b3d827b6fb Pool generations now refer directly to their generation (not via a chain and a generation number). 
Allocation into a generation now via PoolGenAlloc (not ChainAlloc).
The "top generation" logic is encapsulated in the function ChainGen.

e7d41a8fde Fix bugs in condemn logic: 
1. TraceStartCollectAll now condemns all segments in pools with AttrGC (not just pools attached to generation zero of some chain, as before).
2. ChainDeferral now looks at all generations in the chain, so that the chain is condemned if any generation's new size is greater than its capacity (not just generation zero, as before).
3. ChainCondemnAuto now condemns all generations up to and including the highest generation whose new size is greater than its capacity (rather than, as before, up to and excluding the lowest generation whose new size is lower than its capacity).
Update finaltest.c so that it has a mode in which it allocates in generation 1 of a chain and with the arena released so that the above fixes are tested. Remove the MPS_KEY_GEN workarounds from awlut and awluthe as these are no longer needed.

1. Blacken the segments again after scanning the roots, so that the roots can be walked again.
2. Don't cast RootGrey to a RootIterateFn -- the types are not compatible.
MMQA test function/122.c now passes.

6d923be672 Eventtxt no longer reports an error if there are multiple labels associated with an address. instead, it store all the labels encountered, and prints the one that was in force at the time of each event. 
Use the MPS to manage memory, not malloc/free.
Recommend sort before mpseventtxt and not afterwards (data is smaller; labelling is more accurate).

Don't try to detect when the MPS has made a "dynamic" collection. This is not reliable or maintainable.
