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. This cleans up an existing callsite in the policy filter, and opens up some stuff in the future.
Some policy objects don't have real PHIDs:
PhabricatorTokenGiven
PhabricatorSavedQuery
PhabricatorNamedQuery
PhrequentUserTime
PhabricatorFlag
PhabricatorDaemonLog
PhabricatorConduitMethodCallLog
ConduitAPIMethod
PhabricatorChatLogEvent
PhabricatorChatLogChannel
Although it would be reasonable to add real PHIDs to some of these (like `ChatLogChannel`), it probably doesn't make much sense for others (`DaemonLog`, `MethodCallLog`). Just let them return `null`.
Also remove some duplicate `$id` and `$phid` properties. These are declared on `PhabricatorLiskDAO` and do not need to be redeclared.
Test Plan: Ran the `testEverythingImplemented` unit test, which verifies that all classes conform to the interface.

Summary:
Ref T3903. Ref T603. We currently overreact to invalid policies. Instead:
- For non-omnipotent users, just reject the viewer.
- For omnipotent users, we already shortcircuit and permit the viewer.
- Formalize and add test coverage for these behaviors.
Also clean up some strings.
The practical effect of this is that setting an object to an invalid policy (either intentionally or accidentally) doesn't break callers who are querying it.
Test Plan:
- Created a Legalpad document and set view policy to "asldkfnaslkdfna".
- Verified this policy behaved as though it were "no one".
- Added, executed unit tests.

Summary:
Ref T603. Adds clarifying text which expands on policies and explains exceptions and rules. The goal is to provide an easy way for users to learn about special policy rules, like "task owners can always see a task".
This presentation might be a little aggressive. That's probably OK as we introduce policies, but something a little more tempered might be better down the road.
Test Plan: See screenshot.

Summary:
Daemons (and probably a few other things) need to make queries without having a real user. Introduce a formal omnipotent user who can bypass any policy restriction.
(I called this "ominpotent" rather than "omniscient" because it can bypass CAN_EDIT, CAN_JOIN, etc. "Omnicapable" might be a better word, but AFAIK is not a real word.)
Test Plan: Unit tests.

Summary:
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).
Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.

- Allows projects to be set as policies.
- Allows Paste policies to be edited.

Summary:
A few goals here:
- Slightly simplify the Query classtree -- it's now linear: `Query` -> `OffsetPagedQuery` (adds offset/limit) -> `PolicyQuery` (adds policy filtering) -> `CursorPagedPolicyQuery` (adds cursors).
- Allow us to move from non-policy queries to policy queries without any backward compatibility breaks, e.g. Conduit methods which accept 'offset'.
- Separate the client limit ("limit") from the datafetch hint limit ("rawresultlimit") so we can make the heurstic smarter in the future if we want. Some discussion inline.
Test Plan: Expanded unit tests to cover offset behaviors.

Differential Revision: https://secure.phabricator.com/D2238
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.
