The scope of this part is to make this API more coherent with History.jsm input will also accept URL objects, output will always contain URL objects. dates will always be Date objects. update and remove will now take an optional callback and resolve to a bool. While this may look strange for update, since it acts on a single item, it will allow us to make it batch multiple updates in future, without touching the API signature. on invalid input, all methods will throw immediately rather than rejecting later.

Marco, I splitted out this requirement for bug 1068009.
