1. "#ifdef CHECKLEVEL > CheckLevelMINIMAL" was bogus: the #ifdef should have been #if, but even then it would not be right, because in the CHECKLEVEL_DYNAMIC configuration, CHECKLEVEL is a variable rather than a preprocessor constant. So use the condition defined(AVER_AND_CHECK_ALL) instead.
2. The final CHECKL(addr == seg->limit) only makes sense if the loop was executed.
3. The variables used by the loop need to be inside the #if to avoid warnings about unused variables.
4. Add reference to the job from a comment.

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.

* CONFIG_POLL_NONE (because the user-visible consequence is that polling is no longer supported; was CONFIG_PROTECTION_NONE).
* DISABLE_LOCKS (was THREAD_SINGLE).
* DISABLE_SHIELD (was THREAD_SINGLE && PROTECTION_NONE)
* DISABLE_REMEMBERED_SET (was PROTECTION_NONE)
When the shield is disabled, ArenaLeave asserts that there are no busy traces, and ArenaPoll is a no-op.
By having functions implemented using the corresponding macro, we can avoid duplicated code, and avoid testing DISABLE_SHIELD in global.c.
Remove all remaining references to MPS_PROD_EPCORE.

It's OK to call SegSetGrey on a segment with an empty rank set so long as you are not actually setting it to be grey for any traces, so correct the AVER accordingly.

This was the result of noticing a large number of SetSetGrey events that set the segment to the same greyness when scanning ambiguous references.

Abolishing event formats. Each event now has its own structure.
Event parameters are now written directly into the event buffer, rather than being copied twice.

seg.c: SegDescribe: say "buffer: NULL" if it is (rather than saying nothing).
buffer.c: BufferDescribe: now interprets buffer->mode for you.
poolamc.c: amcSegCheck: check Nailboard present onlyif SegNailed for some trace;
AMCSegDescribe: correct SEG_SUPERCLASS (so we see GCSeg fields);
say whether seg is Mobile, Boarded (there's a nailboard), or Stuck;
clearer Map symbols, and print a key for them.
