fix a case of discarded arrays

XDMF can mark any number of arrays as scalars, ids etc.
VTK can only mark one and the way I was doing it was just wrong.
So choose the first (arbitrarily). Another valid choice is none.

bring back subsets

libxdmf::XdmfSet API is different now, comes over as one three
component wide array instead of three arrays
libxdmf::XdmfSet doesn't yet bring over set attributes so they
are not well tested. Next xdmf bump should bring them in.

Change-Id: Id1bd2434cfdb592b950b1e77c0763deae9931cc3
put array reuse in

xdmf arrays are shallow copied into VTK and deleted en masse at
the reader level instead of being deep copied and deleted for
every VTK user of them. With xincluded arrays especially, this is
a huge savings in terms of time and memory.
We use an LRU cache to delete only those arrays which were
not used in the previous frame and keep the rest around
because they are likely to be reused.

Add support for reading polyhedra.

This does not include support for side sets of polyhedra
as the underlying Exodus library function the reader uses
does not include support for polyhedra (plus, it would be
a significant effort).
