Carpet: Use only one thread if OMP_NUM_THREADS is not set
Introduce a new value for the parameter Carpet::num_threads: when set to -2, and when the environment variable OMP_NUM_THREADS is not set, then only 1 thread is used instead of a system default.

As I mentioned I think this functionality should rather be not in Carpet, but Cactus itself. However, the parameter already existed, so I don't see a reason not to extend its value until this is provided by Cactus itself.
I didn't test the patch yet, but I have two things to note: the parameter value description contains two typos and the patch for Carpet also changes a line which has nothing to do with the openmp issue at hand. I suggest to make the latter a separate (trivial) commit.
