libpq can now talk to either 3.0 or 2.0 protocol servers. It first tries
protocol 3, then falls back to 2 if postmaster rejects the startup packet with an old-format error message. A side benefit of the rewrite is that SSL-encrypted connections can now be made without blocking. (I think, anyway, but do not have a good way to test.)
