mq: add an '-e/--exact' option to qpush

This patch adds an '--exact/-e' option to qpush that will try to push the
patches in the correct location in the DAG.  Specifying this option does the
following:

* If --move is specified, abort. It makes no sense to move a patch to the front
  of the queue and try to apply it to its parent, because its parent is one of
  the patches we just moved it in front of!
* If patches are already applied, abort. We don't want patch changesets
  scattered throughout the DAG.
* If local changes are present, abort unless --force is used, as usual.
* Find the first patch we're going to push (if we're pushing multiple patches
  with a target or --all).
* If that patch doesn't have a parent, abort, obviously.
* If the parent doesn't exist in the repo, abort.  Something is wrong.
* Update to the parent, then continue pushing the patches as normal.

Test issue 902

  $ hg commit -m "test2"
  $ hg branch test
  marked working directory as branch test
  $ hg rollback
  rolling back to revision -1 (undo commit)
  $ hg branch

Test rollback of hg before issue 902 was fixed

  $ hg commit -m "test3"
  $ hg branch test
  marked working directory as branch test
  $ rm .hg/undo.branch
  $ hg rollback
  rolling back to revision -1 (undo commit)
  Named branch could not be reset, current branch still is: test
  $ hg branch
  test

rollback by pretxncommit saves commit message (issue 1635)
