        src/sys/fs/cd9660: cd9660_bmap.c cd9660_lookup.c cd9660_node.c
            cd9660_node.h cd9660_vfsops.c cd9660_vnops.c

Log Message:
Remove the hints "isodir" and "relocated" from cd9660_vget_internal()
and always reread the directory entry by inumber.  For directories
the directory entry is always its "." entry.

Always read directories via the device vnode to prevent buffer cache
inconsistency.  Keep i_devvp as a hint for fstat(1) and friends and
always use im_devvp for reads.  No need to vref()/vrele() i_devvp.

The additional bread is either cached because cd9660_lookup() just
released the buffer or will be used in the near future when the
directory gets traversed during lookup.
