MPITOOLS: Generate processor pairs in round-robin order.
...
The list of processor pairs in round-robin order should guarantee the
optimal MPI exchange between processors, i.e. that all processors will
be involved in the data exchange in the same time.

Revert "SOURCES: Rewrite resistive source terms."
...
This reverts commit 34f2871b350b207bfc9a4c1cb872da7d85a47040.
The new implementation based on curl produces numerical oscillation at
small scales.

SOURCES: Implement full viscous stress tensor.
...
The viscous source term can be expressed as the laplacian only in the
incompressible case (div V = 0) with uniform viscosity. If we have
compressibility or non-uniform viscosity, we need to use the full
viscous stress tensor.
This patch implements it.

IO: Format change for storing data blocks in restart files.
...
This format change is required to remove unnecessary allocation of large
arrays in order to store primitive and conservative variables in the
restart files. With this format change the memory limit of the half of
the available total memory is removed. However, in the case of use of
the data compression the sizes of restart files are typically large. The
compression ratio, however, can be improved by repacking the files using
the tools provided by the HDF5 libraries.

With the standard formatting, there are only two digits for the
exponent, however, the double precision numbers can have exponents down
to -308 and up to 308. That means that three digit exponents are
required to the number representation in the integral files.
