merge: abort on file/directory case folding collisions (issue4892)

File/directory case folding collisions cannot be represented on case folding
systems and have to fail.

To detect this and abort early, utilize that for file/directory collisions, a
sorted list of case folded manifest names will have the colliding directory
right after the file.

(This could perhaps be optimized, but this way of doing it also has
directory/directory case folding in mind ... which however not is handled yet.)

basic test for hg debugrebuildstate

  $ hg init repo
  $ cd repo

  $ touch foo bar
  $ hg ci -Am 'add foo bar'
  adding bar
  adding foo

  $ touch baz
  $ hg add baz
  $ hg rm bar

  $ hg debugrebuildstate

state dump after

  $ hg debugstate --nodates | sort
  n 644         -1 set                 bar
  n 644         -1 set                 foo

status

  $ hg st -A
  ! bar
  ? baz
  C foo

  $ cd ..
