evolve: move test for evolve --rev ordering in a separate file

evolve --rev reordering is a complicated enough topic to justify a separate
test.

Initial setup
  $ hg init testrevorder

  $ mkcommits p _a _b _c
  $ hg phase --public 0
  $ hg up 'desc(_a)'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo "aaa" > _a
  $ hg amend
  2 new unstable changesets

evolve --rev reorders the rev to solve instability, trivial case 2 revs wrong order
  $ hg evolve --rev 'desc(_c) + desc(_b)'

  atop:[5] add _a
  move:[3] add _c

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
  $ hg prune "desc(c1_)" -s "desc(c1prime)"
  1 changesets pruned
  3 new unstable changesets
  $ hg prune "desc(c2_)" -s "desc(c2prime)"
  1 changesets pruned
  $ hg prune "desc(c1prime)" -s "desc(c1second)"
  1 changesets pruned
  1 new unstable changesets
  $ hg log -G -r "desc(_d)::"
  @  22:a329855d0bc1@default(draft) add c1second

Second set of stack with no successor for b2_:
  $ mkstack "desc(_d)" b1_ b2_ b3_ b4_ >/dev/null
  $ mkstack "desc(_d)" b1prime b3prime >/dev/null
  $ hg prune "desc(b1_)" -s "desc(b1prime)"

  3 new unstable changesets
  $ hg prune "desc(b3_)" -s "desc(b3prime)"
  1 changesets pruned
  $ hg prune "desc(b2_)"
  1 changesets pruned

  $ hg log -G -r "desc(_d)::"
