[PATCH] support: add a utility function to canonicalise path separators

[NAKAMURA Takumi]

  I suggest "normalize_path" could do whole normalizations, eg. truncate /./

  And I think the internal separator should be '/' even if we are in win32.
  Just only "native" may use '\\'.

What is "escaped slash"?
