DB migrations can go unchecked

[Dan Smith]

Currently DB migrations can be added to the tree without the corresponding migration tests. This is bad and means that we have some that are untested in the tree already.

    Require tests for DB migrations

    This patch makes it mandatory to have at least a check routine for each migration.
    Some migrations are special (like the compressed one at the beginning, and the
    placeholder migrations), and can be skipped. Also, all baremetal migrations are
    excepted from this policy since that code is deprecated and needs to go away soon.
