bf80a3a11d Mps br/padding: new pooltraceendmethod: do end-of-trace work 
Tracer calls PoolTraceEnd() when the trace is TraceFINISHED.
 AbstractPoolClass uses PoolTrivTraceEnd -- a NOOP. [mpm.h, mpmst.h, mpmtypes.h, pool.c, poolabs.c]
 AMC overrides with AMCTraceEnd, to emit diagnostic on how well the trace went! [poolamc.c]

1c3940b99a Mps br/padding zcoll.c: change bigsmall() test to bigdropsmallambig() -- 
creates a big object and drops the ref to it, followed by a small object and keeps an ambig ref to it (to nail the AMCSeg it is in).
Loops 100 times.  This is for testing job001811 changes.

ed1f97ac9f Mps br/padding: more diagnostic for how padding survives a collection. 
More diag:
  - new traceSetSignalEmergency;
  - new AMCFix_amcSegCreateNailboard and AMCHeaderFix_amcSegCreateNailboard
    (note: the other, unreported, route to becoming boarded is because of a (mutator) buffer);
  - in traces: show SegBase and zone;
   - in TraceStart: show genZoneSets;
   - in amcReclaimNailed: show cbpip and cbpad.
 zcoll.c:
   - sizemethod 1 to Make command: occasionally makes >1MiB objects;
   - declare root_table all MPS_RANK_AMBIG.

d5379b26ef Mps master (integ from br/timing): 
Messages:
  - _gc_start and _gc now always ControlAlloc'd, new lifecycle, much better code.  Fixes job001989.
  - New test zmess, which tests generating and getting MPS messages.  Tests job001989, and also job001658 (subsumes fin1658a.c).
  - New file traceanc.c, for ancillary code extracted from trace.c.
  - Diag (.variety.di) at ArenaDestroy, say if message queue non-empty.
Randomize() and rnd() now much better seeding, improved (more random) generator, thorough verification, faster.
New test zcoll (incomplete), which tests MPS collections, their timing, and feedback about them.
MPS_ALERT_COLLECTION_START/STOP renamed as MPS_ALERT_COLLECTION_BEGIN/END
