Jeff Squyres b0b17c62aa Protect against orte_proc_applied_binding being NULL. It is now possible for orte_proc_applied_binding to be NULL (e.g., if you mpirun --bind-to none), so we need to ensure we don't pass it down to opal_hwloc_base_cset2*str(). Also, take the opprotunity to de-duplicate some strings that are used in multiple places. Refs trac:4073 This commit was SVN r30204.

This extension provides a single new function, OMPI_Affinity_str(),
that takes a format value and then provides 3 prettyprint strings as
output:

fmt_type: is an enum that tells OMPI_Affinity_str() whether to use a
resource description string or layout string format for ompi_bound and
currently_bound output strings.

ompi_bound: describes what sockets/cores Open MPI bound this process
to (or indicates that Open MPI did not bind this process).

currently_bound: describes what sockets/cores this process is
currently bound to (or indicates that it is unbound).

exists: describes what processors are available in the current host.

See OMPI_Affinity_str(3) for more details.
