x86, ds: add leakage warning
Add a warning in case a debug store context is not removed before
the task it is attached to is freed.
Remove the old warning at thread exit. It is too early.
Declare the debug store context field in thread_struct unconditionally.
Remove ds_copy_thread() and ds_exit_thread() and do the work directly
in process*.c.
