d7d04e024c Size class structures (mps_sac_class_s) are public, so should have names starting with "mps_" (these were removed incorrectly in change 179383).

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.

88626830d8 Alignment is now configurable for mv pools using mps_key_align. 
MVFF and MVT support alignments down to FreelistMinimumAlignment.
For MVFF and MVT, alignments that are too small are rounded up automatically, to make it easier to write portable programs.

2f61fea487 Amc/amcz subclass test needs to be other way round now. 
Smoke tests for AMCZ -- add it to amcss, amcsshe, amcssth, finaltest and walkt0.
Smoke tests for LO -- add it to walkt0.
Fix finaltest for AMC and AWL -- need to allocate in generation 0 to get prompt finalization. (Also fix MMQA test function/51.c.)

bcea6812fc Improve control over checking: 
1. Where Type is a pointer type with a signature, replace CHECKL(TypeCheck(val)) with CHECKD(Type, val).
2. Where Type is a pointer type with no signature, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val).
3. Where Type is a pointer type with a signature, but the structure is not visible at point of checking, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val). Reference <design/check/#.hidden-type>
4. Make BTCheck extern and use it where possible.
5. Replace AVER(TypeCheck(val)) with AVERT(Type, val).

fd07236307 Tidy-up of attributes and pool classes: 
* Bring design up to date.
* New function PoolHasAttr encapsulates attribute checking.
* Abstract classes are abstract and mustn't be checked.
* The dummy pool class in fotest needs a size.
* Abstract pool classes null out methods that they can't provide a generic implementation for, to force subclasses to provide one.
* New function PoolTrivFramePopPending provides a generic implementation of that method.
* Rename PoolNoFreeWalk to PoolTrivFreeWalk since it has NOOP rather than NOTREACHED.
* Check that AttrMOVINGGC implies AttrGC.
* Remove unimplemented attributes (BUF_RESERVE, BUF_ALLOC, INCR_RB, INCR_WB, PM)
* AMC now inherits from AMCZ instead of the other way round. This is simpler: AMC adds features to AMCZ rather than AMCZ taking features away (and not quite getting it right).
* Similarly, LO inherits from AbstractSegBufPoolClass + PoolClassMixInCollect so that it doesn't have to clear AttrSCAN and the scan methods.
* Fix bug in MFSCheck -- mustn't check unroundedUnitSize >= UNIT_MIN since small unit sizes are rounded up to UNIT_MIN.
* Don't see AttrFREE in MRG (since no free method is supplied).
* Check AttrSCAN systematically (in PoolScan and SegCheck) rather than opportunistically in TraceStart and TraceQuantum.
