conversion function are more complex and costly than a simple memcpy. Therefore,
we want to decrease as much as possible the usage of these functions.
We now check not only th HOMOGENEOUS flag on the datatype or convertor, but the
bits indicating a type is in use. If a communication transfert a type having the
same representation on both peers we can use the optimized version of the conversion.
In same time we build a more accurate conversion table for each master convertor,
based on the minimum differences between the 2 architectures.
