obsstore: add relevantmarkers method
We add a ``relevantmarkers`` method to fetch all markers that seem relevant to a
set of nodes. See function documentation about how this set is computed. This
will let us exchange only the markers that seem "relevant" to the set of
changesets related to a push or a pull.
The approach used to define "relevant" has been successfully tested in evolve
for 6 months.

Backing up ./a(*) (glob)
We have conflicts in the following files:
./a
$ sleep 1
$ echo e > a
$ echo f > f
$ mkdir dir
$ echo d > dir/d
$ echo d > dir/d2
$ darcs record -a -l -m p2
Finished recording patch 'p2'
test file and directory move
$ darcs mv f ff
Test remove + move
$ darcs remove dir/d2
$ rm dir/d2
$ darcs mv dir dir2
$ darcs record -a -l -m p3
Finished recording patch 'p3'
The converter does not currently handle patch conflicts very well.
When they occur, it reverts *all* changes and moves forward,
letting the conflict resolving patch fix collisions.
Unfortunately, non-conflicting changes, like the addition of the
"c" file in p1.1 patch are reverted too.
Just to say that manifest not listing "c" here is a bug.
