dirstate: fix some problems for recursive case normalization (issue3342)

file in nested directory causes unexpected abort.

problems below should be fixed for recursive normalization route in
dirstate._normalize():

    1. rsplit() may cause unpacking into more than 2 elements.
       it should be called with 'maxsplit' argument to unpack
       into 'd, f'

    2. 'd' is replaced by normalized value prefixed with
       'self._root', but this makes 'folded' as absolute path,
       and it is unexpected one for caller of recursive
       normalization

  $ 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
