the pattern `for (x = ISC_LIST_HEAD(...); x != NULL; ISC_LIST_NEXT(...)` has been changed to `ISC_LIST_FOREACH` throughout BIND, except in a few cases where the change would be excessively complex. in most cases this was a straightforward change. in some places, however, the list element variable was referenced after the loop ended, and the code was refactored to avoid this necessity. also, because `ISC_LIST_FOREACH` uses typeof(list.head) to declare the list elements, compilation failures can occur if the list object has a `const` qualifier. some `const` qualifiers have been removed from function parameters to avoid this problem, and where that was not possible, `UNCONST` was used.
