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)

This change will be integrated but ignored (-ay) to the gg-epcore/union sources, so that they retain HopeNames.
