Details: - Switched the small block allocator (sba), as defined in bli_sba.c and bli_apool.c, to static initialization of its internal mutex. Did a similar thing for the packing block allocator (pba), which appears as global_membrk in bli_membrk.c. - Commented out bli_membrk_init_mutex() and bli_membrk_finalize_mutex() to ensure they won't be used in the future. - In bli_thrcomm_pthreads.c and .h, removed old, commented-out cpp blocks guarded by BLIS_USE_PTHREAD_MUTEX.
