Remove hack from rnd_grain -- this was covering up a bug.
Base the AMC "large" segment determination on the requested object size, not the (rounded up) segment size.
Assert in the case where largeSize < extendBy: this has bad space performance.

AMC also uses MPS_KEY_LARGE_SIZE keyword argument to specify what size objects need to be to live on their own segment.

Old (undocumented) functions mps_{mv,mvff,mvt}_size and mps_{mv,mvff,mvt}_free_size are now macros for the new public functions.
New pool methods PoolTotalSize and PoolFreeSize, with implementations for public pool classes except SNC.
Coverage of the new functions in apss and mpmss for the manual pool classes, and in finaltest for the automatic pool classes.

Allocation into a generation now via PoolGenAlloc (not ChainAlloc).
The "top generation" logic is encapsulated in the function ChainGen.

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.)

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).

* 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.

Remove unreachable code:
* No need to have different debug options or structured allocation classes for different platforms.
* Don't use STATISTIC_BEGIN, use STATISTIC_STAT.
* #ifdef away the unused code in zmess.c for testing ControlAlloc failure.
* Remove unused code from the example Scheme interpreter.

Extract common code for size computations.
More accurate size computation using offsetof.
Macros for NailboardNewNails and NailboardClearNewNails.
Since level shift is constant (for now), use constant instead of structure slot.
Unroll NailboardSet.
Move NailboardIsResClientRange to poolamc where it belongs.
