Add a new queue implementation for OpenAFS. This has a similar calling
form as the current RX queue implementation, but is implementated using
type safe functions, and supports structures with multiple queue
headers. This permits threading a structure onto multiple queues at the
same time.
The eventual intention is that this queue implementation will replace
both rx_queue and the Unix cache manager afs_q.
