Add exception code to logAndThrowException

[smgallo]

Note: This is for 8.1

Description

Loggable:logAndThrowException() includes a message but does not include an error code. If an exception was provided in the options list, use the error code from that exception. Note that PDOException uses a string exception code (typically a five characters alphanumeric identifier defined in the ANSI SQL standard) while Exception uses an int. For these cases, use the driver specific error code instead so that we can propagate the error code with the newly thrown Exception.

For a mapping of MySQL specific error codes to ANSI-SQL identifiers see https://dev.mysql.com/doc/refman/5.5/en/error-messages-server.html
