We are really suffering from now ulist's implementation, some developers
gave their try, and i just gave some of my ideas for things:
1. use list+rb_tree instead of arrary+rb_tree
2. add cur_list to iterator rather than ulist structure.
3. add seqnum into every node when they are added, this is
used to do selfcheck when iterating node.
I noticed Zach Brown's comments before, long term is to kick off
ulist implementation, however, for now, we need at least avoid
arrary from ulist.

I like it, can we use CONFIG_BTRFS_DEBUG or whatever it's called for the
seqnum check to make the struct a bit smaller in the normal case? Thanks,
Josef
