obsolete: add a flag that allows fixing "bumped" changeset The first obsolescence flag is introduced to allows for fixing the "bumped" changeset situation. bumpedfix == 1. Creator of new changesets intended to fix "bumped" situation should not forget to add this flag to the marker. Otherwise the newly created changeset will be bumped too. See inlined documentation for details.
