Giving up on 3D decomposition with CUDA-aware MPI. The MPI implementation on Puhti seems to be painfully bugged, the device pointers are not tracked properly in some cases (f.ex. if there's an array of structures which contain CUDA pointers). Going to implement 3D decomp the traditional way for now (communicating via the CPU). It's easy to switch to CUDA-aware MPI once Mellanox/NVIDIA/CSC have fixed their software.

Started the 3D decomposition branch. Four tasks: 1) Determine how to distribute the work given n processes 2) Distribute and gather the mesh to/from these processes 3) Create packing/unpacking functions and 4) Transfer packed data blocks between neighbors. Tasks 1 and 2 done with this commit.
