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).

ArenaDestroy fixed so that ChunkDestroy can go ahead even though the freeCBS has been torn down. Allows completion of test programs.

Not quite working yet. This code fails to unmap unused page table pages, and so triggers an assertion at chunk finish.

Spare pages are returned to the OS using the ring in roughly LRU order.
Only enough spare pages are returned to maintain hysteresis, rather than all of them.
Nearly ready to strip out the noSparePages bit table.

* Use const char * in places where we want to assign string constants.
Avoid warnings when compiling with -Wextra:
* Avoid if statement with empty body in amcsshe.c

tract.c -- fix more ChunkCache defects:
- drop never-read chunkCache->pageTableBase and pageTableLimit fields: they were used for ChunkOfSeg(), back when each SegStruct was actually a PageStruct is some chunk's PageStructTable; see VMArenaChunkOfSeg() in //info.ravenbrook.com/project/mps/branch/2001-08-13/trunk/src/arenavm.chttps://github.com/Ravenbrook/mps/issues/46
- there's no need for arena to initialise the chunk cache; this allows en/decache functions to be local to tract.c (ie. declared static)

arenavm.c -- on VMFree(), destroy any empty chunks (except the primary). (VMFree is not the ideal place to do it, but works for proof of concept).
tract.c -- fix ChunkCache defects:
- previously, if cache is empty (chunkCache->chunk == NULL) then other fields are *undefined*; but code looks at them anyway (!) without first checking chunkCache->chunk;
- change it (.chunk.empty.fields) so that, if cache is empty, other fields have defined values: cache-using code may look at them, and they are chosen so that no cache hit will occur.
--> this fixes crashing defect shown by changelist 170072
- AVERT(ChunkCache) in the many places it should be checked;
- use AVERT_CRITICAL in ChunkEncache, because it is called by ChunkOfAddr;
Also:
plan.txt -- notes on use of primary chunk.
config.h -- DIAG also in ci, please [Do not integ to master]
diag.c -- skip ChainCondemnAuto diag thanks
zcoll.c -- move printf announcing Destroying arena etc to just before, not just after, we do it.

arenavm.c: VMFree is okay for testing chunk-ret; though just sparePagesPurge() for now;
diag.c: show what we want for using zcoll to show chunk-ret:
VM_ix_Create/Destroy
TraceStart, excpet only briefly for dyn-crit (why=2) and not at all for minor
locus.c: no newline on "condemn gens" diag please
tract.c: ChunkDecache is BROKEN; just add AVER to catch this for now
vmix.c: VM_ix_Create_ok/VM_ix_Destroy (vmw3.c needs similar)
zcoll.c:
release after mps_arena_collect!!!
make, collect, make, collect, to show chunk-ret
10MB arena means many chunks
None of this is releaseable quality of course.

#define TractArena(tract). The broken definition worked because
it was always invoked with "TractPool(tract)". (Source-only change)
