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.
trace.c: (comment) explain .verify.segsummary

conjecture .stat.fwdbuf-survives: a forwarding buffer can survive
traceStart and flip while remaining attached to the same segment.
(Previously, the diagram implicitly used ".simplify.detach-all-fwdbuf" :-).
State some truths, conjectures, and some simplifications-that-may-be-lies.

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.
