Removed the O2 flag since cmake still defines the O3 flag in CMAKE_CXX_FLAGS_RELEASE and it's confusing which one gcc chooses if both O3 and O2 are passed during compilation. If the issue was the march=native flag then this should also work on Tiara

Standalone now uses O2 optimization level instead of O3. Also removed -march=native since this causes issues if the program is compiled on a different architecture than it is run on. Since we do not do heavy arithmetic on the host side and the host code is not performance-critical part of the code, -march-native is not very useful anyways

Added sum reduction. NOTE: Scalar sum does not pass the automated test but vector sum does. I couldn't see anything wrong with the code itself and I strongly suspect that the failures are caused by loss of precision due to summing a huge amount of numbers of different magnitudes. However I'm not yet completely sure. Something like the Kahan summation algorithm might be useful if the errors are really caused by fp arithmetic.

CONFIG_PATH is now supplied by ac_mkbuilddir. While using would be a bit more idiomatic, ASTAROTH_CONF_PATH is probably safer since ac_mkbuilddir.sh does the copying and knows for sure what the correct path is.

Added declaration of constants for sink particle. Still in the process of understanding how values are passed, but I've realized how physical equations are defined in stencil_process.sps and in principle I can replicate that for sink particle(which will mostly be gravity).

Apparently my edit this time was unsuccessful, tons of error messeages showed up when I ran "make -j" command in working directory. However this commit is mainly for education purposes, it's so that Miikka (main) and others can see what I changed easily and can use as teaching reference.

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.
