3d1db4eab6 Use cbs subclasses to implement the fast-find and find-in-zones features. this avoids the need to control behaviour by passing booleans, and it means that there is no wasted space in the cbs block structure when these features are not used. 
Bring splay tree design up to date; add missing diagrams; move it to the "current" section of the manual.

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.
