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.)
