Summary: Remarkup rules can not safely use arbitrary text in tag attributes,
because it may include tokens which are later replaced. Precedence rules
should prevent this in general. Use flat text assertions and adjust precedence
rules in cases where they may not prevent tokens from appearing in attributes.

This does some backend cleanup of the tile stuff, and some general cleanup of other application things:
- Users who haven't customized preferences get a small, specific set of pinned applications: Differential, Maniphest, Diffusion, Audit, Phriction, Projects (and, for administrators, Auth, Config and People).
- Old tile size methods are replaced with `isPinnnedByDefault()`.
- Shortened some short descriptions.
- `shouldAppearInLaunchView()` replaced by less ambiguous `isLaunchable()`.
- Added a marker for third-party / extension applications.

Summary:
While we mostly have reasonable effective object accessibility when you lock a user out of an application, it's primarily enforced at the controller level. Users can still, e.g., load the handles of objects they can't actually see. Instead, lock the queries to the applications so that you can, e.g., never load a revision if you don't have access to Differential.
This has several parts:
- For PolicyAware queries, provide an application class name method.
- If the query specifies a class name and the user doesn't have permission to use it, fail the entire query unconditionally.
- For handles, simplify query construction and count all the PHIDs as "restricted" so we get a UI full of "restricted" instead of "unknown" handles.
Test Plan:
- Added a unit test to verify I got all the class names right.
- Browsed around, logged in/out as a normal user with public policies on and off.
- Browsed around, logged in/out as a restricted user with public policies on and off. With restrictions, saw all traces of restricted apps removed or restricted.

This is meaningless in JIRA since you have no idea what it's talking about. Instead, publish like this:

Additionally, supplement it with a URI, so the total story text we publish is:

Ref T2852. Depends on D6302. This now creates, destroys, and synchronizes subtasks.
- After finishing the parent task stuff, we pull a list of all known subtasks.
- We load all those subtasks.
- If we fail to load any, we delete their objects and edges on the Phabricator side.
- Of the remaining subtasks, we find subtasks for users who aren't related to the object any more and delete them in Asana and locally (for example, if alincoln is removed as a reviewer, we delete his subtask).
- For all the related users, we either synchronize their existing task or create a new one for them.
- Then we write edges for any new tasks we added.
This doesn't handle a few weird edge cases in any specific way:
- If a subtask is moved under a different parent, we ignore it.
- If a new subtask is created that we don't know about, we ignore it.
- If a subtask we know about is deleted, we just respawn it. This is consistent with "DON'T EDIT THESE". You can force sync to stop by deleting the parent.
Addititionally:
- Make the "don't edit" warning more compelling and visceral.
Test Plan:
- Kind of ran it a bit.
- There are like 3,000 edge cases here so this is hard to test exhaustively.

Ref T2852. Give OAuth providers a formal method so you can ask them for tokens; they issue a refresh request if necessary.
We could automatically refresh these tokens in daemons as they near expiry to improve performance; refreshes are blocking in-process round trip requests. If we do this for all tokens, it's a lot of requests (say, 20k users * 2 auth mechanisms * 1-hour tokens ~= a million requests a day). We could do it selectively for tokens that are actually in use (i.e., if we refresh a token in response to a user request, we keep refreshing it for 24 hours automatically). For now, I'm not pursuing any of this.
If we fail to refresh a token, we don't have a great way to communicate it to the user right now. The remedy is "log out and log in again", but there's no way for them to figure this out. The major issue is that a lot of OAuth integrations should not throw if they fail, or can't reasonably be rasied to the user (e.g., activity in daemons, loading profile pictures, enriching links, etc). For now, this shouldn't really happen. In future diffs, I plan to make the "External Accounts" settings page provide some information about tokens again, and possibly push some flag to accounts like "you should refresh your X link", but we'll see if issues crop up.
