Summary:
Fixes T11836. See some prior discussion in T8376#120613.
The policy hint in headers in the UI is not exhaustive, and can not reasonably be exhaustive. For example, on a revision, it may say "All Users", but really mean "All users who can see the space this object is in and the repository it belongs to, plus the revision author and reviewers".
These rules are explained if you click (and, often, in the documentation), but "All Users" is still at least somewhat misleading.
I don't think there's any perfect solution here that balances the needs of both new and experienced users perfectly, but this change tries to do a bit better about avoiding cases where we say something very open (like "All Users") when the real policy is not very open.
Specifically, I've made these changes to the header:
- Spaces are now listed in the tag, so it will say `(S3 > All Users)` instead of `(All Users)`. They're already listed in the header, this just makes it more explicit that Spaces are a policy container and part of the view policy.
- Extended policy objects are now listed in the tag, so it will say `(S3 > rARC > All Users)` for a revision in the Arcanist repository which is also in Space 3.
- Objects can now provide a "Policy Codex", which is an object that represents a rulebook of more sophisticated policy descriptions. This codex can replace the tag with something else.
- Imported calendar events now say "Uses Import Policy" instead of, e.g., "All Users".
I've made these changes to the policy dialog:
- Split it into more visually separate sections.
- Added an explicit section for extended policies ("You must also have access to these other objects: ...").
- Broken the object policy rules into a "Special Rules" section (for rules like "you can only see a revision if you can see the repository it is part of") and an "Object Policy" section (for the actual object policy).
- Tried to make it a little more readable?
- The new policy dialogs are great to curl up with in front of a fire with a nice cup of cocoa.
I've made these changes to infrastructure:
- Implementing `PhabricatorPolicyInterface` no longer requires you to implement `describeAutomaticCapability()`.
- Instead, implement `PhabricatorPolicyCodexInterface` and return a `PhabricatorPolicyCodex` object.
- This "codex" is a policy rulebook which can set all the policy icons, labels, colors, rules, etc., to properly explain complex policies.
- Broadly, the old method was usually either not useful (most objects have no special rules) or not powerful enough (objects with special rules often need to do more in order to explain them).

Summary:
Ref T7703. See that task and inline for a bunch of discussion.
Briefly, when we run implicit policy rules ("to see a revision, you must also be able to see its repository") at query time, they don't apply to other viewers we might check later.
We do this very rarely, but when we do we're often doing it for a bunch of different viewers (for example, in Herald) so I don't want to just reload the object a million times.
Test Plan:
- Added and executed unit tests.
- Wrote a "flag everything" Herald rule, as in the original report in T7703, and no longer got "Unknown Object" flags on revisions.
- Rigged up a lot of cases in the web UI and couldn't find any inconsistencies, although this case is normally very hard to hit.

@chad is hitting an issue described in P961, which I think is this bug in PHP: https://bugs.php.net/bug.php?id=43200
Work around it by defining a "PHIDInterface" and having both "Flaggable" and "Policy" extend it, so that there is only one `getPHID()` declaration.
Test Plan: shrug~

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 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:
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.

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.
