- Tweaked the settings for mysql-connector-python; in Py2K, the
"supports unicode statements" flag is now False, so that SQLAlchemy
will encode the *SQL string* (note: *not* the parameters)
to bytes before sending to the database.  This seems to allow
all unicode-related tests to pass for mysql-connector, including those
that use non-ascii table/column names, as well as some tests for the
TEXT type using unicode under cursor.executemany().
- other mysql-connector fixes; latest version seems to do better on
function call counts
