Added padding to param name buffers to make them have NUM_*_PARAMS+1 elements. This should satisfy some strict compilation checks.

Major improvement: uniforms can now be set to default values. The syntax is the same as for setting any other values, f.ex. 'uniform Scalar a = 1; uniform Scalar b = 0.5 * a;'. Undefined uniforms are still allowed, but in this case the user should load a proper value into it during runtime. Default uniform values can be overwritten by calling any of the uniform loader funcions (like acDeviceLoadScalarUniform). Improved also error checking. Now there are explicit warnings if the user tries to load an invalid value into a device constant.

Simplified the include directory. Everything is now in only two headers: astaroth.h and astaroth_utils.h. Removed old and unused stuff. user.h is unused in standalone but might be used with Pencil Code, so left that intact.

Various improvements to the MPI-GPU implementation, but linking MPI libraries with both the host C-project and the core library seems to be a major pain. Currently the communication is done via gpu->cpu->cpu->gpu.

Added overloads for getting and setting various parameters. However, the compiler mangles the names which is not good for a cross-platform library so the functions are commented out for now. Sadly _Generic, which would solve everything, from C11 is not available in C++.

Reviewed the Astaroth interface. Now there's a clear distinction between synchronous and asynchronous functions. For basic usage, we provide a set of functions that are always safe to call (acIntegrate, acLoad, etc), but because of this, must be quite restricted in the sense that f.ex. the whole mesh must be loaded at once and computations cannot be executed concurrently on multiple GPUs. For more advanced users we provide asynchronous functions (such as acLoadWithOffset). Since we cannot know how the asynchronous functions are called (for example, when the integration step has been fully completed and the halos of neighboring subgrids can be safely communicated between GPUs), the responsibility of synchronization must be left to the user. In the existing implementations we currently use only the basic "safe" set of functions (except in renderer.cc), so the existing functionality has not been changed with these latests commits. Autotests also pass.

Overhaul to the user-defined parameters done: All logical switches, parameters and vertex buffer handles are now defined in a single header file (the default location is acc/mhd_solver/stencil_defines.h). This header is used when preprocessing the DSL sources and is linked to the include/ directory when calling scripts/compile_acc.sh. astaroth.h is now used for configuring internal stuff only and should not be modified by users

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).

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).
