While this test always worked on my machine, it flickered in CI. And to
be fair the test can't guarantee the condition it is testing. Work
around this by trying many times before admitting failure.
This eliminates an edge case that can cause a deadlock and is a
prerequisite to cheaply testing connection liveness and to recoving a
connection after a timeout.

initial not quite working non-blocking conn
Previously if we provided a parameter that was an array of strings such
as []string{"0.0.0.0/8"}, we would encode this when sending to Postgres
as ::ffff:0.0.0.0/8. From what I can tell, this is because when parsing
the IP/network using net functions, we get a byte array that is 16 bytes
long, even if it is an IPv4 network. In Inet.EncodeBinary(), we look at
the length of the IP to determine what family the input is, and saw it
as IPv6 because of this.
We now always normalize IPv4 addresses using To4().
Use an internal buffer in pgproto3.Frontend and pgproto3.Backend instead
of directly writing to the underlying net.Conn. This will allow tracing
messages as well as simplify pipeline mode.
