Improve the Oracle translate_error implementation

The improved implementation scans all the records associated with an error
handle. Furthermore, if it is established that the connection to the database
has been lost, the connection is marked as such. Additionally, all special
exceptions (deadlock, timeout, and connection_lost) are now supported.
