What is changed and the side effects?

Changed:

1. Not to support the tracing of bthread in TASK_STATUS_JUMPING status and just return an error msg like below, instead of waiting for jumping.
2. Taskmeta has its lock for waiting for tracing, to avoid starvation of bthread jumping caused by new tracing.
3. WaitForTracing acquire the lock, indicating that tracing is complete, so no condition variable is needed.

Side effects:

• Performance effects:

• Breaking backward compatibility:

I have an irrelevant doubt. The cur_ending parameter seems not used?
static void sched_to(TaskGroup** pg, TaskMeta* next_meta, bool cur_ending);

cur_ending was used before, but is no longer used. You can delete it.
