queue.3: Split the page into smaller pages

Hi,

I recently (Linux man-pages 5.9) divided queue(3) into a set of pages:
circleq(3), list(3), slist(3), stailq(3), tailq(3), and queue(7) (we kept a link queue(3)->queue(7)).

As the Linux man-pages copied the page from you, I kept the BSD license, so that you may copy the improvements back without problems if you want.

However, the new pages use a different syntax, so you may have to do some changes.

And please, if you feel something needs to be improved from those pages, write back ;-)

Cheers,

Alex
