rewind: always compute successorsmap

We have had access to rewind targets (predecessors) in this function before,
but having access to current successors (in the form of successorsmap) is also
useful and will be used in following patches.

We're emptying successorsmap when --as-divergence is given to keep the current
behavior. It's done before using it for --dry-run and actual work.

This test file test the #6028 issue

evolve fails with mercurial.error.ProgrammingError: unsupported changeid '' of type <type 'str'>

Test
====

  $ hg init $TESTTMP/issue-6028
  $ cd $TESTTMP/issue-6028

create initial commit

  $ echo "0" > 0
  $ hg ci -Am 0
  adding 0

start new topics "a" and "b" both from 0

  $ hg up default
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg topics a
  marked working directory as topic: a
  $ echo "a" > a
  $ hg ci -Am a
  adding a
  active topic 'a' grew its first changeset
  (see 'hg help topics' for more information)

  $ hg up default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg topics b
  marked working directory as topic: b
  $ echo "b" > b
  $ hg ci -Am b
  adding b
  active topic 'b' grew its first changeset
  (see 'hg help topics' for more information)

create branch "integration" from 0, merge topics "a" and "b" into it

  $ hg up default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg branch integration
  marked working directory as branch integration

  $ hg merge a
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m "merged a"

  $ hg merge b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m "merged b"

commit a bad file on topic "a", merge it into "integration"

  $ hg up a
  switching to topic a
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo "a bad commit" >> a_bad_commit
  $ hg add a_bad_commit
  $ hg ci -m "a bad commit"
  $ hg up integration
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg merge a
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m "merged a bad commit"

add more commits on both topics and merge them into "integration"

  $ hg up a
  switching to topic a
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo "aa" >> a
  $ hg ci -m "aa"
  $ hg up integration
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg merge a
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m "merged aa"

  $ hg up b
  switching to topic b
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo "bb" >> b
  $ hg ci -m "bb"
  $ hg up integration
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg merge b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m "merged bb"

create instability by pruning two changesets, one in a topic, one a merge

  $ hg log -r 5:6 -T '{rev}: {desc}\n'
  5: a bad commit
  6: merged a bad commit

  $ hg prune -r 5:6
  2 changesets pruned
  3 new orphan changesets

  $ hg up 4
  2 files updated, 0 files merged, 1 files removed, 0 files unresolved

start the evolve

  $ hg evolve --update --no-all
  move:[8] merged aa
  atop:[4] merged b
  working directory is now at c920dd828523

casually checking issue6141: position of p2 is not changed

  $ hg log -r 'predecessors(.) + .'

test that we successfully got rid of the bad file

  $ hg d --git -r 'predecessors(.)' -r '.'
  diff --git a/a_bad_commit b/a_bad_commit
  deleted file mode 100644
  --- a/a_bad_commit

evolve creates an obsolete changeset above as 11

  $ hg evolve -l
  61eff7f7bb6c: aa
    orphan: 487c225d33af (obsolete parent)
  
  2b5a7b3298d9: merged bb

    orphan: 61eff7f7bb6c (orphan parent)
  
  $ hg evolve -r .
  skipping c920dd828523, consider including orphan ancestors

test that the suggestion works

  $ hg evolve -r 'parents(".")::'
  move:[7] aa
  atop:[1] a
  switching to topic a
  move:[11] merged aa
  move:[10] merged bb
  working directory is now at bdbfa73836d6
