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.

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)
