Log:
  MFC r240410:
  
    Avoid mapping ENOENT to ENOTDIR for non-existent path components.
  
    The ENOTDIR mapping was introduced in r235266 for kern/128933 based on
    an interpretation of the somewhat ambiguous language in the POSIX realpath
    specification.  The interpretation is inconsistent with Solaris and Linux,
    a regression from 9.0, and does not appear to be permitted by the
    description of ENOTDIR:
  
         20 ENOTDIR Not a directory.  A component of the specified pathname
                 existed, but it was not a directory, when a directory was
                 expected.
