The fix for #1864 in r20926 caused gcc to emit some warnings. Also,
Jeff Squyres pointed out parallel bugs in mpi_type_create_keyval and
mpi_win_create_keyval.
This commit was SVN r20950.

The EXTRA_STATE parameter is passed by reference, and thus should be
dereferenced before it is stored. Similarly, the stored value should
be passed by reference to the copy and delete routines.
This fixes trac:1864.

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.

- 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)
