As a first step towards migrating to Bugzilla 5.0, we need to examine each Red Hat customization and decide whether it:

1. is no longer needed and can be discarded,
2. has been superseded by a change in the upstream 5.0,
3. should be pushed upstream, or
4. should remain as a Red Hat customization against 5.0.

This task is to generate a list of the items in the four categories above, so that we can then generate further sub-tasks of Bug 1095592 to handle those items.
