* libblock/src/bdbuf.c: Update comments.
* libblock/src/bdpart.c, libblock/src/ide_part_table.c: Get the
device from the rdev field of the stat buf.

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.

call.
* libcsupport/src/eval.c: Add rtems_filesystem_prefix_separators,
rtems_filesystem_dirname,
rtems_filesystem_evaluate_relative_path. Add the length parameter
to the eval call.
* 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.
* libcsupport/src/stat.c: Add the length parameter to the eval
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.

the length parameter to the token call.
* libfs/src/nfsclient/src/nfs.c: Add the length parameter to the
eval call and parent node to the rmnod and unlink command.
* libmisc/shell/internal.h: Remove the libc mounter decl to make
public.
