Where is tdb?

[cclauss]

Several files try to import tdb but I can not find where tdb is defined.

infogami/core/dbupgrade.py:from infogami import tdb
infogami/plugins/links/db.py:from infogami import tdb
infogami/plugins/pages/code.py:from infogami import tdb

I did a grep for tdb, and it's not defined anywhere in infogami.

1. dbupgrade is documented as an action in infogami, but isn't imported or used anywhere in the project.
2. infogami/plugins/links/db.py and infogami/plugins/pages/code.py aren't used anywhere in infogami
3. None of the above seem to be used in openlibrary either.

The only plugins that openlibrary seems to use are infogami/plugins/api and infogami/plugins/wikitemplates.
