Add build-time option for OMP scheduler; document MULTITHREAD_THRESHOLD range (#1620)
* Allow choosing the OpenMP scheduler and add range hint for GEMM_MULTITHREAD_THRESHOLD
* Amended description of GEMM_MULTITHREAD_THRESHOLD
to reflect #742 making it track floating point operations rather than matrix size

Zhang Xianyi 3617c22a56 Refs #294. Used pthread_atfork to avoid hang after a Unix fork.
The problem is the mutex we used in blas_server. Thus, we must clear
the mutex before the fork and re-init them at parent and child process.

If you used OpenMP, GOMP has the same problem by now. Please try other OpenMP
implemantation.
