Andy Green 74fddbc09e cancel_service: change to event-loop agnostic implementation ... - Add platform helpers for pipe creation. - Change the direct-to-fds implementation to create a wsi for each pt and use the normal apis to bind it to the event loop. - Modifiy context creation and destroy to create and remove the event pipe wsis. - Create the event pipe wsis during context create if using the default poll() event loop, or when the other event loops start otherwise. - Add handler that calls back user code with LWS_CALLBACK_EVENT_WAIT_CANCELLED This patch allows you to call `lws_cancel_service(struct lws_context *context)` from another thread. It's very cheap for the other thread to call and is safe without locking. Every use protocol receives a LWS_CALLBACK_EVENT_WAIT_CANCELLED from the main thread serialized normally in the event loop.		2017-11-26 19:16:17 +08:00
