helical_forcing_k_generator() added.
Now Helical forcing almost works. I just need scale to force per tiome step
correctly. The current formulation is wrong.

VERBOSE_PRINTING flag is now globally used in the whole program and should be used to suppress development/debugging-related printing. Also added comments to the new interface function acCheckDeviceAvailability and made it free from side effects.

Added tighter bounds for gcc and nvcc versions. There was a bit of an chicken-and-egg issue: we need gcc 6.0 in order to get bug 48891 (see gcc bugzilla) fixed, but cuda < 9 supports gcc only up to 5.3. This is not a perfect solution, f.ex. ubuntu 16.04 ships with gcc 5.4 but with the fix backported from later versions so in practice that would also work but is not accepted anymore.

Can move forcing vector information now from the host to device.
next step in to generate random waves in the CPU with a chosen degree of helicity etc.

Renamed old single-GPU-only headers in core/kernels to avoid confusion. Only kernels.cuh is used for reductions, integration and boundary conditions at the moment.

Fixed a compilation error when not using entropy. This is a temporary workaround. There is no model solution for hydro only, therefore autotesting will break if entropy is not used. Note: LINDUCTION, LENTROPY and other logical flags are duplicated in both astaroth.h and stencil_process.sps. These flags are not linked and there will be errors and weird behaviour if a flag is set in one file and not in another.
