Summary:
Currently, we're showing projets in reverse order (Z..A) because most cursor pagers go from high IDs to low IDs.
Allow sequence to be reversed; reverse it.
Also simplify some query/paging stuff.
Test Plan: Set page size to 1, paged back and forth.

Summary:
- Allow PolicyQuery to require specific sets of capabilities other than "CAN_VIEW", like edit, etc. The default set is "view".
- Add some convenience methods to PolicyFilter to test for capabilities.
Test Plan: Viewed pastes, projects, etc. Used other stuff in future diff.

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:
I'm trying to make progress on the policy/visibility stuff since it's a blocker for Wikimedia.
First, I want to improve Projects so they can serve as policy groups (e.g., an object can have a visibility policy like "Visible to: members of project 'security'"). However, doing this without breaking anything or snowballing into a bigger change is a bit awkward because Projects are name-ordered and we have a Conduit API which does offset paging. Rather than breaking or rewriting this stuff, I want to just continue offset paging them for now.
So I'm going to make PhabricatorPolicyQuery extend PhabricatorOffsetPagedQuery, but can't currently since the `executeWithPager` methods would clash. These methods do different things anyway and are probably better with different names.
This also generally improves the names of these classes, since cursors are not necessarily IDs (in the feed case, they're "chronlogicalKeys", for example). I did leave some of the interals as "ID" since calling them "Cursor"s (e.g., `setAfterCursor()`) seemed a little wrong -- it should maybe be `setAfterCursorPosition()`. These APIs have very limited use and can easily be made more consistent later.
Test Plan: Browsed around various affected tools; any issues here should throw/fail in a loud/obvious way.

- 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.
