5b7943db78 ompi/group: do not allocate ompi_proc_t's on group union/difference
This commit modifies the ompi_group_t union/difference code to compare/copy the
raw group values. This will either be a ompi_proc_t or a sentinel value. This
commit also adds helper functions to convert between opal process names and
sentinel values.

0bf06de3f1 group|comm: add initial support for group sentinel values
This commit modifies ompi's process list group object to support a
sentinel value for non-existant ompi_proc_t objects. The sentinel was
chosen to be the negative of the opal_process_name_t of the associated
ompi_proc_t. This takes advantage of the fact that on most (all?)
systems the top bit of a user-space pointer is never set. If this
changes then a new sentinel will be needed.

In addition this commit modifies the way ompi_mpi_comm_world is
initialized to fill in the group with sentinel values if the number of
processes exceeds the new add_procs behavior cutoff.

253444c6d0 == Highlights ==
1. New mpifort wrapper compiler: you can utilize mpif.h, use mpi, and use mpi_f08 through this one wrapper compiler
 1. mpif77 and mpif90 still exist, but are sym links to mpifort and may be removed in a future release
 1. The mpi module has been re-implemented and is significantly "mo' bettah"
 1. The mpi_f08 module offers many, many improvements over mpif.h and the mpi module

This stuff is coming from a VERY long-lived mercurial branch (3 years!); it'll almost certainly take a few SVN commits and a bunch of testing before I get it correctly committed to the SVN trunk.

== More details ==

Craig Rasmussen and I have been working with the MPI-3 Fortran WG and Fortran J3 committees for a long, long time to make a prototype MPI-3 Fortran bindings implementation.  We think we're at a stable enough state to bring this stuff back to the trunk, with the goal of including it in OMPI v1.7.  

Special thanks go out to everyone who has been incredibly patient and helpful to us in this journey:

 * Rolf Rabenseifner/HLRS (mastermind/genius behind the entire MPI-3 Fortran effort)
 * The Fortran J3 committee
 * Tobias Burnus/gfortran
 * Tony !Goetz/Absoft
 * Terry !Donte/Oracle
 * ...and probably others whom I'm forgetting :-(

There's still opportunities for optimization in the mpi_f08 implementation, but by and large, it is as far along as it can be until Fortran compilers start implementing the new F08 dimension(..) syntax.

Note that gfortran is currently unsupported for the mpi_f08 module and the new mpi module.  gfortran users will a) fall back to the same mpi module implementation that is in OMPI v1.5.x, and b) not get the new mpi_f08 module.  The gfortran maintainers are actively working hard to add the necessary features to support both the new mpi_f08 module and the new mpi module implementations.  This will take some time.

As mentioned above, ompi/mpi/f77 and ompi/mpi/f90 no longer exist.  All the fortran bindings implementations have been collated under ompi/mpi/fortran; each implementation has its own subdirectory:

{{{
ompi/mpi/fortran/
  base/               - glue code
  mpif-h/             - what used to be ompi/mpi/f77
  use-mpi-tkr/        - what used to be ompi/mpi/f90
  use-mpi-ignore-tkr/ - new mpi module implementation
  use-mpi-f08/        - new mpi_f08 module implementation
}}}

There's also a prototype 6-function-MPI implementation under use-mpi-f08-desc that emulates the new F08 dimension(..) syntax that isn't fully available in Fortran compilers yet.  We did that to prove it to ourselves that it could be done once the compilers fully support it.  This directory/implementation will likely eventually replace the use-mpi-f08 version.

Other things that were done:

 * ompi_info grew a few new output fields to describe what level of Fortran support is included
 * Existing Fortran examples in examples/ were renamed; new mpi_f08 examples were added
 * The old Fortran MPI libraries were renamed:
   * libmpi_f77 -> libmpi_mpifh
   * libmpi_f90 -> libmpi_usempi
 * The configury for Fortran was consolidated and significantly slimmed down.  Note that the F77 env variable is now IGNORED for configure; you should only use FC. Example:
{{{
shell$ ./configure CC=icc CXX=icpc FC=ifort ...
}}}

All of this work was done in a Mercurial branch off the SVN trunk, and hosted at Bitbucket.  This branch has got to be one of OMPI's longest-running branches.  Its first commit was Tue Apr 07 23:01:46 2009 -0400 -- it's over 3 years old!  :-)  We think we've pulled in all relevant changes from the OMPI trunk (e.g., Fortran implementations of the new MPI-3 MPROBE stuff for mpif.h, use mpi, and use mpi_f08, and the recent Fujitsu Fortran patches).

I anticipate some instability when we bring this stuff into the trunk, simply because it touches a LOT of code in the MPI layer in the OMPI code base.  We'll try our best to make it as pain-free as possible, but please bear with us when it is committed.

c63c4d6892 Fix bugs where (OMPI_ERROR == *) checks cannot be converted to (OMPI_SUCCESS != *) since the return codes are overloaded to return an "index" on success.
The fix is to just check if the return value is positive or not, since all the SOS encoded errors are *always* negative.

The real fix (as Ralph points out) is to change these functions (opal_pointer_array_add and mca_base_param*) to return the index as a pointer.

afbe3e99c6 * Wrap all the direct error-code checks of the form (OMPI_ERR_* == ret) with
(OMPI_ERR_* = OPAL_SOS_GET_ERR_CODE(ret)), since the return value could be a
 SOS-encoded error. The OPAL_SOS_GET_ERR_CODE() takes in a SOS error and returns
 back the native error code.

* Since OPAL_SUCCESS is preserved by SOS, also change all calls of the form
  (OPAL_ERROR == ret) to (OPAL_SUCCESS != ret). We thus avoid having to
  decode 'ret' to get the native error code.

95596d1814 - Move alignment and size output generated by configure-tests
into the OPAL namespace, eliminating cases like opal/util/arch.c
   testing for ompi_fortran_logical_t.
   As this is processor- and compiler-related information
   (e.g. does the compiler/architecture support REAL*16)
   this should have been on the OPAL layer.
 - Unifies f77 code using MPI_Flogical instead of opal_fortran_logical_t

 - Tested locally (Linux/x86-64) with mpich and intel testsuite
   but would like to get this week-ends MTT output


 - PLEASE NOTE: configure-internal macro-names and
   ompi_cv_ variables have not been changed, so that
   external platform (not in contrib/) files still work.

566a050c23 Next step in the project split, mainly source code re-arranging
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)
