Description

When sending large buffers consisting of non-contiguous datatypes via the zero copy API, we want to perform multiple rget/rput calls for each contiguous part.
Currently, DDT does not have an interface for iterating over the the contiguous parts of a non-contiguous datatype, so for now we just copy the send buffer into a contiguous buffer first.
