Remove shifts-by-0. These can occur after binop postprocessing
has adjusted the RHS value to account for a mask operation.
Example: frag frag-off @s4
Is internally represented via:
[ exthdr load ipv6 2b @ 44 + 2 => reg 1 ]
[ bitwise reg 1 = ( reg 1 & 0x0000f8ff ) ^ 0x00000000 ]
[ bitwise reg 1 = ( reg 1 >> 0x00000003 ) ]
[ lookup reg 1 set s ]
First binop masks out unwanted parts of the 16-bit field.
Second binop needs to left-shift so that lookups in the set will work.
When decoding, the first binop is removed after the exthdr load
has been adjusted accordingly. Constant propagation adjusts the
shift-value to 0 on removal. This change then gets rid of the
shift-by-0 entirely.
After this change, 'frag frag-off @s4' input is shown as-is.

These tests work, but I omitted a few lines that do not:
in: frag frag-off @s4 accept
in: ip version @s8
out: (frag unknown & 0xfff8 [invalid type]) >> 3 == @s4
out: (ip l4proto & pfsync) >> 4 == @s8
Next patches resolve this.

This did not store the 'op' member and listing always treated this as ipv6
extension header.
Add test cases for this.

This should store the index of the protocol template, but
&x[i] - &x[0] is always i, so remove the divide. Also add test case.

The integer_type uses BYTEORDER_INVALID byteorder (which is implicitly
handled as BYTEORDER_BIG_ENDIAN).

Add sets using unspecific string/integer types, one with
osf name, other with vlan id. Neither type can be used directly,
as they lack the type size information.
