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).

Check we can find the topic extensions

  $ cat >> $HGRCPATH <<EOF
  > [ui]
  > logtemplate = {rev} - \{{get(namespaces, "topics")}} {node|short} {desc} ({phase})\n
  > [extensions]
  > rebase = 
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
  $ echo "topic=$(echo $(dirname $TESTDIR))/hgext3rd/topic/" >> $HGRCPATH

  $ mkcommit() {
  >    echo "$1" > "$1"
  >    hg add "$1"
  >    hg ci -m "add $1"
  > }

Create a simple setup

  $ hg topic foo
  marked working directory as topic: foo

  $ mkcommit ddd
  $ mkcommit eee
  $ mkcommit fff
  $ hg topic bar
  $ mkcommit ggg
  active topic '//bar' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit hhh
  $ mkcommit iii
