Revert parts of commit a85c8a "runtime/io.c: Explicitly signal setting of _stp_exit_flag" and commit 46ac9e "Remove _stp_ctl_work_timer from module transport layer". Introduce a new test wake_up.exp that shows a deadlock when sending cmd messages and waking up the reader immediately. Renamed _stp_ctl_write to _stp_ctl_send, which can be called from everywhere. Rename _stp_ctl_send to _stp_ctl_send_notify that can be called from user context in the transport layer itself (this will immediately notify any readers). Document all places that use _stp_ctl_send_notify directly to clarify why that is safe.
