Subject: [PATCH v33 1/5] Add missing connection statuses to docs

The list of connection statuses that PQstatus might return during an
asynchronous connection attempt was incorrect:

1. CONNECTION_SETENV is never returned anymore and is only part of the
   enum for backwards compatibility. So it's removed from the list.
2. CONNECTION_CHECK_STANDBY and CONNECTION_GSS_STARTUP were not listed.

This addresses those problems. CONNECTION_NEEDED and
CONNECTION_CHECK_TARGET are not listed in the docs on purpose, since
these states are internal states that can never be observed by a caller
of PQstatus.
