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.

At long last, the fabled revision to the affinity system has arrived. A more detailed explanation of how this all works will be presented here:

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.

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.

ras_base_node.c

This confusion has been around for awhile, caused by a long-ago decision to track slots allocated to a specific job as opposed to allocated to the overall mpirun instance. We eliminated that quite a while ago, but never consolidated the "slots_alloc" and "slots" fields in orte_node_t. As a result, confusion has grown in the code base as to which field to look at and/or update.

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