The VMCompact diag was calculating the live percentage by dividing by condemned size. Don't do this if condemned is zero.

arenavm.c:

- diag on VMCompact after all client-requested traces, plus any others where we returned a chunk.
- show vmem change, and also trace cond, live / % / stuck(pip), notCond

arenavm.c -- move chunk-return into new function "VMCompact".
(also, in VMArenaFinish, null out arena->primary in VMArenaFinish, so it is not left dangling).

arena->class->compact: ArenaCompact, ArenaTrivCompact, VMCompact

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.

Hope to fix in time, but for now I need DIAG-out to work, so switch
to printf (yes, really, I know, sorry).
Also, only do DIAG-out in variety.di, to avoid damage to .ci.
So for now, remove DIAG_WRITEF and DIAG from arenavm and trace.
To test, add DIAG_PRINTF in trace.
