Added WIP stuff for the Astaroth DSL compiler rewrite. Once this branch is finished only a single source file will be needed (file ending .ac). This revision is needed to decouple absolutely all implementation-specific stuff (f.ex. AC_dsx) from the core library and make life easier for everyone. The plan is to provide a standard library header written in the DSL containing the derivative operations instead of hardcoding them in the CUDA implementation.

Modified the syntax of writing real-valued literals with the DSL. Casts are not needed any more: f.ex. 1.0 is implicitly cast to AcReal. The syntax is now more consistent: reals must be explicitly written as a.b, where a and b are some integers. IMPORTANT: Previously the shorthands a. and .b were allowed, not anymore. Using those shorthands will result in a compilation error

Preprocessing writes the intermediate output to *.preprocessed files. This makes debugging various DSL syntax errors much easier since the line number in the error corresponds to the line numbers in these files.

acc is now built with cmake instead of the old build script. This was mainly done to fix compilation on Puhti where I had problems linking flex even though it is available. As an added bonus the code is now safer to build since all dependencies are now rigorously tracked by cmake and make, and f.ex. change in the compiler now forces also the whole library to be rebuilt (which is the behaviour we want)

The Astaroth Code Compiler (acc) is now built with cmake. Additionally, make is now used to generate the CUDA headers from DSL sources. The headers are also properly regenerated whenever a DSL file has been changed. With this commit, the DSL is now seamlessly integrated to the library and we no longer need complicated scripts to figure out the correct files. The current workflow for using custom DSL sources is to pass the DSL module directory to cmake, f.ex. cmake -DDSL_MODULE_DIR=/acc/mhd_solver. Note that the path must be absolute or then given relative to the CMakeLists.txt directory. f.ex cd build && cmake -DDSL_MODULE_DIR=../acc/mhd_solver does not work. CMake then takes all DSL files in that directory and handles the rest.

New feature: ScalarArray. ScalarArrays are read-only 1D arrays containing max(mx, max(my, mz)) elements. ScalarArray is a new type of uniform and can be used for storing f.ex. forcing profiles. The DSL now also supports complex numbers and some basic arithmetic (exp, multiplication)

DSL now 'feature complete' with respect to what I had in mind before the summer. Users can now create multiple kernels and the library functions are generated automatically for them. The generated library functions are of the form acDeviceKernel_<name> and acNodeKernel_<name>. More features are needed though. The next features to be added at some point are 1D and 2D device constant arrays in order to support profiles for f.ex. forcing.

The previous attempt (dsl_feature_completeness_2019-08-23) to enable arbitrary kernel functions was a failure: we get significant performance loss (25-100%) if step_number is not passed as a template parameter to the integration kernel. Apparently the CUDA compiler cannot perform some optimizations if there is a if/else construct in a performance-critical part which cannot be evaluated at compile time. This branch keeps step_number as a template parameter but takes rest of the user parameters as uniforms (dt is no longer passed as a function parameter but as an uniform with the DSL instead).
