1f517274f3 Cast all arguments to the writef function to make it easy to check that none of the necessary casts have been omitted.
New macro WriteFYesNo makes it easy to describe a Boolean.
Describe more structure elements for ABQ, Arena, Buffer, Format, MFS, Root, Seg.

88708ac00a Instead of creating one padding object for each reclaimed object in a nailed amc segment, create a padding object for each contiguous run of reclaimed objects, speeding up any future traversals of the segment.

9d1cec7942 Ensure that the amcss test case uses a wide range of arena grain sizes (by scaling up the whole allocation).
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.

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.

d3d2795fce 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).

9bb6b2f8be 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.
