I noticed that there is a disproportionate number of calls to sorting routine
gk_sort, computing k+G indices (igk). This is VERY DANGEROUS: the ordering of
degenerate k+G shells is unpredictable and any operation that changes k even
by even the least significant bit may lead to a slightly different ordering.

variables for the "world" MPI communicator. The latter are to be found in
world_comm instead. mp_global should be used only to start and to end the
various parallelization levels. Many small but harmless changes: a few
variables removed or moved to another module in most cases.
