udp: add udp encap source port entropy support
Encode entropy value in UDP source port when requested per RFC 7510.
CLI already has "src-port-is-entropy", use zero UDP source port in API
to avoid breaking changes, since zero port is not something to be used
in wild.
Also, mark UDP encapsualtion API as mp-safe as already done for CLI.
Type: feature
