Details: - Rewrote bli_init() and bli_finalize() with OpenMP critical sections for thread-safety. Also added lots of explanatory comments. - Renamed bli_init_safe() and bli_finalize_safe() with the _auto() suffix, and reimplemented for simplicity. Updated all invocations in BLAS compatibility layer to use _auto() suffix.
