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. This commit was SVN r13565.
