        handler. Add parent locations to rmmod and unlink handlers.
        * libcsupport/include/rtems/libio_.h: Add a path length to
        rtems_filesystem_evaluate_path. Add
        rtems_filesystem_evaluate_relative_path, rtems_filesystem_dirname,
        and rtems_filesystem_prefix_separators. Remove
        rtems_filesystem_evaluate_parent.

        * libcsupport/src/rmdir.c: Find the parent pathloc then the node
        pathloc from that node. Remove the call to find the parent given
        the node pathloc.

        call. Set the device into the rdev field.
        * libcsupport/src/unlink.c: Find the parent pathloc then the node
        pathloc from that node. Remove the call to find the parent given
        the node pathloc.
        * libfs/src/dosfs/fat.c, libfs/src/dosfs/msdos_format.c: Get the
        disk device number from the stat rdev field.
        * libfs/src/dosfs/msdos.h: Add the length parameter to the eval
        call. Add the parent pathloc to the rmnod handler.
        * libfs/src/dosfs/msdos_dir.c: Add the parent pathloc to the rmnod
        handler.
        * libfs/src/dosfs/msdos_eval.c: Add the length parameter to the
        eval and token call.
        * libfs/src/imfs/imfs_directory.c: Add the parent pathloc to the
        rmnod handler.
        * libfs/src/imfs/imfs_fchmod.c: Do not test the mode flags for
        only the allowed flags. Add the missing flags spec'ed in the POSIX
        standard.
        * libfs/src/imfs/imfs_fsunmount.c, libfs/src/imfs/imfs_rmnod.c,
        libfs/src/imfs/imfs_unlink.c, libfs/src/imfs/memfile.c: Add the
        parent node. Currently ignored in the IMFS.
        * libfs/src/imfs/imfs_stat.c: Return the device number in the rdev
        field.
        * libfs/src/imfs/imfs_mknod.c, libfs/src/imfs/imfs_symlink.c : Add
