Jack Christensen a262126b5c Replace IsAlive with IsClosed 
IsAlive is ambiguous because the connection may be dead and we do not
know it. It implies the possibility of a ping. IsClosed is clearer -- it
does not promise the connection is alive only that it hasn't been
closed.

Jack Christensen 31705e586a Use pgconn.PreparedStatementDescription directly

Jack Christensen 6972a57421 pgtype.OID type should only be used for scanning and encoding values 
It was a mistake to use it in other contexts. This made interop
difficult between pacakges that depended on pgtype such as pgx and
packages that did not like pgconn and pgproto3. In particular this was
awkward for prepared statements.

This is preparation for removing pgx.PreparedStatement in favor of
pgconn.PreparedStatement.

Jack Christensen b7b52ff079 Require conn and pool configs to be created by ParseConfig 
This simplifies handling default values. Now there is no ambiguity
between a zero value and a default value. All default values are set by
ParseConfig and the user can modify them after the initial creation.

Jack Christensen 79f49ce300 Convert large objects to prepared statements 
This allows removing semi-obsolete fastpath interface support. See
https://www.postgresql.org/docs/current/libpq-fastpath.html. This also
simplifies introducing context support.

Jack Christensen 66625e6489 Prepare takes context 
Also remove PrepareEx. It's primary usage was for context. Supplying
parameter OIDs is unnecessary when you can type cast in the query SQL.
If it does become necessary or desirable to add options back it can be
added in a backwards compatible way by adding a varargs as last
argument.

Jack Christensen a6bdd8fd49 Hard code standard PostgreSQL types 
Instead of needing to instrospect the database on connection preload the
standard OID / type map. Types from extensions (like hstore) and custom
types can be registered by the application developer. Otherwise, they
will be treated as strings.

Jack Christensen c53c9e6eb5 Remove simple protocol and one round trip query options 
It is impossible to guarantee that the a query executed with the simple
protocol will behave the same as with the extended protocol. This is
because the normal pgx path relies on knowing the OID of query
parameters. Without this encoding a value can only be determined by the
value instead of the combination of value and PostgreSQL type. For
example, how should a []int32 be encoded? It might be encoded into a
PostgreSQL int4[] or json.

Removal also simplifies the core query path.

The primary reason for the simple protocol is for servers like PgBouncer
that may not be able to support normal prepared statements. After
further research it appears that issuing a "flush" instead "sync" after
preparing the unnamed statement would allow PgBouncer to work.

The one round trip mode can be better handled with prepared statements.

As a last resort, all original server functionality can still be accessed by
dropping down to PgConn.
