Rework UDP source and sink, with incompatible API changes

Remove source address specifications for sink; add connect() and
disconnect() to sink; add get_port() to source; add optional EOF
signaling (using zero-length packets) to sink and source; modify
dial_tone, vector, and audio examples to match new code; add qa
test case.
