strip: strip obsmarkers exclusive to the stripped changeset
This is it, `hg strip --rev X` will now also remove obsolescence markers
exclusive to X. Since a previous changeset, the obsmarkers has been backed up
in the strip backup bundle, so it is possible to restore them.
Note: stripping obsmarkers means the precursors of the stripped changeset might no
longer be obsolete after the strip.
Stripping changeset without obsmarkers can be useful when building test case. So
It is possible to disable the stripping of obsmarkers using the
'devel.strip-obsmarkers' config option.
Test change have been carefully validated.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
