Commit 1017d323cafa ("src: support for selectors with different byteorder with
interval concatenations") was incomplete.
Switch byteorder of singleton values in a set that contains
concatenation of intervals. This singleton value is actually represented
as a range in the kernel.
After this patch, if the set represents a concatenation of intervals:
- EXPR_F_INTERVAL denotes the lhs of the interval.
- EXPR_F_INTERVAL_END denotes the rhs of the interval (this flag was
already used in this way before this patch).
If none of these flags are set on, then the set contains concatenations
of singleton values (no interval flag is set on), in such case, no
byteorder swap is required.
Update tests/shell and tests/py to cover the use-case breakage reported
by Eric.

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.

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.
