* thread.h: Include "list.h".
(struct thread) [! NDEBUG]: Add field futex_waiter_node.
[! NDEBUG]: Instantiate the futex_waiter list class.
(futex_waiters) [! NDEBUG]: Declare.
* server.c (futex_waiters) [! NDEBUG]: New variable.
(server_loop) [! NDEBUG]: If we don't get an RPC for a while,
dequeue all thread's enqueued on FUTEX_WAITERS and return EDEADLK.
When blocking a thread on a futex, add THREAD to FUTEX_WAITERS.
* object.c (object_wait_queue_dequeue) [! NDEBUG]: If
THREAD->WAIT_REASON is THREAD_WAIT_FUTEX, unlink THREAD from
FUTEX_WAITERS.

(futex_wake): Likewise.
* mutex.h (ss_mutex_lock): If FUTEX_WAIT returns failure, print
some debugging information.
