Python CUBRIDdb driver should implement cubrid_set_autocommit/cubrid_get_autocommit

First of all, I used the documentation from here:
http://packages.python.org/CUBRID-Python/

and I tried to use the CUBRIDdb driver.

Currently, rollback/commit functions from the driver cannot be used at all. That's why this bug is critical. It leads to various bugs because cubrid auto_commit mode cannot be enabled or disabled.

The following functions: cubrid_set_autocommit/cubrid_get_autocommit from the CCI driver should be called in the python driver also.

The "_cubrid" driver holds most of these functions, but it lacks others. "CUBRIDdb" should support these functions also.

Here is a test code:

import CUBRIDdb

con = CUBRIDdb.connect('CUBRID:localhost:33000:demodb', 'dba', '')
c = con.cursor()

c.execute("DROP TABLE IF EXISTS posts")
c.execute("CREATE TABLE posts(id integer,title varchar(255),body string,last_updated timestamp);")
args = (4, 'ddd', 'CUBRID-Python is Open Source!!')
c.execute('insert into posts(id, title, body, last_updated) values (?, ?, ?, SYSTIMESTAMP)', args)
con.rollback()

c.execute('select * from posts')
rows = c.fetchall()

for r in rows:
	print r

Here is a similar task in PHP (where everything works fine):

$conn = cubrid_connect("localhost", 33000, "demodb", "dba", "");
cubrid_set_autocommit($conn,CUBRID_AUTOCOMMIT_FALSE);

cubrid_query("DROP TABLE IF EXISTS tst");
cubrid_query("CREATE TABLE tst (a INTEGER)");
cubrid_query("INSERT INTO tst VALUES(1)");
cubrid_commit($conn);
cubrid_query("INSERT INTO tst VALUES(2)");
cubrid_query("INSERT INTO tst VALUES(3)");
cubrid_rollback($conn);

cubrid_disconnect($conn);

In the _cubrid driver there are other very useful functions such as: insert_id(), client_version(), server_version(), set_isolation_level().

I cannot use _cubrid driver as it is missing "executemany()" and "fetchall()".

Another useful function would be to get/set the charset used (I am referring to functions that exist in the CCI).
