Wez Furlong 007f571beb for the transactions test case, detect working transactions before attempting to run the tests.
Additional ugliness required because mysql does stupid stuff like this:

mysql> CREATE TABLE foo (id int) TYPE=innodb;
Query OK, 0 rows affected, 2 warnings (0.00 sec)
mysql> SHOW CREATE TABLE foo;
CREATE TABLE `foo` (
  `id` int(11) default NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1

In addition, BEGIN, COMMIT and ROLLBACK all succeed, even when no tables
support transactions.
