XREQ and others race on TTL.

The TTL in these cases should have been atomic.  To facilitate
things we actually introduce an atomic int for convenience.  We
also introduce a convenience nni_msg_must_append_u32() and
nni_msg_header_must_append_u32(), so that we can eliminate some
failure tests that cannot ever happen.  Combined with a new test
for xreq, we have 100% coverage for xreq and more coverage for
the other REQ/REP protocols.
