Title: {SD}List [front|back] primitives

Re-opening.

Just some minor details:
* Adding void front|back(T value) for DList and DList.Range.
* A few missing ddocs in both.
* A few missing validity checks*.

enforcements have been introduced where missing, for consistency. These should (will) be replaced by asserts in a future (different) pull.
