/* Hardlinks : During image generation accompany the tree of IsoFileSrc
by a sorted structure of Ecma119Node.
by a sorted array of Ecma119Node.
The sorting order shall bring together candidates for being
hardlink siblings resp. having identical content.
This has to be in sync with the IsoFileSrc unification by
IsoRBTree and iso_file_src_cmp() which cannot be obsoleted
because Joliet and ISO1999 depend on it.
This is in sync with the IsoFileSrc unification by IsoRBTree

That tree cannot be obsoleted because Joliet and ISO1999 depend
on it. On the other hand, the Ecma119Node array includes objects
which have no IsoFileSrc attached. So both, tree and array, are
needed.
