rebase: prevent creating divergence

Before this patch rebase would create divergence when you were rebasing obsolete
changesets on a destination not containing one of its successors.
This patch introduces rebase.allowdivergence to explicitly allow
divergence creation with rebase.

  $ hg debugobsolete `hg log -r 11 -T '{node}\n'` --config experimental.evolution=all
  $ hg rebase -r . -d 10
  abort: all requested changesets have equivalents or were marked as obsolete
  (to force the rebase, set the config experimental.rebaseskipobsolete to False)
  [255]

27746:f0e9f38d250f

  $ hg debugobsolete `hg log -r 11 -T '{node}\n'` --config experimental.evolution=all
  $ hg rebase -r . -d 10
  abort: all requested changesets have equivalents or were marked as obsolete
  (to force the rebase, set the config experimental.rebaseskipobsolete to False)
  [255]

If a rebase is going to create divergence, it should abort
