obslog: also display patch for rebased changesets

This applies the same logic that is used for "merge-diff" to rebased
changesets. The successors' content is compared to the content of the
predecessors rebased in-memory on the new parents.

This highlights the changes that were actually introduced while rebasing (like
conflict resolution or API adjustment).

As a side effect, obslog now also outputs slightly more diffs for splits,
showing what parts of the original big changeset were moved to the smaller
split components (but for now it only works for the first few changesets).

hg evolve --continue and obsmarkers after conflict resolution with no changes to commit (issue5967)

  $ . $TESTDIR/testlib/common.sh

  $ hg init issue5967

  $ echo apple > a
  $ hg ci -qAm 'apple'
  $ echo banana > a
  $ hg ci -m 'banana'

Amending revision 0 in a way that causes conflicts

  $ hg prev
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [0] apple
  $ echo apricot > a
  $ hg amend -m 'apricot'
  1 new orphan changesets

  $ hg glog
  @  2: apricot
  
  *  1: banana
  |
  x  0: apple
  

Trying to evolve, then manually discarding changes from revision 1

  $ hg evolve
  move:[1] banana
  atop:[2] apricot
  merging a
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  unresolved merge conflicts
  (see 'hg help evolve.interrupted')
  [240]

  $ echo apricot > a
  $ hg resolve --mark a
  (no more unresolved files)
  continue: hg evolve --continue

This will correctly notice that revision 1 can be dropped

  $ hg evolve --continue
  evolving 1:dd9b5dd30cd6 "banana"
  evolution of 1:dd9b5dd30cd6 created no changes to commit
  $ hg glog
  @  2: apricot
  

This is important: 1 should not have a successor (especially not revision 2)
