MYSQL_TYPE_NEWDECIMAL

Added support for the type MYSQL_TYPE_NEWDECIMAL. It now works like
MYSQL_TYPE_DECIMAL. Unfortunately there cannot be a test case until
we have a working information_schema plugin as part of the source
distribution.

No error code was returned by mysqldump if it detects that binary
logging is not enabled on the server.
Fixed by returning error code.

                    sporadically

Under some circumstances, the mysql_insert_id() value after SELECT ...
INSERT could return a wrong value. This could happen when the last
SELECT ... INSERT did not involve an AUTO_INCREMENT column, but the
value of mysql_insert_id() was changed by some previous statements.

Fixed by checking the value of thd->insert_id_used in
select_insert::send_eof() and returning 0 for mysql_insert_id() if it
is not set.
