+ * Fixed computation of timings for MPI_Send, MPI_Recv but possibly also others
+ We've found a bug that prevented SMPI to account for MPI_Send, MPI_Recv
+ and others (in some cases) in a correct way. That is, the smpi/os, smpi/or
+ values were ignored in some cases. The timings of these functions can now
+ be significantly different.

- Synchronous send/recv: easier and hopefully faster since the
logic is handled in the maestro process directly now

GRAS new features and improvements:

+ * New module mechanism where user code can use per process globals [Mt]
This is similar to gras_userdata_*() functions, but for libraries. It
factorize some code developped over and over in the examples and AMOK.
It has still to be documented and used (only amok/peermanagement is
converted for now).

Exception occurring on server-side are propagated back to client (!).
API CHANGE: the callback changed their prototype. Change:
- Don't use it for receive since we send data sizes and data on the
same stream, so we wouldn't be able to chain large amount of chunks
before having to flush the stuff to read the size.

It modifies (simplifies) all XBT and GRAS API.
MSG API keeps unchanged (exceptions raised by XBT are catched from
within MSG and masked with existing error handling facilities)
* Add xbt_os_time(). As the rest of xbt/portability, this is not public
for users. Instead, each programming environment (GRAS, MSG,...) use it
when needed to provide such a feature to users.
