This allows handling queries where it is unknown if there will be a
result set or not. If it is not a result set returning query the
command tag will still be available.
ParameterOIDs passed to ConnPool.PrepareEx are used to prepare the statement
on existing connections in the pool. If additional connections are later
created ParameterOIDs are omitted, potentially causing query failures.
Methods defined on T are also available on *T. This change makes Value
consistent with database/sql Value implementations. It also makes Value,
EncodeBinary, and EncodeText more convenient to use because you can
pass T or *T as an argument to a query.
The MarshalJSON change is even more significant because without it
json.Marshal would generate the "%v" format instead of the implemented
MarshalJSON.
Thought this technically changes the interface, because *T will be
automatically dereferenced as needed it shouldn't be a breaking change.

- Use strongly typed errors internally
- SafeToRetry(error) streamlines retry logic over ErrNoBytesSent
- Timeout(error) removes the need to choose between returning a context
and an i/o error
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.

PreparedStatementDescription was too long. It also no longer entirely
represents its purpose now that it is also intended for use with
described statements.
