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).

=================================================================
Test automatic unstability resolution for multiple advanced cases
=================================================================

There are dedicated test case for each instability, but this file check some
basic case for each type.

XXX dispatching each these test case in appropriate file would make sense.

  $ cat >> $HGRCPATH <<EOF

  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

  >   hg log -G --template \
  >     '{rev}:{node|short}@{branch}({phase}) bk:[{bookmarks}] {desc|firstline}\n' "$@"
