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.

Summary:
Ref T603. Several issues here:
1. Currently, `FileQuery` does not actually respect object attachment edges when doing policy checks. Everything else works fine, but this was missing an `array_keys()`.
2. Once that's fixed, we hit a bunch of recursion issues. For example, when loading a User we load the profile picture, and then that loads the User, and that loads the profile picture, etc.
3. Introduce a "Query Workspace", which holds objects we know we've loaded and know we can see but haven't finished filtering and/or attaching data to. This allows subqueries to look up objects instead of querying for them.
- We can probably generalize this a bit to make a few other queries more efficient. Pholio currently has a similar (but less general) "mock cache". However, it's keyed by ID instead of PHID so it's not easy to reuse this right now.
This is a bit complex for the problem being solved, but I think it's the cleanest approach and I believe the primitive will be useful in the future.

Ref T3775 (discussion here). Ref T2625.
T3775 presents two problems:
# Existing tools which linked to `/differential/active/epriestley/` (that is, put a username in the URL) can't generate search links now.
# Humans can't edit the URL anymore, either.
I think (1) is an actual issue, and this fixes it. I think (2) is pretty fluff, and this doesn't really try to fix it, although it probably improves it.
The fix for (1) is:
- Provide a helper to read a parameter containing either a list of user PHIDs or a list of usernames, so `/?users[]=PHID-USER-xyz` (from a tokenizer) and `/?users=alincoln,htaft` (from an external program) are equivalent inputs.
- Rename all the form parameters to be more digestable (`authorPHIDs` -> `authors`). Almost all of them were in this form already anyway. This just gives us `?users=alincoln` instead of `userPHIDs=alincoln`.
- Inside ApplicationSearch, if a request has no query associated with it but does have query parameters, build a query from the request instead of issuing the user's default query. Basically, this means that `/differential/` runs the default query, while `/differential/?users=x` runs a custom query.

If the final result set is built out of multiple pages, it's in the wrong order overall, with each page in the correct order in sequence. Instead, reverse everything at the end. This also simplifies construction of queries.
- `AphrontCursorPagerView` would always render a "<< First" link when paging backward, even if we were on the first page of results.
- Add a filtering hook to let queries perform in-application pre-policy filtering as simply as possible (i.e., without maintaing their own cursors over the result sets).

Summary:
I'm trying to make progress on the policy/visibility stuff since it's a blocker for Wikimedia.
First, I want to improve Projects so they can serve as policy groups (e.g., an object can have a visibility policy like "Visible to: members of project 'security'"). However, doing this without breaking anything or snowballing into a bigger change is a bit awkward because Projects are name-ordered and we have a Conduit API which does offset paging. Rather than breaking or rewriting this stuff, I want to just continue offset paging them for now.
So I'm going to make PhabricatorPolicyQuery extend PhabricatorOffsetPagedQuery, but can't currently since the `executeWithPager` methods would clash. These methods do different things anyway and are probably better with different names.
This also generally improves the names of these classes, since cursors are not necessarily IDs (in the feed case, they're "chronlogicalKeys", for example). I did leave some of the interals as "ID" since calling them "Cursor"s (e.g., `setAfterCursor()`) seemed a little wrong -- it should maybe be `setAfterCursorPosition()`. These APIs have very limited use and can easily be made more consistent later.

Summary:
Provides a basic start for access policies. Objects expose various capabilities, like CAN_VIEW, CAN_EDIT, etc., and set a policy for each capability. We currently implement three policies, PUBLIC (anyone, including logged-out), USERS (any logged-in) and NOONE (nobody). There's also a way to provide automatic capability grants (e.g., the owner of an object can always see it, even if some capability is set to "NOONE"), but I'm not sure how great the implementation feels and it might change.
Most of the code here is providing a primitive for efficient policy-aware list queries. The problem with doing queries naively is that you have to do crazy amounts of filtering, e.g. to show the user page 6, you need to filter at least 600 objects (and likely more) before you can figure out which ones are 500-600 for them. You can't just do "LIMIT 500, 100" because that might have only 50 results, or no results. Instead, the query looks like "WHERE id > last_visible_id", and then we fetch additional pages as necessary to satisfy the request.
The general idea is that we move all data access to Query classes and have them do object filtering. The ID paging primitive allows efficient paging in most cases, and the executeOne() method provides a concise way to do policy checks for edit/view screens.
We'll probably end up with mostly broader policy UIs or configuration-based policies, but there are at least a few cases for per-object privacy (e.g., marking tasks as "Security", and restricting things to the members of projects) so I figured we'd start with a flexible primitive and the simplify it in the UI where we can.
Test Plan: Unit tests, played around in the UI with various policy settings.
