DIAG-out an ArenaDescribe.

arena.c: turn off call from ArenaDescribe to GlobalsDescribe,
because it outputs too much stuff (perhaps this change should be
reverted later).

arenavm.c: add DIAG(ArenaDescribe) in VMChunkCreate;
amcss.c: make initial-size to mps_arena_create comically small,
to prompt VMChunkCreates and occasional MPS_RESERVE_BLOCK: 7's

poolamc.c: Count the loops of amcScanNailed.
If amcScanNailed looped, ss.unfixedSummary is
not accurate, so move all of the ScanStateSummary into
ss.fixedSumamry, so that trace.c's .verify.segsummary
does not erroneously fail.
This fixes job001548.

have failed .verify.segsummary. Count the loops. Show whether it
wasTotal.
AMCSegSketch: correct it to show stalo and neo the right way round.

find out what the summary really is, and check against SegSummary().
Initially, check this before each AMCScan. This check does *not* fire
when the unfixed assert does; see new a2kAllobjs.txt logfile.

Save sketches (abzSketchTotal and abzSketchTotalPrev) in amcseg,
which get Described when unfixedSummary is wrong: let's see whether
there's a pattern to the way the previous summary was created.

seg.c: SegDescribe: say "buffer: NULL" if it is (rather than saying nothing).
buffer.c: BufferDescribe: now interprets buffer->mode for you.
poolamc.c: amcSegCheck: check Nailboard present onlyif SegNailed for some trace;
AMCSegDescribe: correct SEG_SUPERCLASS (so we see GCSeg fields);
say whether seg is Mobile, Boarded (there's a nailboard), or Stuck;
clearer Map symbols, and print a key for them.
