rebase: backed out changeset cf8ad0e6c0e4 (issue5610)

Having a single transaction for rebase means the whole transaction gets rolled back
on error. To work around this a small hack has been added to detect merge
conflict and commit the work done so far before exiting. This hack works because
there is nothing transaction related going on during the merge phase.

However, if a hook blocks the rebase to create a changeset, it is too late to commit the
work done in the transaction before the problematic changeset was created. This
leads to the whole rebase so far being rolled back. Losing merge resolution and
other work in the process. (note: rebase state will be fully lost too).

Since issue5610 is a pretty serious regression and the next stable release is a
couple day away, we are taking the backout route until we can figure out
something better to do.

====================================
Testing head checking code: Case A-8
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category A: simple case involving a branch being superceeded by another.
TestCase 8: single-changeset branch indirect rewrite

  $ setuprepos
  creating basic server and client repo
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd client
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit A1
  created new head
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit A2
  created new head
  $ hg debugobsolete `getid "desc(A0)" ` `getid "desc(A1)"`
