This PR cleans out all the functionality removed from MPI-3.0 in 2012. This includes a number of C and fortran functions and the entirety of the C++ bindings. The PR is a WIP intended to start the discussion about cleaning up code that is no longer supported by the standard. The intent is to bring this into master targeting the Open MPI 4.0 release.

To finish the cleanup a number of internal components needed to be modified. These components used the removed functions. The cleanup is mostly straightforward but the romio changes need to be looked at since it is likely I updated some of them incorrectly. @roblatham00, @bosilca, @jsquyres Please take a look.

@edgargabriel I will probably break out the ompio update into another PR. Seems like something that should go in regardless of the removal of MPI_Address.

@hjelmn sounds good to me.

Kinda funny. This PR deletes ~ 1% of all the LOC in the project. -12000 lines.

Failure was yet another place that needs to be touched when modifying fortran datatypes! Fixed.

This commit attempts to update the romio io component to not use
functions removed in MPI-3.0 (2012). This is a first cut and will
probably need to be reviewed for correctness.

This commit removes the functions that were removed from MPI-3.0 back
in 2012.

The C++ bindings were removed from the MPI standard in MPI-3.0 back in
2012. This commit removes them but leaves the glue necessary to build
mpicxx. Additional cleanup is probably needed.

Per discussion in May 2018 and https://github.com/open-mpi/ompi/wiki/5.0.x-FeatureList, we decided that the removal of all of these features would occur in the v5.0.x timeframe (i.e., deprecate / not build by default in the v4.0.x timeframe).

@awlauria awlauria added this to the v5.0.0 milestone Mar 19, 2020

It looks like this PR removed the cxx bindings (done in another pr), plus a bunch of other stuff. Per the 5.0 feature list - it looks like that "other stuff" was deferred to 6.0 and beyond. Is there anything here still wanted for 5.0?

This is definitely 6.0/beyond.
