repoview: pin revisions for `local` and `other` when a merge is active

I've hit this a couple of times, where pulling with a dirty `wdir` obsoletes
`p1` and updating to the successor results in merge conflicts.  The problem was
resolving them failed immediately, complaining that the old checkout was
filtered.

The change in `test-rebase-obsolete.t` is because there's an outstanding merge
conflict in a rebase operation.  The summary prompt to merge seems incorrect for
this scenario, but that's an existing issue.

     This object is used to access a filtered version of a repository without
     altering the original repository object itself. We can not alter the
     original object for two main reasons:
     - It prevents the use of a repo with multiple filters at the same time. In
       particular when multiple threads are involved.
     - It makes scope of the filtering harder to control.
 
     This object behaves very closely to the original repository. All attribute
     operations are done on the original repository:
     - An access to `repoview.someattr` actually returns `repo.someattr`,
     - A write to `repoview.someattr` actually sets value of `repo.someattr`,
     - A deletion of `repoview.someattr` actually drops `someattr`
       from `repo.__dict__`.
 
     The only exception is the `changelog` property. It is overridden to return
     a (surface) copy of `repo.changelog` with some revisions filtered. The
     `filtername` attribute of the view control the revisions that need to be
     filtered.  (the fact the changelog is copied is an implementation detail).
 
     Unlike attributes, this object intercepts all method calls. This means that
     all methods are run on the `repoview` object with the filtered `changelog`
     property. For this purpose the simple `repoview` class must be mixed with
     the actual class of the repository. This ensures that the resulting
     `repoview` object have the very same methods than the repo object. This
     leads to the property below.
 
         repoview.method() --> repo.__class__.method(repoview)
 
     The inheritance has to be done dynamically because `repo` can be of any
     subclasses of `localrepo`. Eg: `bundlerepo` or `statichttprepo`.

 Divergence cases due to obsolete changesets

 We should ignore branches with unstable changesets when they are based on an
 obsolete changeset which successor is in rebase set.

 Changeset d and its descendants are excluded to avoid divergence of d, which
 would occur because the successor of d (d') is also in rebaseset. As a
 consequence f (descendant of d) is left behind.

 If the rebase set has an obsolete (d) with a successor (d') outside the rebase
 set and none in destination, we still get the divergence warning.
 By allowing divergence, we can perform the rebase.
