rebase: properly handle unrebased revision between rebased one

With rebase taking multiple roots it is possible to have revision in the "rebase
domain" not rebased themself. We do not want rebased revision above them to be
detached. We want such revision to be rebased on the nearest rebased ancestors.
This allows to preserve the topology of the rebase set as much a possible

To achieve this we introduce a new state `revignored` which informs
`defineparents` of the situation.

The test in `test-rebase-obsolete.t` was actually wrote and his now fixed.

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

Enable obsolete

  $ cat > ${TESTTMP}/obs.py << EOF
  > import mercurial.obsolete
  > mercurial.obsolete._enabled = True
  > EOF
  $ cat >> $HGRCPATH << EOF
  > [ui]
  > logtemplate= {rev}:{node|short} {desc|firstline}
  > [phases]
  > publish=False
  > [extensions]'
  > rebase=
  > 
  > obs=${TESTTMP}/obs.py
  > EOF

Setup rebase canonical repo

  $ hg init base
  $ cd base
  $ hg unbundle "$TESTDIR/bundles/rebase.hg"
  adding changesets
  adding manifests
  adding file changes
  added 8 changesets with 7 changes to 7 files (+2 heads)
  (run 'hg heads' to see heads, 'hg merge' to merge)
  $ hg up tip
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
