Benjamin Valentin b5ea78ad47 core/msg: make msg_avail() return 0 on no queue ... For the caller there should be no difference if there is no message in the queue and if there can't be a message in the queue. The current API works as one would expect if there is a message queue, but once called from a thread that does not have a message queue configured, code that does while (msg_avail()) will end up in an infinite loop. Remove this foot-gun from the API by making the return value of msg_avail() independend of the availability of a message queue.		2021-11-29 12:04:16 +01:00
