George Bosilca 8119c970db Improve the connection algorithm for MX. There are 2 problems here:

- first we setup the connections in the begining with all the peers
- MX does not handle well the case where several peers make connections to the same
  destination simultaneously.

So I change the order in which we connect. First we compute our rank in the array,
then in a round-robin fashion we setup connection starting with our left neighboard.

This commit was SVN r8075.

Activate the protection against unavailable datatypes. They get a flag DT_FLAG_UNAVAILABLE. We check now this flag in all the send/recv operations via the macros on mpi/c/bindings.h.
