[patch] export, rename fill_kobj_path and get_kobj_path_length

[Robert Love <rml@ximian.com>]

Greg,

Per our discussion, the following patch exports fill_kobj_path and
get_kobj_path_length and adds them to kobject.h.

I also renamed them to kobject_get_path_len and kobject_fill_path,
respectively, to match the name space.

I need these for a kobject-based kevent.  Others may find them
fascinating as well.

	Robert Love


Export some internal kobject helpers.
