MTT found that the addition of the MPI_SIZEOF interfaces to mpif.h was
causing a linker error with the Absoft compiler. Absoft is working on
a fix, but we can workaround the issue for now. See comment in
Makefile.am in this commit for a lengthy explanation.

of the topology is higher than the communicator size
It is possible to have a topology degree higher than the size of the communicator.
For example, a periodic cartesian communicator on MPI_COMM_SELF. This will leave
the neighborhood collectives with a request buffer that is too small. This commit
adds a call that will dynamically increase the size of the request buffer if it
is too small.
A better fix would be to create the topology *before* calling the coll_select
routine on a communicator. This will take some discussion and the solution will
not likely be ready anytime soon.
Thanks to Lisandro Dalcin for reporting this.

gfortran 4.8 does not support storage_size() on all relevant types
that we need. So add a configure test to check and see if the
compiler's storage_size() intrinsic supports enough types for us to do
MPI_SIZEOF.
Also remove an accidentally redundant check for fortran INTERFACE.

What started as a simple ticket ended up reaching the way up to the
MPI Forum.
It turns out that we are supposed to have MPI_SIZEOF for all Fortran
interfaces: mpif.h, the mpi module, and the mpi_f08 module.
It further turns out that to properly support MPI_SIZEOF, your Fortran
compiler *has* support the INTERFACE keyword and ISO_FORTRAN_ENV. We
can't use "ignore TKR" functionality, because the whole point of
MPI_SIZEOF is that the implementation knows what type was passed to it
("ignore TKR" functionality, by definition, throws that information
away). Hence, we have to have an MPI_SIZEOF interface+implementation
for all intrinsic types, kinds, and ranks.
This commit therefore adds a perl script that generates both the
interfaces and implementations for MPI_SIZEOF in each of mpif.h, the
mpi module, and mpi_f08 module (yay consolidation!).
The perl script uses the results of some new configure tests:
* check if the Fortran compiler supports the INTERFACE keyword
* check if the Fortran compiler supports ISO_FORTRAN_ENV
* find the max array rank (i.e., dimension) that the compiler supports
If the Fortran compiler supports both INTERFACE and ISO_FORTRAN_ENV,
then we'll build the MPI_SIZEOF interfaces. If not, we'll skip
MPI_SIZEOF in mpif.h and the mpi module. Note that we won't build the
mpi_f08 module -- to include the MPI_SIZEOF interfaces -- if the
Fortran compiler doesn't support INTERFACE, ISO_FORTRAN_ENV, and a
whole bunch of ther modern Fortran stuff.
Since MPI_SIZEOF interfaces are now generated by the perl script, this
commit also removes all the old MPI_SIZEOF implementations (which were
laden with a zillion #if blocks).

As noted in the comments of these files, they aren't used. Instead,
the Fortran interfaces for WTICK/WTIME just BIND(C) invoke the
back-end C functions (yay BIND(C)!). Hence, there's no need to keep
these old wrapper files around any more.

Replace our old, clunky timing setup with a much nicer one that is only available if configured with --enable-timing. Add a tool for profiling clock differences between the nodes so you can get more precise timing measurements. I'll ask Artem to update the Github wiki with full instructions on how to use this setup.
