0ee4d7ca06 Indirect formatted scanning through the scanstate. 
This will allow us to reuse the scanning protocol with an arbitrary area
scanning function (replacing traceFormatScan) in order to implement
formatted object walking without an extra segment method.

Don't insist on scanning only grey segments: we want to be able to
reuse the scan protocol for walking, when the segments are black.

60bf7320e2 Document the event parameters. 
Split event ArenaAccess into ArenaAccessBegin and ArenaAccessEnd to avoid the need for the count field.
New events SegReclaim and SegScan.
Delete some redundant events: AMCFinish (PoolFinish), AMCFix, AMCFixForward, AMCFixInPlace (TraceFix), AMCGenCreate (GenInit), AMCGenDestroy (GenFinish), AMCInit (PoolInitAMC), AMCReclaim (SegReclaim), AMCScanBegin, AMCScanEnd (SegScan), ArenaWriteFaults (ArenaAccessBegin), PoolInitMV, TraceScanSeg (SegScan).
Add result code field to events ArenaAllocFail, CommitLimitSet, SegAllocFail.
Remove arena field from events PoolInitAMS, PoolInitMFS, PoolInitMVFF (already appeared in generic PoolInit event).

7f7822d4ab Segment class gcseg no longer implements hardware barriers; these are implemented by new subclass mutatorseg, which is now used everywhere that gcseg was used formerly. the idea is that in a future change mrgrefseg will inherit from gcseg instead of mutatorseg.

d8a5c865ba Since we know that a segment belongs to a pool with a format at the point where we call segwalk, it makes sense to pass the format.
