Add 32-bit int methods to BdfList and BdfDictionary.

We use these a lot so it's useful to have built-in support.

Also refactor BdfList and BdfDictionary so the getters that take default values behave like the other getters. This simplifies the semantics and allows duplicated code to be removed.

Add comprehensive tests for BdfList and BdfDictionary.
