nproc: support nested OMP_NUM_THREADS, and OMP_THREAD_LIMIT * lib/nproc.c (parse_omp_threads): A new function refactored from num_processors() to support parsing both of the above environment variables. (num_processors): Prefer using omp_get_num_threads() with [_OPENMP] to accurately reflect the current OpenMP nesting level. Also support the OMP_THREAD_LIMIT environment variable to limit the max value determined from OMP_NUM_THREADS. * modules/nproc: Depend on minmax header. Suggested by Oliver Heimlich.
