optimize: expand implicit set element when merging into concatenation
Generalize the existing code to deal with implicit sets. When merging a
ruleset like the following:
udp dport 128 iifname "foo" #1
udp dport { 67, 123 } iifname "bar" #2
into a concatenation of statements, the following expansion need to
be done for rule #2:
67 . "bar"
123 . "bar"
The expansion logic consists of cloning the existing concatenation being
built and then append each element in the implicit set. A list of
ongoing concatenations being built is maintained, so further expansions
are also supported.
Extend test to cover for this use-case.
