debian: update debhelper compat

Level before 9 are deprecated says debhelper 12. Upgrade to 10, which is
available in Debian oldstable and old Ubuntu releases to be conservative
(and since we probably don't need more).

evolve --rev reorders the rev to solve instability. Harder case, obsolescence
accross three stacks in growing rev numbers.

Evolve --rev more complex case: two sets of stacks one with prune an no successor, the other one
partially solvable
 
First set of stack:
  $ mkstack "desc(_d)" c1_ c2_ c3_ c4_ >/dev/null
  $ mkstack "desc(_d)" c1prime c2prime >/dev/null
  $ mkstack "desc(_d)" c1second >/dev/null

  1 changesets pruned

  $ hg prune "desc(c2_)" -s "desc(c2prime)"
  1 changesets pruned
  $ hg prune "desc(c1prime)" -s "desc(c1second)"
  1 changesets pruned
  1 new orphan changesets
