[Mpi3-ft] MPI_Comm_reenable_any_source Alternatives

[Josh Hursey]

We have a 30 character limit, and need a better name for
MPI_Comm_reenable_any_source. 'reenable' was seen as misleading since
some messages are left in the matching queue, and not really
'disabled.' This function is really just a protective handshake with
the user so that the MPI library knows that the user has acknowledged
the loss of processes.

So if we keep the base MPI_Comm__any_source then we have 20
characters. Below are a list of replacement options that I came up
with from the old-dusty-thesaurus. Let me know which ones you like
best.

 20: MPI_Comm__any_source (base)
+ 5: allow
+ 7: approve
+ 5: bless
+ 7: certify
+ 5: grant
+ 6: permit
+ 6: ratify
+10: reactivate
+ 8: reenable
+ 8: sanction
+ 8: validate

I kind of like the 'validate' since we are already introducing that
concept as a means of confirming with the user a defined behavior.
