evolve: handle a case in pubic-div when merging results in same as public
In public divergence resolution, what we do is:
1) first apply content divergence resolution
2) then phase divergent resolution on resultant node of 1) case
While doing case 1 it is possible that result of merging the two csets
would have same changes as public one contains. And then processing
the case 2 would create an empty commit which is not something we want
to do.
So this patch catch that same case when merging results in same as public
cset and don't create a new node, instead to solve the divergence
it just add a obsmarker from "other divergent" to "public divergent"
i.e. [other, (public,)]
Next patch will add the continue case handling for this same case.
This patch also adds the tests for the different cases which are possible
for the above mentioned case.
There is test for continue case too which is broken in this patch
and will be fixed in next patch.
This test file test the various messages when accessing obsolete
revisions.
