9e524a41cf Re-implement ompi_info in C, replacing the prior C++ code. This removes the last C++ code from the OMPI code base, thus relieving the requirement for C++ support unless the user requests the C++ bindings.
Jeff will update the build system later to remove the C++ checks per the above caveat.

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.

51e2b5dcef - Make the maximum length user strings configurable... Namely
MPI_MAX_PROCESSOR_NAME
      MPI_MAX_ERROR_STRING
      MPI_MAX_OBJECT_NAME
      MPI_MAX_INFO_KEY
      MPI_MAX_INFO_VAL
      MPI_MAX_PORT_NAME
      MPI_MAX_DATAREP_STRING

   Defaults stay as theyr currently are -- and now give an explanation on the
   min/max values being used in a central place...
   m4-macro _OPAL_WITH_OPTION_MIN_MAX_VALUE may be benefical in other parts
   of the configure system.

 - We need some of these in the lower level OPAL for an upcoming commit!
   All other levels base their values on them.

3e847c19f0 Per RFC: MPI Interface Extensions Infrastructure
Add infrastructure for MPI Interface Extensions. This allows a developer to create new MPI interfaces that are non-standard.

The following email thread describes the functionality proposed in the RFC:

The following wiki page describes how to use and enable the extensions:

916eb1fb1e - As proposed in RFC and telcon, warn the user about deprecated
functionality (per MPI-2.1). This warning can be toggled using
   --enable-mpi-interface-warning (default OFF), but can be
   selectively turned on passing
       mpicc -DOMPI_WANT_MPI_INTERFACE_WARNING

   Using icc, gcc < 4.5, warnings (such as in mpi2basic_tests) show:
     type_vector.c:83: warning: ‘MPI_Type_hvector’ is deprecated
     (declared at /home/../usr/include/mpi.h:1379)

   Using gcc-4.5 (gcc-svn) these show up as:
     type_vector.c:83: warning: ‘MPI_Type_hvector’ is deprecated
     (declared at /home/../usr/include/mpi.h:1379):
     MPI_Type_hvector is superseded by MPI_Type_create_hvector in MPI-2.0


   Jeff and I propose to turn such warnings on with Open MPI-1.7 by default.


 - Detection of user-level compiler is handled using the preprocessor
   checks of GASnet's other/portable_platform.h (thanks to Paul Hargrove
   and Dan Bonachea) adapted into ompi/include/mpi_portable_platform.h
   (see comments).

   The OMPI-build time detection is output (Familyname and Version)
   with ompi_info.

   This functionality (actually any upcoming __attribute__) are turned
   off, if a different compiler (and version) is being detected.


 - Note, that any warnings regarding (user-compiler!=build-compiler)
   as discussed in the RFC are _not_ included for now.


 - Tested on Linux with --enable-mpi-interface-warning on
   Linux, gcc-4.5 (deprecated w/ specific msg)
   Linux, gcc-4.3 (deprecated w/o specific msg)
   Linux, pathscale 3.1 (deprecated w/o specific msg)
   Linux, icc-11.0 (deprecated w/o specific msg)

   Linux, PGI-8.0.6 accepts __deprecated__ but does not issue a warning,
   further investigation needed...

4be24521aa Modify the orte_process_info structure to handle a broader range of process types by replacing the individual booleans with a 32-bit bitmap. Use a set of #define's to define the individual bits, and a set of matching macros to test for them. Update the orte code base to use the macros instead of the booleans.
Minor mod to the ompi layer to use the new #define's - just one-line name replacements.

4d8a187450 Two major things in this commit:
* New "op" MPI layer framework
 * Addition of the MPI_REDUCE_LOCAL proposed function (for MPI-2.2)

= Op framework =

Add new "op" framework in the ompi layer.  This framework replaces the
hard-coded MPI_Op back-end functions for (MPI_Op, MPI_Datatype) tuples
for pre-defined MPI_Ops, allowing components and modules to provide
the back-end functions.  The intent is that components can be written
to take advantage of hardware acceleration (GPU, FPGA, specialized CPU
instructions, etc.).  Similar to other frameworks, components are
intended to be able to discover at run-time if they can be used, and
if so, elect themselves to be selected (or disqualify themselves from
selection if they cannot run).  If specialized hardware is not
available, there is a default set of functions that will automatically
be used.

This framework is ''not'' used for user-defined MPI_Ops.

The new op framework is similar to the existing coll framework, in
that the final set of function pointers that are used on any given
intrinsic MPI_Op can be a mixed bag of function pointers, potentially
coming from multiple different op modules.  This allows for hardware
that only supports some of the operations, not all of them (e.g., a
GPU that only supports single-precision operations).

All the hard-coded back-end MPI_Op functions for (MPI_Op,
MPI_Datatype) tuples still exist, but unlike coll, they're in the
framework base (vs. being in a separate "basic" component) and are
automatically used if no component is found at runtime that provides a
module with the necessary function pointers.

There is an "example" op component that will hopefully be useful to
those writing meaningful op components.  It is currently
.ompi_ignore'd so that it doesn't impinge on other developers (it's
somewhat chatty in terms of opal_output() so that you can tell when
its functions have been invoked).  See the README file in the example
op component directory.  Developers of new op components are
encouraged to look at the following wiki pages:

  https://svn.open-mpi.org/trac/ompi/wiki/devel/Autogen
  https://svn.open-mpi.org/trac/ompi/wiki/devel/CreateComponent
  https://svn.open-mpi.org/trac/ompi/wiki/devel/CreateFramework

= MPI_REDUCE_LOCAL =

Part of the MPI-2.2 proposal listed here:

    https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/24

is to add a new function named MPI_REDUCE_LOCAL.  It is very easy to
implement, so I added it (also because it makes testing the op
framework pretty easy -- you can do it in serial rather than via
parallel reductions).  There's even a man page!

49be4b1e45 Fixes trac:1383
Lenny and I went back and forth on whether we should simply register
another "mpi_paffinity_alone" MCA param and then try to figure out
which one was set in ompi_mpi_init, but there was difficulty in
figuring out what to do.  So it seemed like the Right Thing to do was
to implement what was committed in r18770; then we could tell where
MCA parameters were set from and you could do Better Things (this is
also useful in the openib BTL, where parameters can be set either via
MCA parameter or via an INI file).

But after that was done, it seemed only a few steps further to
actually implement two new features in the MCA params area:

 * Synonyms (where one MCA param name is a synonym for another)
 * Allow MCA params and/or their synonyms to be marked as "deprecated"
   (printing out warnings if they are used)

These features have actually long been discussed/desired, and I had
some time in airports and airplanes recently where I could work in
this stuff on a standalone laptop.  So I did it.  :-)

This commit introduces these two new features, and then uses them to
register mpi_paffinity_alone as a non-deprecated synonym for
opal_paffinity_alone.  A few other random points in this commit:

 * Add a few error checks for conditions that were not checked before
 * Correct some comments in mca_base_params.h
 * Add a few comments in strategic places
 * ompi_info now prints additional information:
   * for any MCA parameter that has synonyms, it lists all the
     synonyms
   * synonyms are also output as 1st-class MCA params, but with an
     additional attribute indicating that they have a "parent"
   * all MCA param name (both "real" or "synonym") will output an
     attribute indicating whether it is deprecated or not.  A synonym
     is deprecated if it iself is marked as deprecated (via the
     mca_base_param_regist_syn() or mca_base_param_register_syn_name()
     functions) or if its "parent" MCA parameter is deprecated

9613b3176c Effectively revert the orte_output system and return to direct use of opal_output at all levels. Retain the orte_show_help subsystem to allow aggregation of show_help messages at the HNP.
After much work by Jeff and myself, and quite a lot of discussion, it has become clear that we simply cannot resolve the infinite loops caused by RML-involved subsystems calling orte_output. The original rationale for the change to orte_output has also been reduced by shifting the output of XML-formatted vs human readable messages to an alternative approach.

I have globally replaced the orte_output/ORTE_OUTPUT calls in the code base, as well as the corresponding .h file name. I have test compiled and run this on the various environments within my reach, so hopefully this will prove minimally disruptive.

828ae26d90 ORTE-level MCA params are defined in several places. Ompi_info cannot call orte_init due to an issue with the memory allocator, thus making it impossible for ompi_info to display all of the ORTE-level MCA params.
By consolidating them all into one function, ompi_info can call that function and register the desired variables. This also requires, however, that ompi_info call orte_output_init to avoid generating tons of error messages, so make that adjustment too. 

Fixes ticket #1314

In addition, orte_output has a race condition issue whereby calls to orte_output/verbose can occur prior to either the RML being defined/setup, or the HNP being defined. This latter occurs during the initialization of the orte_process_info structure. In both cases, there is no way orte_output can send the output to the HNP. Hence, the message must be simply output locally.

= ORTE Job-Level Output Messages =

Add two new interfaces that should be used for all new code throughout
the ORTE and OMPI layers (we already make the search-and-replace on
the existing ORTE / OMPI layers):

 * orte_output(): (and corresponding friends ORTE_OUTPUT,
   orte_output_verbose, etc.)  This function sends the output directly
   to the HNP for processing as part of a job-specific output
   channel.  It supports all the same outputs as opal_output()
   (syslog, file, stdout, stderr), but for stdout/stderr, the output
   is sent to the HNP for processing and output.  More on this below.
 * orte_show_help(): This function is a drop-in-replacement for
   opal_show_help(), with two differences in functionality:
   1. the rendered text help message output is sent to the HNP for
      display (rather than outputting directly into the process' stderr
      stream)
   1. the HNP detects duplicate help messages and does not display them
      (so that you don't see the same error message N times, once from
      each of your N MPI processes); instead, it counts "new" instances
      of the help message and displays a message every ~5 seconds when
      there are new ones ("I got X new copies of the help message...")

opal_show_help and opal_output still exist, but they only output in
the current process.  The intent for the new orte_* functions is that
they can apply job-level intelligence to the output.  As such, we
recommend that all new ORTE and OMPI code use the new orte_*
functions, not thei opal_* functions.

=== New code ===

For ORTE and OMPI programmers, here's what you need to do differently
in new code:

 * Do not include opal/util/show_help.h or opal/util/output.h.
   Instead, include orte/util/output.h (this one header file has
   declarations for both the orte_output() series of functions and
   orte_show_help()).
 * Effectively s/opal_output/orte_output/gi throughout your code.
   Note that orte_output_open() takes a slightly different argument
   list (as a way to pass data to the filtering stream -- see below),
   so you if explicitly call opal_output_open(), you'll need to
   slightly adapt to the new signature of orte_output_open().
 * Literally s/opal_show_help/orte_show_help/.  The function signature
   is identical.

=== Notes ===

 * orte_output'ing to stream 0 will do similar to what
   opal_output'ing did, so leaving a hard-coded "0" as the first
   argument is safe.
 * For systems that do not use ORTE's RML or the HNP, the effect of
   orte_output_* and orte_show_help will be identical to their opal
   counterparts (the additional information passed to
   orte_output_open() will be lost!).  Indeed, the orte_* functions
   simply become trivial wrappers to their opal_* counterparts.  Note
   that we have not tested this; the code is simple but it is quite
   possible that we mucked something up.

= Filter Framework =

Messages sent view the new orte_* functions described above and
messages output via the IOF on the HNP will now optionally be passed
through a new "filter" framework before being output to
stdout/stderr.  The "filter" OPAL MCA framework is intended to allow
preprocessing to messages before they are sent to their final
destinations.  The first component that was written in the filter
framework was to create an XML stream, segregating all the messages
into different XML tags, etc.  This will allow 3rd party tools to read
the stdout/stderr from the HNP and be able to know exactly what each
text message is (e.g., a help message, another OMPI infrastructure
message, stdout from the user process, stderr from the user process,
etc.).

Filtering is not active by default.  Filter components must be
specifically requested, such as:

{{{
$ mpirun --mca filter xml ...
}}}

There can only be one filter component active.

= New MCA Parameters =

The new functionality described above introduces two new MCA
parameters:

 * '''orte_base_help_aggregate''': Defaults to 1 (true), meaning that
   help messages will be aggregated, as described above.  If set to 0,
   all help messages will be displayed, even if they are duplicates
   (i.e., the original behavior).
 * '''orte_base_show_output_recursions''': An MCA parameter to help
   debug one of the known issues, described below.  It is likely that
   this MCA parameter will disappear before v1.3 final.

= Known Issues =

 * The XML filter component is not complete.  The current output from
   this component is preliminary and not real XML.  A bit more work
   needs to be done to configure.m4 search for an appropriate XML
   library/link it in/use it at run time.
 * There are possible recursion loops in the orte_output() and
   orte_show_help() functions -- e.g., if RML send calls orte_output()
   or orte_show_help().  We have some ideas how to fix these, but
   figured that it was ok to commit before feature freeze with known
   issues.  The code currently contains sub-optimal workarounds so
   that this will not be a problem, but it would be good to actually
   solve the problem rather than have hackish workarounds before v1.3 final.

dee561d29e Per recent off-list discussions about the build system, I have done
some cleanups and standardizations in the various */tools/*/ 
Makefile.am files.  This commit:

 * Somewhat simplify the tool Makefile.am's 
 * Makes the tool Makefile.am's consistent with each other (do similar
   actions in similar ways)
 * Update the tool Makefile.am's to remove old kruft that was required
   by older versions of AM (trunk requires AM >=1.10)
