Summary:
Ref T13266. See <https://discourse.phabricator-community.org/t/notification-page-throws-unrecoverable-fatal-error/2651/>.
The "notifications" query currently uses offset paging for no apparent reason (just a legacy issue?), so some of the paging code is only reachable internally.
- Stop it from using offset paging, since modern cursor paging is fine here (and Feed has used cursor paging for a long time).
- Fix the non-offset paging to work like Feed.
Also:
- Remove a couple of stub methods with no callsites after cursor refactoring.
Test Plan:
- Set things up so I had more than 100 notifications and some in the first 100 were policy filtered, to reproduce the issue (I just made `FeedStory` return `NO_ONE` as a visibility policy).
- Applied the patch, notifications now page cleanly.
- Verified that "Next Page" took me to the right place in the result list.
