Ralph Castain 4ca495c7e3 In managed allocations, we need to ensure that all nodes are flagged as having their slots "given" in case the user incorrectly asks us to change them. Also need to update the HNP node's "slots_given" flag as we don't replace the orte_node_t object when inserting the node info for that node. ...

base.h

If (and only if) a user requests, set the default number of slots on any node to the number of objects of the specified type. This *only* takes effect in an unmanaged environment - i.e., if an external resource manager assigns us a number of slots, then that is what we use. However, if we are using a hostfile, then the user may or may not have given us a value for the number of slots on each node.

Makefile.am

Establish an MCA param "orte_allocation_required" so that a system can require the user have an RM-provided allocation in order to run. This helps prevent the problem where a user forgets to get an allocation on an RM-managed cluster, and then executes mpirun on the head node - thus causing all of their mpi procs to launch on the head node, usually bringing it to its knees.

ras_base_allocate.c

Add an option to treat dash-host specifications as "requested, but not required". So-called "soft" location requests can allow an application to execute even if the ideal allocation isn't available.

ras_base_close.c

Complete implementation of the --without-rte-support configure option. Working with Brian, this has been tested on RedStorm.

Sorry for mid-day commit, but I had promised on the call to do this upon my return.
