Add an ability to punt all unknown UDP traffic to the host
By default, VPP replies with ICMP error: port unreachable when receives
an ‘unknown’ UDP (destination port with no registered listener) packet.
An existing punt() API is extended to accept ALL (~0) as a L4 port
number and if used redirects all ‘unknown’ UDP packets to the host.
New ‘all’ option is added to the “set punt udp” CLI as well.
