libpq: Trace all messages received from the server
Not all messages that libpq received from the server would be sent
through our message tracing logic. This commit tries to fix that by
introducing a new function pqParseDone which make it harder to forget
about doing so.
The messages that we now newly send through our tracing logic are:
- CopyData (received by COPY TO STDOUT)
- Authentication requests
- NegotiateProtocolVersion
- Some ErrorResponse messages during connection startup
- ReadyForQuery when received after a FunctionCall message
