undo-files: also remove the undo.backupfiles

The undo.backupfiles is dealt is directly managed by the transaction instead of
going through the `localrepo.undofiles`. We start doing minimal management for
it before using `cleanup_undo_files` on more situation. Proper handling of it
is an intermediate goal of this series.

Test rebase with obsolete
==========================

Enable obsolete

  $ cat >> $HGRCPATH << EOF
  > [command-templates]
  > log= {rev}:{node|short} {desc|firstline}{if(obsolete,' ({obsfate})')}
  > [experimental]
  > evolution.createmarkers=True
  > evolution.allowunstable=True
  > [phases]
  > publish=False
  > [extensions]
  > rebase=
  > drawdag=$TESTDIR/drawdag.py
  > strip=
  > EOF

Test that bookmark is moved and working dir is updated when all changesets have
equivalents in destination
  $ hg init rbsrepo && cd rbsrepo
  $ echo "[experimental]" > .hg/hgrc
  $ echo "evolution=true" >> .hg/hgrc
  $ echo root > root && hg ci -Am root
  adding root
  $ echo a > a && hg ci -Am a
  adding a
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo b > b && hg ci -Am b
  adding b
  created new head
  $ hg rebase -r 2 -d 1
  rebasing 2:1e9a3c00cbe9 tip "b"
  $ hg log -r .  # working dir is at rev 3 (successor of 2)
  3:be1832deae9a b (no-eol)
  $ hg book -r 2 mybook --hidden  # rev 2 has a bookmark on it now
  bookmarking hidden changeset 1e9a3c00cbe9
  (hidden revision '1e9a3c00cbe9' was rewritten as: be1832deae9a)
  $ hg up 2 && hg log -r .  # working dir is at rev 2 again
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  2:1e9a3c00cbe9 b (rewritten using rebase as 3:be1832deae9a) (no-eol)
  $ hg rebase -r 2 -d 3 --config experimental.evolution.track-operation=1
  note: not rebasing 2:1e9a3c00cbe9 mybook "b", already in destination as 3:be1832deae9a tip "b"
Check that working directory and bookmark was updated to rev 3 although rev 2
was skipped
  $ hg log -r .

  $ hg bookmarks

parent gets moved:

  $ hg update D1 -q
  $ hg bookmark book -i
  $ hg rebase -r B+D1 -d E
  rebasing 1:112478962961 B "B"
  note: not rebasing 5:15ecf15e0114 book D1 tip "D1", already in destination as 2:0807738e0be9 D2 "D2"
