Fortran: Fix MPI_SIZEOF. What a disaster. :-(
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).

Many updates and bug fixes for the Fortran bindings. Sorry these
aren't separated out into individual commits; they represent a few
months of work in the Mercurial branch, and it seemed error-prone to
try to break them up into multiple SVN commits.
* Remove 2nd overloaded interfaces for MPI_TESTALL, MPI_TESTSOME,
MPI_WAITALL, and MPI_WAITSOME in the "mpi" module implementations
(because we're not allowed to have them, anyway -- it causes
complications in the profiling interface). This forced an MPI-2.2
errata in the MPI Forum; we applied the errata here (the array of
statuses parameter could not have a specific dimension specified in
the dummy argument). Fixes trac:3166.
* Similarly, fix type for MPI_ARGVS_NULL in Fortran
* Add MPI_3.0 function MPI_F_SYNC_REG (Fortran interfaces only).
* Add MPI-3.0 MPI_MESSAGE_NO_PROC in the mpi_f08 module.
* Added mpi_f08 handle comparison operators, per MPI-3.0 addendum to
the F08 proposal at the last Forum meeting.
* Added missing type(MPI_File) and type(Message) in mpi_f08 module.
* Fix --disable-mpi-io configure switch with all Fortran interfaces
* Re-factor the Fortran header files to be fundamentally simpler and
easier to maintain. Fortran constant values in the header files
are now generated by a script named mpif-values.pl during
autogen.pl (they were previously generated by mpif-common.pl, but
it was quite a bit more subtle/complex). A second commit will
follow this one to update svn:ignore values (just to ensure we
don't muck up the first commit with the SVN client getting confused
by the changed ignore values and new/changed files).
* Fix some dependencies for compile ordering in
ompi/mpi/fortran/use-mpi-ignore-tkr/Makefile.am.
* Fix bad wording in several places (.m4 file name, ompi_info output,
etc.): we previoulsy said "F08 assumed shape" when we really meant
"F08 assumed rank" (for Fortran gurus, those are very different
things).
* Removed the GREEK/SVN version string from mpif.h. It really had no
purpose being there.
Still to be done:
* Handling of 2D array of strings in MPI_COMM_SPAWN_MULTIPLE still
isn't right yet. Not sure how many people really care about this
:-), but it is still broken.
