Allow commits to be associated with projects and associated goodies

Summary:
- Commit detail view
 - List of projects
 - "edit" action which takes the user to a simple form where they can only add / remove projects.
-  Integrated the project relationship into the commit search indexer
 - fixed a bug from D790; it seems you must select the column if you're going to join against it later. Without this change searching for author or projectfails 100% for me.

Test Plan: added and removed projects. verified appropriate projects showed up in detail and edit view. searched for commits by project and found the ones I was supposed to...!

Extend PhabricatorPolicyQuery from PhabricatorOffsetPagedQuery

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.

Add PhabricatorOwnersPackageQuery

Summary:
This is a step toward unearthing Project queries enough that I can make them policy-aware. Right now, some ProjectQuery callsites do not have reasonable access to the viewer. In particular, Owners packages need to issue Project queries because we allow projects to own packages and resolve project members inside of some package queries.

Currently, we have a very unmodern approach to querying packages, with a large number of one-off static load methods:

  PhabricatorOwnersPackage::loadAffectedPackages()
  PhabricatorOwnersPackage::loadOwningPackages()
  PhabricatorOwnersPackage::loadPackagesForPaths()
  PhabricatorOwnersOwner::loadAllForPackages()
  PhabricatorOwnersOwner::loadAffiliatedUserPHIDs()
  PhabricatorOwnersOwner::loadAffiliatedPackages()
  ConduitAPI_owners_query_Method::queryAll()
  ConduitAPI_owners_query_Method::queryByOwner()
  ConduitAPI_owners_query_Method::queryByAffiliatedUser()
  ConduitAPI_owners_query_Method::queryByPath()

We should replace `PhabricatorOwnersOwner` with an Edge and move all of these calls to a Query class. I'm going to try to do as little of this work as I can  for now since I'm much more interested in getting a functional policy implementation into other applications, but ProjectQuery needs to be policy-aware before I can do that and I need to dig some at least some of the callsites out enough that I can get a viewer in there without making the code worse than it is.

This adds a PhabricatorOwnersPackageQuery class and removes one callsite of one of those static methods.

I also intend to dissolve the two separate concepts of an "owner" (direct owner) and an "affiliated user" (indirect owner via project membership) since I think we're always fine with "affiliated users" owners.

Test Plan: Loaded home page / audit tool, which use the modified path. Ran queries manually via script. Made sure results included directly owned packages and packages owned through project membership.

Update symbol generation scripts

Summary:
Scripts now return scoped symbols -- in particular, PHP class constants, fields, and methods. ctags gives some for other languages.

(Turns out XHPAST doesn't support traits. But no one uses traits anyway so it's probably fine.)

I couldn't find a list of the context types ctags uses (class/struct/union/enum/maybe others?), so the context code just ignores that. Also, it uses a blacklist for the symbol type instead of a whitelist because there are a ton, they vary by language, and I didn't want to unintentionally exclude anything (P480).

Test Plan: Scrape symbols from arcanist and phabricator. Upload them to sandbox. Search for things.

Make projects policy-aware

Summary: We managed to move enough Owners stuff aside to make this reasonable; make projects implement the policy interface and projectquery use cursor-based paging.

Test Plan:
  - Grepped for ProjectQuery callsites.
  - Created an audit comment.
  - Used `project.query` to query projects.
  - Loaded homepage.
  - Viewed Maniphest task list, grouped by project.
  - Viewed project list.
  - Created / edited project.
  - Browsed Owners.

Summary: See discussion in D3078 for why I've separated this. Pretty sure it's not quite ready yet -- I want to build a couple of things on it so we have a better idea of what we need (autoincrement ID? <factType, objectA, epoch> primary key? objectB column? valueZ?) and don't need to do a ton of schema patches.
