Introduce a new displayname field for persons in the PostgreSQL storage
Extend the APIs for Revisions and Releases to honor the field by default,
unless the new ignore_displayname
argument is set.
Test Plan
- tested the 182.sql migration script manually
- all tests run without changes (except for one revision_log kwarg)
- still need to add new tests to exercise the new field
