rebase: ensure rebase revision remains visible (issue4504)

Before this changeset rebase was getting very confused if any revision in the
rebase set became hidden. This was fairly easy to achieve if a rebased revision
was made visible by the working copy location. The rebase process would update
somewhere else and the revision would become hidden.

To work around this issue, we ensure rebased revisions remain visible for the
whole process.

This is a simple change suitable for stable. More subtle usage of unfiltered
repository in rebase may solve this issue more cleanly.

Just exercise debugindexdot
Create a short file history including a merge.
  $ hg init t
  $ cd t
  $ echo a > a
  $ hg ci -qAm t1 -d '0 0'
  $ echo a >> a
  $ hg ci -m t2 -d '1 0'
  $ hg up -qC 0
  $ echo b >> a
  $ hg ci -m t3 -d '2 0'
  created new head
  $ HGMERGE=true hg merge -q
  $ hg ci -m merge -d '3 0'

  $ hg debugindexdot .hg/store/data/a.i
  digraph G {
  	-1 -> 0
  	0 -> 1
  	0 -> 2
  	2 -> 3
  	1 -> 3
  }
