allow setting soname without suffix or prefix

Improve the performance of dasum and sasum when SMP is defined

Add reproducer test for crash after fork

Don't overwrite blas_thread_buffer if already set

See #2993 for an analysis

After a fork it is possible that blas_thread_buffer has already
allocated memory buffers: goto_set_num_threads does allocate those
already and it may be called by num_cpu_avail in case the OpenBLAS
NUM_THREADS differ from the OMP num threads.
This leads to a memory leak which can cause subsequent execution of BLAS
kernels to fail.
