Summary:
Ref T4589. When you look at a file, we load attached objects in order to run the "you can see this if you can see any attached object" policy check.
However, right now the subquery inherits the "throw on filter" flag from the parent query. This inheritance makes sense in other cases[1], but because this is an "ANY" rule it does not make sense here. In practice, it means that if the file is attached to several objects, and any of them gets filtered, you can not see the file.
Instead, explicitly drop the flag for this subquery.
[1] Sort of. It doesn't produce wrong results in other cases, but now that I think about it might produce a less-tailored error than it could. I'll look into this the next time I'm poking around.
Test Plan:
- Viewed an "All Users" file attached to a private Mock.
- Prior to this patch, I incorrectly received an exception when the Mock was loaded. This is wrong; I should be able to see the file because the policy is "All Users".
- After the patch, I can correctly view the file, just not the associated mock.

Summary:
`PhabricatorPolicyFilter` has a bug right now where it lets through objects incorrectly if:
- the query requests two or more policies;
- the object satisfies at least one of those policies; and
- policy exceptions are not enabled.
This would be bad, but there's only one call in the codebase which satisfies all of these conditions, in the Maniphest batch editor. And it's moot anyway because edit operations get another policy check slightly later. So there is no policy/security impact from this flaw.
(The next diff relies on this behavior, which is how I caught it.)
Test Plan:
- Added a failing unit test and made it pass.
- Grepped the codebase for `requireCapabilities()` and verified that there is no security impact. Basically, 99% of callsites use `executeOne()`, which throws anyway and moots the filtering.

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.

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:
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. Ref T3551. Ref T603. This does a few things, but they're all sort of small:
- We commonly use a `getX()` / `attachX()` pattern, but have very similar code in the `getX()` method every time. Provide a convenience method to make this pattern easier to write.
- We use `willFilterPage()` in many queries, but it currently is called with zero or more results. This means we have a lot of "if no results, return nothing" boilerplate. Make it call only for one or more results.
- Implement `PhabricatorPolicyInterface` on `ReleephBranch`. A branch has the same policy as its project.
- Implement `ReleephBranchQuery`.
- Move the branch PHID type to application PHID infrastructure.
Test Plan: Browsed Releeph. Used `phid.query` to query branch PHIDs.

This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).

Summary:
Provides a simple way for policy-aware queries to pre-filter results without needing to maintain separate cursors, and fixes a bunch of filter-related edge cases.
- For reverse-paged cursor queries, we previously reversed each individual set of results. 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).
Test Plan: Made feed randomly prefilter half the results, and paged forward and backward. Observed correct result ordering, pagination, and next/previous links.
