Ian Norden 708425c4d6 rebase; extract factories and the mocks they are dependent on to
libraries/shared; adjust omni test_helpers to drop and recreate
checked_headers table to avoid reaching 1600 column limit after repeated
tests (dropping columns doesn't actually remove them from contributing
to that limit)
