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.

We make sure that we're not working with a global policy that just sets the title correctly. Otherwise we have a PHID to work with and set the handle as required.

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 resolves lots of double escaping.
We changed most of `phutil_render_tag(, , $s)` to `phutil_tag(, , $s)` which means that `$s` is now auto-escaped.
Also `pht()` auto escapes if it gets `PhutilSafeHTML`.

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:
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.

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.
