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).

Tests for the --stop flag for `hg evolve` command while resolving orphans
=========================================================================

The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on

This is testing cases when `hg evolve` command is doing orphan resolution.

Setup
=====

  > evolution.in-memory = yes
  > EOF

Testing `--stop` when no evolve is interrupted
==============================================

  $ hg evolve --stop
  abort: no interrupted evolve to stop
  [20]

Testing with wrong combinations of flags
========================================

  $ hg evolve --stop --rev 1
  abort: cannot specify both "--rev" and "--stop"
  [255]

  $ hg evolve --stop --continue
  abort: cannot specify both "--stop" and "--continue"
  [255]

  $ hg evolve --stop --all
