Jack Christensen adbb38f298 Do not allow protocol messages larger than ~1GB 
The PostgreSQL server will reject messages greater than ~1 GB anyway.
However, worse than that is that a message that is larger than 4 GB
could wrap the 32-bit integer message size and be interpreted by the
server as multiple messages. This could allow a malicious client to
inject arbitrary protocol messages.

Jack Christensen f512b9688b Add PgConn.SyncConn 
This provides a way to ensure it is safe to directly read or write to
the underlying net.Conn.

Jack Christensen 05440f9d3f Drastically increase allowed test times for potato CI 
The context timeouts for tests are designed to give a better error
message when something hangs rather than the test just timing out.
Unfortunately, the potato CI frequently has some test or another
randomly take a long time. While the increased times are somewhat less
than optimal on a real computer, hopefully this will solve the
flickering CI.

Dan McGee 0328d314ea Use bytes.Equal rather than bytes.Compare ==/!= 0 
As recommended by go-staticcheck, but also might be a bit more efficient
for the compiler to implement, since we don't care about which slice of
bytes is greater than the other one.

Jack Christensen b74c109f61 Optimize tracing 
The addition of tracing caused messages to escape to the heap. By
avoiding interfaces the messages no longer escape.

Jack Christensen 5714896b10 Restructure sending messages 
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.

Jack Christensen e641d0a5ad Reuse connection read buffer 
To avoid extra copies and small allocations previously large
read buffers were allocated and never reused. However, the down side of
this was greater total memory allocation and the possibility that a
reference to a single byte could pin an entire buffer.

Now the buffer is reused.
