) have been performed, basically the same test is done again using
a recorded JSON equivalent and (if necessary) a recorded listing output.
The code tries to ease new test case creation overhead by
auto-generating JSON equivalent input via listing the (non-JSON) rule in
JSON format. Also, differing netlink debug and listing output are stored
in *.got files to assist in analyzing/fixing failing test cases.
