72bef32e65 Convert the C++ Comm keyval creation and intercept callbacks to *not*
use the STL.  This is the first step in removing the STL from the C++
bindings (Solaris has 2 versions of the STL; if OMPI uses one and an
MPI application wants to use another, Bad Things happen).

The main idea is to wrap up the C++ callback function pointers and the
user's extra_state into our own struct that is passed as the
extra_state to the C keyval registration along with the intercept
routines in intercepts.cc.  When the C++ intercepts are activated,
they unwrap the user's callback and extra state and call them.

It got a little more complicated than that, however:

 * I realized that we were returning errors back from
   Comm::create_keyval() incorrectly, so I fixed that.
 * Instead of using STL maps to store associations, we now use an
   opal_list_t which has to be guaranteed to be initialized correctly
   and only once in a multi-threaded environment.
 * Because of whackyness in the C++ bindings, it is possible to call
   Comm::Create_keyval with C callbacks (!).  If both registered
   callbacks are C functions, then ensure to avoid all the C++
   machinery.

2b8af283de Add ability to completely turn off MPI one-sided support, so that users
can experiment with using ROMIO directly.

beb6dd1924 Include the C++ bindings from mpi.h in a way that doesn't require an extra
-I for ${includedir}/openmpi.  Solves many problems, and with just a tad
bit of hackery.  Don't know why I didn't just do this earlier.

a04c8eb39a - Bring over the visibility feature, for a finer symbol export control
via the visibility feature that is provided by some compilers.

  Per default this feature is disabled, to enable it you need to
  configure with --enable-visibility and obviously you need a compiler
  with visibility support. Please refer to the wiki for more information.

260f1fd468 Fixes trac:817
The C++ bindings were not tracking keyvals properly -- they were
freeing some internal meta data when Free_keyval() was called, not
when the keyval was actually destroyed (keyvals are refcounted in the
C layer, just like all other MPI objects, because they can live for
long after their corresponding Free call is invoked).  This commit
fixes this problem and several other things:

 * Add infrastructure on the ompi_attribute_keyval_t for an "extra"
   destructor pointer that will be invoked during the "real"
   constructor (i.e., when OBJ_RELEASE puts the refcount to 0).  This
   allows calling back into the C++ layer to release meta data
   associated with the keyval.
 * Adjust all cases where keyvals are created to pass in relevant
   destructors (NULL or the C++ destructor).
 * Do essentially the same for MPI::Comm, MPI::Win, and MPI:Datatype:
   * Move several functions out of the .cc file into the _inln.h file
     since they no longer require locks
   * Make the 4 Create_keyval() functions call a common back-end
     keyval creation function that does the Right Thing depending on
     whether C or C++ function pointers were used for the keyval
     functions.  The back-end function does not call the corresponding
     C MPI_*_create_keyval function, but rather does the work itself
     so that it can associate a "destructor" callback for the C++
     bindings for when the keyval is actually destroyed.
   * Change a few type names to be more indicative of what they are
     (mostly dealing with keyvals [not "keys"]).
 * Add the 3 missing bindings for MPI::Comm::Create_keyval().
 * Remove MPI::Comm::comm_map (and associated types) because it's no
   longer necessary in the intercepts -- it was a by-product of being
   a portable C++ bindings layer.  Now we can just query the C layer
   directly to figure out what type a communicator is.  This solves
   some logistics / callback issues, too.
 * Rename several types, variables, and fix many comments in the
   back-end C attribute implementation to make the names really
   reflect what they are (keyvals vs. attributes).  The previous names
   heavily overloaded the name "key" and were ''extremely''
   confusing.

1ba97181dc A number of MPI-2 compliance fixes for the C++ bindings:
* Added Create_errhandler for MPI::File
  * Make errors_throw_exceptions a first-class predefined exception
    handler, and make it work for Comm, File, and Win
  * Deal with error handlers and attributes for Files, Types, and Wins
    like we do with Comms - can't just cast the callbacks from C++
    signatures to C signatures.  Callbacks will then fire with the
    C object, not the C++ object.  That's bad.

6e1729cb93 Fixes trac:580
* Add MPI::Status methods Set_elements() and Set_cancelled()
 * Added a bunch of comments in various places in the MPI C++ bindings
   implementatio just to explain what's going on (because C++ can hide
   a lot from you)
 * Insert C++ callbacks for the MPI_Grequest callback functions
   registered by MPI::Grequest::Start().  These callbacks keep a
   little meta-data (created by Grequest::Start()) that allow the
   proper callback signatures from C (i.e., from ompi_grequest_<foo>()
   in libmpi.a -- C code), translate arguments as required, and then
   invoke the callbacks with proper C++ signatures (i.e., call
   user-defined callbacks with C++ function signatures).

fdc8f69b84 * need to include iostream as well as stdio.h when doing the tricks with
MPI::SEEK_* because iostreams (well, ios_base, but I don't think that
    should be included directly) can use SEEK_* as values in an enum, which
    means that 'const int' is bad for them.
  * Remove now useless comments in the cxx example programs
  * include iostream after mpi.h so that our examples work with other MPI
    implementations that don't try to be as friendly with the constants.

e7a7a64e4c Implement MPI::SEEK_{SET, END, POS} for the C++ bindings, working around
some issues with the C #defines SEEK_{SET, END, POS}.  The workaround
involves some hackery that should work in almost every common use case
for the C stdio constants (and all the legal issues of the MPI constants).
The one issue is that the C stdio constants are now const ints instead
of #defines, which means that #ifdef checks will fail for the constants.

Behavior can be disabled at either configure time or build time.

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)
