f906187add iterating over segments using the pool and segment rings, rather than scanning the tract table, which may be full of irrelevant tracts, especially when non-gc pools are large. see <https://info.ravenbrook.com/mail/2014/01/25/12-16-09/0/>.

33a73ce392 Non-working preferential allocation within a block of the cbs. 
This doesn't work because the splay tree can't cope with homing in on a node (that appears big enough) then being told that it isn't suitable (because it doesn't have space in the right zone).  The splay tree summary condition must be precise, as stated in the design.  The splay tree isn't suited to this kind of search.
