fd2093cef8 Add statement type convenience methods to CommandTag and optimize 
Added convenient way to check whether a statement was a select, insert,
update, or delete. These methods do not allocate.

RowsAffected now does not allocate even when a large number of rows are
affected. It also is multiple times faster, though the absolute change
is inconsequential.

- Use strongly typed errors internally
- SafeToRetry(error) streamlines retry logic over ErrNoBytesSent

6feea0c1c5 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.

da9fc85c44 Rename PreparedStatementDescription to StatementDescription 
PreparedStatementDescription was too long. It also no longer entirely
represents its purpose now that it is also intended for use with
described statements.
