Subject: [PATCH 1/2] Autoincrement trove classifier id.

This should allow to not have to bother about getting the id right when
inserting new.

Legacy PyPI does a :

```python
cursor = st.get_cursor()
    cursor.execute("select max(id) from trove_classifiers")
    id = cursor.fetchone()[0]
    if id:
        id = int(id) + 1
    else:
        id = 1
```

Then insert, which IIUC is subject to race conditions.
