convert simple_{link,unlink,rmdir,rename,fill_super}() to new primitives

Browse Source 
Note that simple_unlink() et.al. are used by many filesystems; for now
they can not assume that persistency mark will have been set back
when the object got created.  Once all conversions are done we'll
have them complain if called for something that had not been marked
persistent.
