[Mpi3-ft] Run-Through Stabilization

[Joshua Hursey]

I just updated the run-though stabilization proposal on the wiki with some more language for the collective operations and nonblocking variants of the collective validate functions.

I'm working on a few collective examples at the moment.

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.
