Fixes #4065: Move r30169 to v1.7 branch (remove choice buffer interfaces from fortran mpi module)

GK: Had to resolve "local edit, but file remove upon merge" types of
errors with r30170.  But the whole point of this CMR is to remove
these files, so it was ok.

r30169 [[BR]]
Per thread starting here:

    http://www.open-mpi.org/community/lists/users/2014/01/23327.php

Revert the Fortran mpi module default size to "small", meaning that we
won't provide interfaces for MPI subroutines that take a choice buffer
any more.  The short version is that MPI-3 p610:34-41 disallows it.

This commit simply removes all these subroutines from the build
process (i.e., remove them from nodist_libmpi_usempi_la_SOURCES).
Since MPI-3 actually forbids providing these interfaces, I'll do a
second commit to actually remove all the scripts and associated
Makefile.am junk.

r30170 [[BR]]
Part 2/companion to r30169: remove Fortran TKR interfaces for MPI
subroutines with choice buffers.

Addendum to #4079: Move r30198 to v1.7 branch (make statfs/statvfs more robust)

Problem was detected on OS X Mavericks after the original CMR was
completed, which led to r30206 on the trunk which fixes the problem.
RM gave me verbal approval to simply include this fix in the amended
CMR.
