Change the priority of comm_failure and job_termination events to ensure we process final messages prior to terminating. Check for termination conditions when processing proc termination events as we may order proc termination when the daemon gets an exit command, but we can't see the proc actually terminate until we get out of that message event.
Jeff: probably easiest to review this by testing. I tested it under both Slurm and rsh on v1.7.5 as well as trunk

NOTE: I transferred the oshmem-disabled-by-default from the 1.7 branch to the trunk to minimize future disruption if/when we change that option.

In the function sstore_stage_select() the local variables
were set up and defined. Unfortunately this function was
never called. This patch moves variable set up to the
sstore_stage_register() function and checks the return
values of the variable initialization.

When compiling --with-ft there are a few compiler warnings about
unused variables. This patch fixes those compiler warnings.

The problem arises when a hostfile is used, and the user provides host names without specifying the slots= paramater. In these cases, we assign slots=1, but automatically allow oversubscription since that number isn't confirmed. We then provide a separate parameter by which the user can direct that we assign the number of slots based on the sensed hardware - e.g., by telling us to set the #slots equal to the #cores on each node. However, this has been set to "off" by default.
In order to make this a little less complex for the user, set the default such that we automatically set #slots equal to #cores (or #hwt's if use_hwthreads_as_cpus has been set) only for those cases where the user provides names in a hostfile but does not provide slot information.
Also cleanup some a couple of issues in the mapping/binding system:
* ensure we only override the binding directive if we are oversubscribed *and* overload is not allowed
* ensure that the MPI procs don't attempt to bind themselves if they are launched by an orted as any binding directive (no matter what it was) would have been serviced by the orted on launch
* minor cleanup to the warning message when oversubscribed and binding was requested

1. Changed rng_buff_t --> opal_rng_buff_t
2. All global variables obey the prefix rule
3. Old code has been removed
4. Found a couple of unnecessary includes

r of slots remaing to be assigned being only one/node. Regardless, it didn't work for the case where nodes were defined in ascending order of slots.
Tetsuya's proposed patch didn't solve the problem for me, but it did correct the case where cpus/proc > 1. The final patch requires that we loop over the assignment
algo until all procs are assigned or all nodes are filled - any remaining procs are then handled in the cleanup loop.

Running orte-restart requires an initialized sstore.
This opens the sstore component for FT builds just like
the snapc component.

With enabled fault tolerance code different functions
are selected during compilation. Most of the ft
code is #ifdef'd out. This #ifdef's more code out
so that compiler warnings like
warning: unused variable 'item' [-Wunused-variable]
opal_list_item_t *item;
are removed.

VERY tentatively schedule this for 1.7.5 - only to be applied if we see no troubles AND the branch is ready in advance.
