signal: do_sigtimedwait() needs retarget_shared_pending() ...
do_sigtimedwait() changes current->blocked and thus it needs
set_current_blocked()->retarget_shared_pending().
We could use set_current_blocked() directly. It is fine to change
->real_blocked from all-zeroes to ->blocked and vice versa lockless,
but this is not immediately clear, looks racy, and needs a huge
comment to explain why this is correct.
To keep the things simple this patch adds the new static helper,
__set_task_blocked() which should be called with ->siglock held. This
way we can change both ->real_blocked and ->blocked atomically under
->siglock as the current code does. This is more understandable.
