acl: add dumper for acls

A reasonable attempt will be made to shorten the output of terms, but
due to the nature of the ACL plugin in VPP, all ACLs will be unrolled
into their individual ACEs (called 'terms').

- src/dst-port will only be emitted with UDP/TCP
- icmp-typc/code will only be emitted with ICMP/ICMPv6
- icmp-code/type and source/destination-ports ranges will be collapsed
  where appropriate.
- if protocol is 0, only L3 information will be emitted

NOTE: a bug in the VPP plugin will allow for ICMP 'sport' and 'dport'
upper value to be 16 bits. If an ACE is retrieved from the dataplane
regarding an ICMP or ICMPv6 (referring the 16 bit values to icmp type
and code), they will be truncated and a warning issued.
