evolve: fix the broken behaviour on div resolution in relocation case
In content divergence resolution, I see that when "relocationreq" is
True which means both the cset are on different parent and relocation
is required. In this case when "divergent" is the one who is behind
the "other" cset in DAG, we swap them. At this point one thing we
missed is to update the evolvestate['divergent'].
Because of this in continue case we didn't get the right value
of obsmarkers creation.
In this patch I added the code to update the evolvestate when we swap
them.
Now as we know "divergent" and "other" can be swapped in some cases,
it is better to store the intial divergent separately in evolvestate
which is evolvestate['orig-divergent'] and later this value is used
to update the evolvestate['replacements'] which is the track of
revisions which has been resolved.
Changes in tests demonstrate the fixed behaviour.
Test for issue 5881 present at https://bz.mercurial-scm.org/show_bug.cgi?id=5881
===============================================================================
which is about that if the working copy parent is obsolete then evolve update
to its successor revision and stop; it doesn't continue to evolve remaining
revisions those were suppossed to evovle.

Prepare the directory by creating an orphan and update to its obsolete parent:
$ for ch in a b c; do echo $ch > $ch; hg ci -Am "added "$ch; done;
adding a
adding b
adding c
$ hg up 1 -q
$ hg ci --amend -m "updated b"
1 new orphan changesets
$ hg up 1
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
working directory parent is obsolete! (5f6d8a4bf34a)
(use 'hg evolve' to update to its successor: e6048a693c0d)

Test `hg evolve` evolve all the revisions specified by user:
$ hg evolve -r .::
update:[3] updated b
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
working directory is now at e6048a693c0d
move:[2] added c
atop:[3] updated b
