Before this patch, only the first waiting task will be listed in debug
command.
Now add the feature to list all waiting tasks for
sem/mutex/buf_queue/queue.

In the solution rfid_demo, the documentation about the RFID is
not clear enough. So directly using a better documentation instead
of writing it.

In the solution flower_demo, the documentation about the sensor DHT11 is
not clear enough.  So directly using a better documentation in CSDN
instead of writing it.
