72ba071b4c Fix arenarootswalk: 
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).

ae09ed50c5 Fix amcssth -- don't try to test two incompatible features at the same time (see job003561). 
Set the commit limit in amcss and amcsshe so that we test that the MPS can live in a tight memory limit.
Don't try to detect when the MPS has made a "dynamic" collection. This is not reliable or maintainable.

e7a9e1e244 Make debugging pool implementation more flexible -- there's no longer a requirement for fencesize to be a multiple of the pool alignment, nor for freesize to be a divisor of the pool alignment. this makes it easy to write simple and portable debug options structures without having to mess about with mps_pf_align.
