Summary:
There are quite a few tests in Arcanist, libphutil and Phabricator that do something similar to `$this->assertEqual(false, ...)` or `$this->assertEqual(true, ...)`.
This is unnecessarily verbose and it would be cleaner if we had `assertFalse` and `assertTrue` methods.
Test Plan: I contemplated adding a unit test for the `getCallerInfo` method but wasn't sure if it was required / where it should live.

Summary:
Ref T2222. Currently, Differential has a fairly hairy piece of logic to parse object lists, like `Reviewers: alincoln, htaft`. Extract, generalize, and cover this.
- Some of the logic can be simplified with modern ObjectQuery stuff.
- Make `@username` the formal monogram for users.
- Make `list@domain.com` the formal monogram for mailing lists.
- Add test coverage.
Test Plan:
- Ran unit tests.
- Called `differential.parsecommitmessage` with a bunch of real-world inputs and got sensible results.

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. Currently, we render handles the user doesn't have permission to see in a manner identical to handles that don't exist. This is confusing, and not required by policies (which restrict content, but permit knowledge that an object exists).
Instead, render them in different styles. Bad/invalid objects look like:
Unknown Object (Task)
Restricted objects look like:
[o] Restricted Task
...where `[o]` is the padlock icon.
Test Plan:
{F71100}
{F71101}
It's possible this renders weird somewhere, but I wasn't immediately able to find any issues. Yell if you see something.

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.
Test Plan: Looked at pastes, macros, mocks and projects as a logged-in and logged-out user.

Summary: I think the old thing did this, but this makes queries a bit less ridiculous. For example, `secure.phabricator.com` currently issues a query for 664 handles on my task list, but only 73 of them are unique (basically, all the projects plus all the authors). This proably is slightly good for performance, but mostly makes the "Services" tab manageable.
Test Plan: Looked at Maniphest and some other pages, saw handles and objects where they were expected to be.

Summary:
Ref T603. Moves to detangle and optimize how we apply policies to filtering objects. Notably:
- Add a short circuit for omnipotent users.
- When performing project filtering, do a stricter check for user membership. We don't actually care if the user can see the project or not according to other policy constraints, and checking if they can may be complicated.
- When performing project filtering, do a local check to see if we're filtering the project itself. This is a common case (a project editable by members of itself, for example) and we can skip queries when it is satisfied.
- Don't perform policy filtering in ObjectQuery. All the data it aggregates is already filtered correctly.
- Clean up a little bit of stuff in Feed.
Test Plan: Pages like the Maniphest task list and Project profile pages now issue dramatically fewer queries.

Summary: Ref T2715. `PhabricatorObjectQuery` can theoretically bypass policies on its side-channel result set. This can't actually happen in practice because all the loading mechanisms are filtered, but provide a general way to implement side channel results safely.

Summary:
Ref T2715. This is pretty straightforward, I think. Notes:
- Long term, I want to replace `PhabricatorObjectHandleData` with `PhabricatorObjectQuery` and `PhabricatorHandleQuery`. The former's name is a relic of old Facebook stuff and unusual now that everything else uses normal queries.
- I simplified the amount of work applications need to do in order to populate handles. The should just need to set names and URIs in most cases.
Test Plan: Used `phid.lookup` and `phid.query` to load slowvote handles. Browsed around to load other handles.

Summary:
See discussion in T2715. Currently, PHIDs are all hard coded in the PHID application. In the long run, we need to move them out into actual applications.
A specific immediate issue is Releeph, which uses a very very old and very broken mechanism to inject PHIDs in a way that only sort of works.
Moving forward, every PHID type will be provided by a `PhabricatorPHIDType` subclass, which will manage loading it, etc.
This also moves toward cleaning up the "load objects by name" (where "name" means something like `D12`) code, which is an //enormous// mess and spread across at least 4-5 callsites.
Test Plan: Used `phid.lookup` and `phid.query` to load Slowvotes.
