 * Purpose: parse database monitor item params string "user=<user> password=     *

 *          <password> DSN=<dsn> sql=<sql>" into parameter values.               *

 *                                                                               *

 * Parameters:  params     - [IN] the params string                              *

 *              dsn        - [OUT] the ODBC DSN output buffer                    *

 *              user       - [OUT] the user name output buffer                   *

 *              password   - [OUT] the password output buffer                    *

 *              sql        - [OUT] the sql query output buffer                   *

 *                                                                               *

 * Comments: This function allocated memory to store parsed parameters, which    *

 *           must be freed later by the caller.                                  *

 *           Failed (or absent) parameters will contain empty string "".         *

 *                                                                               *
