cleanup and simplify interrupt/shutdown handling

We now assume any non-zero timeout (not just infinite timeout)
is cancellable as well as interruptible.  This means
mog_idleq_wait will no longer retry blindly on EINTR.

Handling of explicit device refreshes and aio_threads
is now easier-to-understand and follow.
