Summary:
Ref T603. I want to let applications define new capabilities (like "can manage global rules" in Herald) and get full support for them, including reasonable error strings in the UI.
Currently, this is difficult for a couple of reasons. Partly this is just a code organization issue, which is easy to fix. The bigger thing is that we have a bunch of strings which depend on both the policy and capability, like: "You must be an administrator to view this object." "Administrator" is the policy, and "view" is the capability.
That means every new capability has to add a string for each policy, and every new policy (should we introduce any) needs to add a string for each capability. And we can't do any piecemeal "You must be a {$role} to {$action} this object" becuase it's impossible to translate.
Instead, make all the strings depend on //only// the policy, //only// the capability, or //only// the object type. This makes the dialogs read a little more strangely, but I think it's still pretty easy to understand, and it makes adding new stuff way way easier.
Also provide more context, and more useful exception messages.
Test Plan:
- See screenshots.
- Also triggered a policy exception and verified it was dramatically more useful than it used to be.

Summary:
Ref T603. This could probably use a little more polish, but improve the quality of policy error messages.
- Provide as much detail as possible.
- Fix all the strings for i18n.
- Explain special rules to the user.
- Allow indirect policy filters to raise policy exceptions instead of 404s.
Test Plan: See screenshots.

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.

- `kill_init.php` said "Moving 1000 files" - I hope that this is not some limit in `FileFinder`.

- Comment `phutil_libraries` in `.arcconfig` and run `arc liberate`.

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.
