Added the equations for hydro only for both CPU and GPU. NOTE: NOT RIGOROUSLY CHECKED FOR CORRECTNESS. I just took the equations used with entropy and removed the terms which included entropy and magnetic fields

Removed all defines from the stencil assembly and processing files and moved them to the new stencil_defines header. There were spaces after some linebreaks which were removed when I autoformatted the code and that's why there seems to be more changes that there actually is.

Linked the defines used by the DSL and astaroth.h. Now f.ex. LENTROPY has to be set only once in acc/mhd_solver/stencil_defines.h and it is propagated throughout the whole project. The name for stencil_defines.h is not final and may change if I come up with a better name. In any case, there is now a standard header associated with each DSL solver where the user can set defines, and declare arrays (VTXBUF_LNRHO) and device constants (uniforms).

Worked around a compiler bug in CUDA 9.1, which caused an "Internal Compiler Error (codegen): "there was an error in verifying the lgenfe output!". Apparently the compiler got confused by overloaded is_valid() if the input parameter was not passed as a reference in both cases.

Modified user.h such that astaroth compiles with Pencil Code. Note that this is a temporary fix: we should ultimately set the default parameters for all the logical switches in astaroth.h and let the user redefine them at will, either with the DSL or with user.h

Autoformatted with clang-format. Clang-format does not support indented defines as far as I know, so this will have to do. The alternative would be not to use autoformatting at all (or some other tool).

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.

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.

Enabled toy forcing by default for testing purposes. Note that there are two LFORCING switches at the moment: one in astaroth.h and one in acc/mhd_solver/stencil_process.sps. The switches are not linked and the tests fail or simulations generate unexpected results if both switches are not set to the same value. This will be fixed in the near future.
