10.10 Backport of cleanup issues

[Katherine Marsden]

There are quite a few issues fixed in trunk that are titled "cleanup". I 
was thinking unless there is a real bug it does not make sense to 
backport them.  Please let me know if you see value in backporting 
these. Otherwise I will mark all the cleanup* issues 
derby_backport_reject10_10 this afternoon.
