Using a STL map to keep in relation the C pointer with the C++ object
isn't that way more expensive that it is supposed to be ? The STL map
is just a hash table, it can be as optimized as you want, it's still
a hash table. How about using exactly the same mechanism as for the
Fortran handler ? It's cheap, it's based on an array, it's thread
save and we just reuse the code already there.

Log:
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.
