hwloc v1.5 does not support HWLOC_OBJ_OSDEV_COPROC nor hwloc_topology_dup(), so for this version : - do not search for coprocessors - do not try hwloc_topology_dup(), note this is not used anywhere in the code base Thanks Jeff for helping with the wording Signed-off-by: Gilles Gouaillardet <[email protected]> (back-ported from commit open-mpi/ompi@7e01be6)

This commit addresses two issues in osc/rdma:
1) It is erroneous to attach regions that overlap. This was being
allowed but the standard does not allow overlapping attachments.
2) Overlapping registration regions (4k alignment of attachments)
appear to be allowed. Add attachment bases to the bookeeping
structure so we can keep better track of what can be detached.
It is possible that the standard did not intend to allow #2. If that
is the case then #2 should fail in the same way as #1. There should
be no technical reason to disallow #2 at this time.
