Jack Christensen 832b4f9771 Fix: prepared statement already exists 
When a conn is going to execute a query, the first thing it does is to
deallocate any invalidated prepared statements from the statement cache.
However, the statements were removed from the cache regardless of
whether the deallocation succeeded. This would cause subsequent calls of
the same SQL to fail with "prepared statement already exists" error.

This problem is easy to trigger by running a query with a context that
is already canceled.

This commit changes the deallocate invalidated cached statements logic
so that the statements are only removed from the cache if the
deallocation was successful on the server.

Jack Christensen e5015e2fac pgx.Conn.Deallocate uses PgConn.Deallocate 
This uses the PostgreSQL protocol to deallocate a prepared statement
instead of a SQL statement. This allows it to work even in an aborted
transaction.

Jack Christensen bbe2653bc5 Prepare chooses statement name based on sql if name == sql 
This makes it easier to explicitly manage prepared statements.

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 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.

Evan Jones 9de41fac75 ParseConfig: default_query_exec_mode: Return arg in error 
If the default_query_exec_mode is unknown, the returned error
previously was:

    invalid default_query_exec_mode: <nil>

This changes it to return the argument. Add a test that unknown modes
fail to parse and include this string.

Jack Christensen 80eb6e1859 Remove sleeps in test 
Sleeping for a microsecond on Windows actually takes 10ms. This caused
the test to never finish. Instead use channel to ensure the two
goroutines start working at the same time and remove the sleeps.

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.
