* airtest got built as mv2test in the RASH config
* airtest and nailboardtest got build with profiling in Debug config
* airtest still had bogus WE config

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.

a94cc2ed78 New generic function landsize returns the total size of ranges in a land (if the land supports it). implement it for all land classes. 
The MVFF pool class doesn't have to maintain its free size any more: it can just call LandSize.
Move re-entrancy protection from CBS to Land. This allows us to remove some CBS functions. (But requires some adjustment in failoverDelete.)
In MVFF, do more checking of mvff->total.
