[Mpi3-ft] MPI_Comm_validate parameters

[Joshua Hursey]

I made some adjustments to the wiki page per the teleconf today. I also added the set diagrams that I mentioned:
  https://svn.mpi-forum.org/trac/mpi-forum-web/attachment/wiki/ft/run_through_stabilization/RT-validation-sets.pdf

I have not updated any of the interfaces outside of Ch. 6. I'll work on propagating those changes in the next few days, and let you all know when that is ready. But Ch. 2 and 6 are probably ready for a first glance.
