Add a regression test for sending and writing zero bytes to sockets of
various types, as well as pipes and fifos for good measure. RELENG_6 currently passes all of these tests, but 7-CURRENT fails 0-byte writes and sends on all stream socket types (and fifos, as they are based on stream sockets). Bumped into by: peter Diagnosed by: jhb Problem of: andre
