rebase: lose the comparison to `nullmerge`

For a proper behavior of the `--rev` revision we will need another possible
state for revision ignored by rebase. We alter the comparison to `nullmerge`
to match this future lower state too.

  $ hg mv b b-renamed
  $ hg ci -m 'rename B'

Rename is tracked:

  $ hg tlog -p --git -r tip
  3: 'rename A' 
  diff --git a/a b/a-renamed
  rename from a
  rename to a-renamed
  
Rebase the revision containing the rename:

  $ hg rebase -s 3 -d 2
  saved backup bundle to $TESTTMP/a/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  3: 'rename A'

  o  2: 'rename B'

  o  1: 'B'

  o  0: 'A'
  

Rename is not lost:

  $ hg tlog -p --git -r tip
  3: 'rename A' 
  diff --git a/a b/a-renamed
  rename from a
  rename to a-renamed
  

Rebased revision does not contain information about b (issue3739)

Test rebase across repeating renames:

  $ hg init repo

  $ cd repo

  $ echo testing > file1.txt
  $ hg add file1.txt
  $ hg ci -m "Adding file1"

  $ hg rename file1.txt file2.txt
  $ hg ci -m "Rename file1 to file2"

  $ echo Unrelated change > unrelated.txt
  $ hg add unrelated.txt
  $ hg ci -m "Unrelated change"

  $ hg rename file2.txt file1.txt
  $ hg ci -m "Rename file2 back to file1"

  $ hg update -r -2
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ echo Another unrelated change >> unrelated.txt
  $ hg ci -m "Another unrelated change"
  created new head

  $ hg tglog
