d8e81ae3c3 Abolishing the redundant generation to zone map in the vm arena, and replacing it with chainalloc, which allocates segments within a generation. 
Generations from different chains will no longer share the same zone sets, and will not be collected together.  To get this behaviour, use the same chain, as documented.

f748ad2b28 Eliminating type puns on scan states, location dependencies, and allocation points through the mps interface.
