Implement the new readahead method in btrfs.  Add a readahead_page_batch()
to optimise fetching a batch of pages at once.

readahead_page_batch() isn't added in this patch anymore.

Otherwise this looks good to me, although I don't feel confident
enough to give a Reviewed-by for btrfs code.

Review is on my todo so the series is not blocked on that.
