Move APPEND_TO_BLOCKED_QUEUE from cmm to C

The I/O and delay blocking primitives for the non-threaded way
currently access the blocked_queue and sleeping_queue directly.

We want to move where those queues are to make their ownership clearer:
to have them clearly belong to the I/O manager impls rather than to the
scheduler. Ultimately we will want to change their representation too.

It's inconvenient to do that if these queues are accessed directly from
cmm code. So as a first step, replace the APPEND_TO_BLOCKED_QUEUE with a
C version appendToIOBlockedQueue(), and replace the open-coded
sleeping_queue insertion with insertIntoSleepingQueue().
