The `diff_addremove()` and `diff_change()` functions set up and queue diffs, but do not return the `diff_filepair` added to the queue. In a subsequent commit, modifications to `diff_filepair` need to occur in certain cases after being queued. Since the existing `diff_addremove()` and `diff_change()` are also used for callbacks in `diff_options` as types `add_remove_fn_t` and `change_fn_t`, modifying the existing function signatures requires further changes. The diff options for pruning use `file_add_remove()` and `file_change()` where file pairs do not even get queued. Thus, separate functions are implemented instead. Split out the queuing operations into `diff_queue_addremove()` and `diff_queue_change()` which also return a handle to the queued `diff_filepair`.
