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).

KeyError: b'topic' on history-rewriting commands (issue6500)

  $ . $TESTDIR/testlib/common.sh

Making sure we're not caching .topic() results for memctx or anything else that's not stored on-disk

  $ hg init issue6500-caching-memctx
  $ cd issue6500-caching-memctx

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > evolve =
  > topic =
  > EOF

for this test we need 2 changesets with amend_source, one with topic and one without

  $ hg topics foo
  marked working directory as topic: foo
  $ echo apple > a
  $ hg ci -qAm 'apple'
  $ echo apricot > a
  $ hg ci --amend -m 'apricot'

not using `hg topics --clear -r .` here because that would remove amend_source, see _changetopics()

  $ hg topics --clear
  $ hg ci --amend -m 'no foo apricot'

  $ hg log --hidden -r 1+2 -T '{rev}: {join(extras, " ")}\n'
  1: amend_source=* branch=default topic=foo (glob)
  2: amend_source=* branch=default (glob)

creating and handling 2 memctx instances (based on 1 and then 2) should work

  $ hg touch --hidden -r 1+2 --duplicate
  switching to topic foo

make sure extras stay the same

  $ hg log --hidden -r 3+4 -T '{rev}: {join(extras, " ")}\n'
  3: __touch-noise__=* amend_source=* branch=default topic=foo (glob)
  4: __touch-noise__=* amend_source=* branch=default (glob)
