[issue22272] sqlite3 memory leaks in cursor.execute

New submission from A. Libotean:
There are significant memory leaks when multiple insert statements are executed with distinct values.
sqlite3 version is 2.6.0
The attached file contains two variants:
* one which uses string interpolation to build the query: this generates severe leakeage
* the other one is using parametrized queries and the leakeage is not as bad
I'm assuming that somehow the query string reference is not freed properly.
