Subject: [PATCH] Fix: define _TASK_THREAD_SAFE for TaskScheduler

the TaskScheduler runs in the context of a FreeRTOS thread/task. there
are other such threads (MQTT client and web server in particular). to
allow changing TaskScheduler task properties from different threads, we
need to enable the use of a mutex to protect the TaskScheduler.
