wasm32-emscripten does not support exceptfds and requires NULL. Python now passes NULL instead of a fdset pointer when the input list is empty. This works fine on all platforms and might even be a tiny bit faster. Signed-off-by: Christian Heimes <christian@python.org>

Post-merge review: LGTM :-) If tomorrow we discover a platform which really requires a non-NULL pointer, we can fix that platform but keep the new behavior on most platforms. IMO passing NULL is perfectly fine. |
