Modify the OMPI paffinity and mapping system to support socket-level mapping and binding. Mostly refactors existing code, with modifications to the odls_default module to support the new capabilities.
...
Adds several new mpirun options:
* -bysocket - assign ranks on a node by socket. Effectively load balances the procs assigned to a node across the available sockets. Note that ranks can still be bound to a specific core within the socket, or to the entire socket - the mapping is independent of the binding.
* -bind-to-socket - bind each rank to all the cores on the socket to which they are assigned.
* -bind-to-core - currently the default behavior (maintained from prior default)
* -npersocket N - launch N procs for every socket on a node. Note that this implies we know how many sockets are on a node. Mpirun will determine its local values. These can be overridden by provided values, either via MCA param or in a hostfile
Similar features/options are provided at the board level for multi-board nodes.

Deleted one too many lines...might be good to set the value of oldnode!

Restore the original API to terminate individual processes instead of the entire job. This was originally removed as we didn't at that time know how to take advantage of it. Some of us are now working on proactive resilience methods that move procs prior to node failure, so this is now a required API. Modify the odls, plm, and orted functions to support this new functionality.
...
Continue work on the resilient mapper, completing support for fault groups.

Enable restart of individual processes upon command via the errmgr callback function. It needs an external application to drive this capability, so normal operations shouldn't be affected.
...
Does not support MPI applications. More work coming to update daemon accounting on movement of procs across nodes.

Ensure we accurately count the number of new daemons to be launched, especially if we are restarting processes.
...
Have the resilient mapper also setup for new daemons in case the PLM needs them.

Add a resilient mapping capability - currently maps by fault groups (if provided), still need to add the remapping capability for failed procs.
