Summary:
Ref T2787. Carts need a status so we can tell if they've been purchased. Also kind of get WePay working as a one-time provider, and let charges not have a methodPHID (they won't for one-time providers).
All the status stuff is still super crazy rough and you can do things like start a checkout, add a bunch of stuff to your cart, complete the checkout, and have Phabricator think you paid for all the stuff you added. But this is fine for now since you can't actually edit carts, and also none of this is at all usable anyway. I'll refine some of the workflows in future diffs, for now I'm just getting things hooked up and technically working.
Test Plan:
- Purcahsed a cart and got a sort of status/done screen instead of a "your money is gone" exception.
- Went through the WePay flow and got a successful test checkout.

Roughly, the idea here is that applications create "purchases" (like "1 large t-shirt") and add them to "carts" (a user can have a lot of different carts at the same time), then hand things off to Phortune to deal with actualy charging a card. Roughly this works like Paypal or other similar systems do, except Phortune is the thing the user gets handed off to.

Instead:
- Let the edit policy be changed.
- Default the edit policy to "all users", similar to other applications.

- Migrate existing edit policies to be consistent with the old policy (just the author).
This stops short of adding a separate "owner" and letting that be changed, since Pholio doesn't really have any review/approve type features (at least, so far). We can look at doing this if we get more feedback about it, or if we make owners more meaningful (e.g., add more "review-like" process to mocks).

Ref T4045. Ref T5179. Hunk storage has two major issues:
- It's utf8, but actual diffs are binary.
- It's huge and can't be compressed or archived.
This introduces a second datastore which solves these problems: by recording hunk encoding, supporting compression, and supporting alternate storage. There's no actual compression or storage support yet, but there's space in the table for them.
Since nothing actually uses hunk IDs, it's fine to have these tables exist at the same time and use the same IDs. We can migrate data between the tables gradually without requiring downtime or disrupting installs.
Test Plan:
- There are no writes to the new table yet.
- The only effect this has is making us issue one extra query when looking for hunks.

Ref T4398. We have several auth-related systems which require (or are improved by) the ability to hand out one-time codes which expire after a short period of time.
In particular, these are:
- SMS multi-factor: we need to be able to hand out one-time codes for this in order to prove the user has the phone.
- Password reset emails: we use a time-based rotating token right now, but we could improve this with a one-time token, so once you reset your password the link is dead.
- TOTP auth: we don't need to verify/invalidate keys, but can improve security by doing so.
This adds a generic one-time code storage table, and strengthens the TOTP enrollment process by using it. Specifically, you can no longer edit the enrollment form (the one with a QR code) to force your own key as the TOTP key: only keys Phabricator generated are accepted. This has no practical security impact, but generally helps raise the barrier potential attackers face.
Followup changes will use this for reset emails, then implement SMS multi-factor.
Test Plan:
- Enrolled in TOTP multi-factor auth.
- Submitted an error in the form, saw the same key presented.
- Edited the form with web tools to provide a different key, saw it reject and the server generate an alternate.
- Change the expiration to 5 seconds instead of 1 hour, submitted the form over and over again, saw it cycle the key after 5 seconds.

For new commits, it is populated when commits are discovered.
For older commits, there's a `bin/repository parents` script to rebuild the data.
Right now, there's no UI suggestion that you should run the script. I haven't come up with a super clean way to do this, and this table will only improve performance for now, so it's not important that we get everyone to run the script right away. I'm just leaving it for the moment, and we can figure out how to tell admins to run it later.
The ultimate goal is to solve T2683, but solving T4455 gets us some stuff anyway (for example, we can serve `diffusion.commitparentsquery` faster out of this cache).
