merge: check filename case collision between changesets for branch merging

this patch makes branch merging abort when merged changesets have same
file in different case on case insensitive filesystem.

this patch does not prevent linear update which merges between target
and working contexts, because 'branchmerge' is False in such case.

  $ hg init
  $ touch unknown

  $ touch a
  $ hg add a
  $ hg ci -m "1"

  $ touch b
  $ hg add b
  $ hg ci -m "2"

Should show unknown

  $ hg status
  ? unknown
  $ hg revert -r 0 --all
  removing b

Should show unknown and b removed

  $ hg status
  R b
  ? unknown

Should show a and unknown

  $ ls
  a
  unknown
