[Mpi3-ft] Run-Through Stabilization

[Joshua Hursey]

I just updated the proposal with the following:
 - Collective examples (barrier, bcast, gather, scan, exscan)
 - Initial pass at wording for Ch. 6 Groups, Contexts, Communicators, and Caching
 - Moved the validate functions to Ch. 6, where they should reside
 - General cleanup, example fixes

I think the Ch.6 changes will need some discussion, and is what I hope to discuss next week for those at the forum. For those not at the forum next week, I'll leave some time on the teleconf to discuss this as well.

This is an attempt to pull apart the current FT proposals into two camps: stabilization, and recovery. The run-through stabilization proposal is meant to provide the foundation for and a complement to an eventual recovery proposal.

I modified some of the interfaces based on some recent experimentation with the interfaces. I have also been reading through various parts of the standard to find semantics, interfaces, and discussions that will need to be modified in order to support run-though stabilization.

This way I can introduce the proposal and we can start discussing some of the concepts. My hope is that this proposal helps spark some more discussion in the working group.
