mps br/vmem: simple-chunk-return:

arenavm.c:
   - M_whole, M_frac: print count of bytes as Megabytes
   - 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

 mpm.c -- new "$3" format for 0-padding 3-char-wide field, for thousandths of a MB

 zcoll.c -- try some new parameters for tests

 diag.c -- just VMCompact diag
