histedit: backout ebb5bb9bc32e

The faulty changeset use obsolescence marker to roll the repository back on
--abort. This is a problematic approach because --abort should be as close as an
actually transaction rollback as possible stripping all created data from the
repository (cf `hg rebase --abort` stripping all created changesets). Instead
ebb5bb9bc32e made all content created during the aborted histedit still
available in the repository adding obsolescence marker to make them hidden. This
will cause trouble to evolution user as a re-run of the same histedit (with
success) will likely result in the very same node to be "recreated" while
obsolescence marker would be in place for them. And canceling an obsoletion is
still a fairly complicated process.

This also rollback using obsmarkers instead of strip to clean up temporary node
on successful histedit run because the two change were not split in separated
changeset. Rolling that part back does not have significant consequence a will
have to be resubmitted independently
