Summary:
- Store project members in edges.
- Migrate existing members to edge storage.
- Delete PhabricatorProjectAffiliation.
- I left the actual underlying data around just in case something goes wrong; we can delete it evenutally.
Test Plan:
- Ran migration.
- Created a new project.
- Joined and left a project.
- Added and removed project members.
- Manually called PhabricatorOwnersOwner::loadAffiliatedUserPHIDs() to verify its behavior.

- Use edges to store this data.
- Migrate old data.
- Fix some warnings with generating feed stories about Aux and Edge transactions.
- Fix a task-task edge issue with "Create Subtask".
Test Plan:
- Migrated data, verified reivsions showed up.
- Attached and detached tasks to revisions and vice versa.
- Created a new revision with attached tasks.
- Created a subtask.

Summary:
blogs are collections of posts. a blog also has metadata like a name, description and "bloggers" that can edit the metadata of the blog and contribute posts.
changes include the post edit flow where bloggers can now select which blogs to publish to. also made various small tweaks throughout the UI to make things sensical and clean as the concept of blogs is introduced.
there's edges powering this stuff. bloggers <=> blogs and posts <=> blogs in particular.
Test Plan:
made blogs, deleted blogs, tried to make blogs with no bloggers. all went well.
verified ui to publish only showed up for public posts, published posts to blogs, un-published posts to blogs, re-published posts to blogs, deleted posts and verified they disappeared from blogs.

Differential Revision: https://secure.phabricator.com/D3003
Summary: See D3006. Move this data to the edge store.
Test Plan:
- Created dependencies, migrated, verified dependencies were preserved.
- Added new dependencies, they worked.

Maniphest Tasks: T1162
Differential Revision: https://secure.phabricator.com/D3007
Summary:
- Use edges to store "X depends on Y" information in Maniphest.
- Show both "Depends On" and "Dependent Tasks".
- Migrate all the old edges.
Test Plan:
- Added some relationships, migrated, verified they were preserved.
- Added some new valid relationships, verified tasks got updated with sensible transactions and sent reasonable emails.
- Tried to add a cycle, got an ugly but effective error.

Differential Revision: https://secure.phabricator.com/D3010
Summary:
Certain types of things we should be storing in edges (notably, Task X depends on Task Y) should always be acyclic. Allow `PhabricatorEdgeEditor` to enforce this, since we can't correctly enforce it outside of the editor without being vulnerable to races.
Each edge type can be marked acyclic. If an edge type is acyclic, we perform additional steps when writing new edges of that type:
- We acquire a global lock on the edge type before performing any reads or writes. This ensures we can't produce a cycle as a result of a race where two edits add edges which independently do not produce a cycle, but do produce a cycle when combined.
- After performing writes but before committing transactions, we load the edge graph for each acyclic type and verify that it is, in fact, acyclic. If we detect cycles, we abort the edit.
- When we're done, we release the edge type locks.
This is a relatively high-complexity change, but gives us a simple way to flag an edge type as acyclic in a robust way.
Test Plan: Ran unit tests.

Maniphest Tasks: T1162
Differential Revision: https://secure.phabricator.com/D2940
Summary:
- See D2741.
- When EdgeEditor performs edits, emit events.
- Listen for Maniphest edge events and save the changes as transactions.
- Do all this in a reasonably generic way that won't take too much rewriting as we use edges more generally.
Test Plan: Attached and detached commits from tasks, saw reasonable-looking transactions spring into existence.

- Comment `phutil_libraries` in `.arcconfig` and run `arc liberate`.
NOTE: `arc diff` timed out so I'm pushing it without review.

Maniphest Tasks: T1103
Summary: Use Edges to attach Commits and Tasks. Note, no "edit attached commits" interface from tasks yet since the search backend needs a little work to list commits in a sensible way.

Maniphest Tasks: T904
Differential Revision: https://secure.phabricator.com/D2105
Summary:
We have a lot of cases where we store object relationships, but it's all kind of messy and custom. Some particular problems:
- We go to great lengths to enforce order stability in Differential revisions, but the implementation is complex and inelegant.
- Some relationships are stored on-object, so we can't pull the inverses easily. For example, Maniphest shows child tasks but not parent tasks.
- I want to add more of these and don't want to continue building custom stuff.
- UIs like the "attach stuff to other stuff" UI need custom branches for each object type.
- Stuff like "allow commits to close tasks" is notrivial because of nonstandard metadata storage.
Provide an association-like "edge" framework to fix these problems. This is nearly identical to associations, with a few differences:
- I put edge metadata in a separate table and don't load it by default, to keep edge rows small and allow large metadata if necessary. The on-edge metadata seemed to get abused a lot at Facebook.
- I put a 'seq' column on the edges to ensure they have an explicit, stable ordering within a source and type.
This isn't actually used anywhere yet, but my first target is attaching commits to tasks for T904.
Test Plan: Made a mock page that used Editor and Query. Verified adding and removing edges, overwriting edges, writing and loading edge data, sequence number generation.
