evolve: add logic to decide local and other side before merge

Before we perform merge between the two content-divergent csets,
this logic decides which cset would reside at which side i.e.
local or other.
for e.g.  in case of public content divergence where one side of
divergence is public, we always keep public one to local side.
(this logic of always keeping public one to local side may change in
future, but for now that's what it is.)

Make sure touch doesn't fail to warn about divergence (issue6107)

  $ hg init touchdiv
  $ cd touchdiv
  $ echo c > c
  $ hg add c
  $ hg ci -m "added c"

  $ hg amend -m "modified c"
  $ hg prune . -q

  $ hg touch -r "desc('added c')" --hidden
  $ hg touch -r "desc('modified c')" --hidden
  [1] modified c
