The anti-entropy feature has never actually worked. We've been
talking about removing it or replacing it for ages, but haven't
had a concrete motivation.
But the anti-entropy interface is the sole user of several components
of the Tx interface, and now that we're trying to replace that
interface, being able to drop those components has some appeal, so
let's remove the one thing that used them, in the hopes that this
will simplify life.
This also lets us drop ForEach and ForEachRange, which were
barely used at all. The one surviving usage (CSV export) can be
handled by using the container iterator we already have, and
making ContainerCallback exported so we can use it to just call
things for every bit.
We have code to correctly fill in cell.BitN when a leaf cell already
exists but isn't of the correct sort, but not to handle the case where
it already exists and *is* a BitmapPtr, but doesn't necessarily have
the right BitN value.
We have some tests that cover stuff like the DumpDot functionality,
but we don't need them to actually write to stdout during ordinary
testing. Dump to buffers which we politely ignore. Yes, we could have
used a dummy writer, but this way it's super easy to display the
contents if we find ourselves suddenly caring.
i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;
fi
else
rm $file.tmp;
fi
done
```

- the sync.Pool default uses little memory under CI.
- arena approach provides ability to control the maximum memory
used by rbf Cursors.
- cursor caching is adjustable with --rbf-cursor-cache
currently 0 by default (meaning use sync.Pool), and
larger than 0 meaning use an arena of this size.
With the arena, 20 or less is needed to pass CI.
- rbf test suite runs ~ 4x faster
- kitchen sink ingest test runs 16% faster.
- report TotalAlloc in CALLSTATs
fixes#1105
- fix a bug in computing leafCell.BitN in a run after a bit Remove
- shrink bitmaps on remove
- util_test.go has Cursor.DebugSlowCheckAllPages to verify;
used by cursor_test.go
