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]
