Show auditors in commit history table

Hack to load auditor names and show them in the table.
Disable table Remarkup syntax, it bugs out in the preview
Do not modify memory limit in index.php

Throws errors on hardened PHP configurations.
Mark self-audits differently in history table
Infrastructure changes to support scoped symbols

Summary:
 - import_project_symbols supports an optional extra field, which is the
   context of the symbol.
 - Symbol query can take a symbol argument, either as a parameter or a
   URL component (so you can now jump nav to `s Zerg/rush`, for
   example).
 - Conduit method not yet updated. Will do that later.

NOTE: Not providing a context is distinct from providing an empty
context, because an empty context stands for top-level context, i.e.
functions and classes for PHP. It will not find class methods, etc. It
is possible that we should use some weird token that could not normally
be a context name to stand in for empty context.

Test Plan: Do a bunch of symbol searches.

Rename "IDPaged" to "CursorPaged", "executeWithPager" to "executeWith[Cursor|Offset]Pager"

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.

Remove setOwners() from PhabricatorProjectQuery

Summary: I'm deprecating the concept of "owners" (which currently has no meaning in the actual application) in favor of policy-based controls. Remove the ability to query by it.

Test Plan: Grepped for setOwners(), no relevant hits. Browsed the project listing.

Add getMemberPHIDs() and loadMemberPHIDs() to PhabricatorProject

Summary:
I want to:

  - move the membership storage to edges
  - remove the concepts of "roles" (which are decorative text only) and "owners" (which will be replaced with policy-based controls)

This moves us a step closer to that by reducing the use of ProjectAffiliation outside of the class.

Test Plan: Loaded project profile. Called `project.query`. Joined and left a project.

Remove subprojects from the Projects UI and API

Summary:
These are currently useless and confusing (they have no application impact), and should be migrated to edges if we want to restore them in some form.

I left the actual storage so this doesn't destroy any data, it just removes all traces of this feature from the UI.
