Jack Christensen fd0c65478e Fix prepared statement already exists on batch prepare failure 
When a batch successfully prepared some statements, but then failed to
prepare others, the prepared statements that were successfully prepared
were not properly cleaned up. This could lead to a "prepared statement
already exists" error on subsequent attempts to prepare the same
statement.

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.

Jack Christensen 9f00b6f750 Use context timeouts in more tests 
Tests should timeout in a reasonable time if something is stuck. In
particular this is important when testing deadlock conditions such as
can occur with the copy protocol if both the client and the server are
blocked writing until the other side does a read.

Jack Christensen 6defa2a607 Fix error when using BatchResults.Exec 
...on a select that returns an error after some rows.

This was initially found in by a failure with CockroachDB because it
seems to send a RowDescription before an error even when no rows are
returned. PostgreSQL doesn't.

Jack Christensen e7aa76ccf9 SendBatch now uses pipeline mode to prepare and describe statements 
Previously, a batch with 10 unique parameterized statements executed
100 times would entail 11 network round trips. 1 for each prepare /
describe and 1 for executing them all. Now pipeline mode is used to
prepare / describe all statements in a single network round trip. So it
would only take 2 round trips.

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 c3e41872a8 Resplit Begin and BeginEx 
This is in preparation for a Begin / Tx interface that will similate
nested transactions with savepoints.

In addition, this passes the TxOptions struct by value and thereby
removes an allocation.

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.
