Add DECLARE STATEMENT support to ECPG.
DECLARE STATEMENT is a statement that lets users declare an identifier
pointing at a connection. This identifier will be used in other embedded
dynamic SQL statement such as PREPARE, EXECUTE, DECLARE CURSOR and so on.
When connecting to a non-default connection, the AT clause can be used in
a DECLARE STATEMENT once and is no longer needed in every dynamic SQL
statement. This makes ECPG applications easier and more efficient. Moreover,
writing code without designating connection explicitly improves portability.
