src: allow to map key to nfqueue number
Allow to specify a numeric queue id as part of a map.
The parser side is easy, but the reverse direction (listing) is not.
'queue' is a statement, it doesn't have an expression.
Add a generic 'queue_type' datatype as a shim to the real basetype with
constant expressions, this is used only for udata build/parse, it stores
the "key" (the parser token, here "queue") as udata in kernel and can
then restore the original key.
Add a dumpfile to validate parser & output.
JSON support is missing because JSON allow typeof only since quite
recently.
Joint work with Pablo.
Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1455
