Message:

Reimplement waitq using thread_wait/wakeup

This adds a few functions to the thread API which can be
summarized as "stop running until woken up by others".
The ordering and context-switching concerns are thus yeeted
to this abstraction and waitq only deals with maintaining
the queues. Overall, this makes the control flow in waitq
much easier to navigate.
