evolve: add some initial values in evolvestate This patch adds two values in evolvestate: evolvestate['relocate-div'] = False evolvestate['relocate-other'] = False which will be used by resolution of content-divergence as a flag to know if we need to relocate the divergent changesets. In upcoming patches we will remove the logic of swapping divergent/other (we do this swapping when divergent need to relocate) as this doesn't seems something solid we can rely on.
