[PATCH v3 4/7] Add internal functions to search for alternate doc types

Publicly we are only exposing the non-ghost documents (of "type"
"mail").  But internally we might want to inspect the ghost messages
as well.

This changeset adds two new private interfaces to queries to recover
information about alternate document types.
