Revert the behavior change of 1409147, that made ra_local transform ra local
urls in unexpected ways to a more canonical form then svn_uri_canonicalize()
would.

* subversion/libsvn_ra_local/split_url.c
  (includes): Add path.h

  (svn_ra_local__split_URL): Split the passed url instead of construction one
    from the dirent. Add a huge comment explaining the operation.
