zlib and bignum both contain unblocking functions which are async-signal-safe and do not require spawning additional threads. We can execute those functions directly in signal handlers without incurring overhead of extra threads, so provide C-API users the ability to deal with that. Other C-API users may have similar need. This flexible API can supercede existing uses of rb_thread_call_without_gvl and rb_thread_call_without_gvl2 by introducing a flags argument to control behavior. Note: this API is NOT finalized. It needs approval from other committers. I prefer shorter name than previous rb_thread_call_without_gvl* functions because my eyes requires big fonts.
