meta templates are only there for ease of use (input/parsing).
When listing, they should be ignored:
set s4 { typeof ip version elements = { 1, } }
chain c4 { ip version @s4 accept }
gets listed as 'ip l4proto ...' which is nonsensical.
after this patch we get:
in: ip version @s4
out: (@nh,0,8 & 0xf0) >> 4 == @s4
.. which is (marginally) better.
Next patch adds support for payload decoding.
