Summary:
Fixes T3471. Specific issues:
- Add the ability to set a temporary cookie (expires when the browser closes).
- We overwrote 'phcid' on every page load. This creates some issues with browser extensions. Instead, only write it if isn't set. To counterbalance this, make it temporary.
- Make the 'next_uri' cookie temporary.
- Make the 'phreg' cookie temporary.
- Fix an issue where deleted cookies would persist after 302 (?) in some cases (this is/was 100% for me locally).
Test Plan:
- Closed my browser, reopned it, verified temporary cookies were gone.
- Logged in, authed, linked, logged out.

Summary:
Fixes T3793. There's a lot of history here, see D4012, T2102. Basically, the problem is that things used to work like this:
- User is logged out and accesses `/xyz/`. After they login, we'd like to send them back to `/xyz/`, so we set a `next_uri` cookie.
- User's browser has a bunch of extensions and now makes a ton of requests for stuff that doesn't exist, like `humans.txt` and `apple-touch-icon.png`. We can't distinguish between these requests and normal requests in a general way, so we write `next_uri` cookies, overwriting the user's intent (`/xyz/`).
To fix this, we made the 404 page not set `next_uri`, in D4012. So if the browser requests `humans.txt`, we 404 with no cookie, and the `/xyz/` cookie is preserved. However, this is bad because an attacker can determine if objects exist and applications are installed, by visiting, e.g., `/T123` and seeing if they get a 404 page (resource really does not exist) or a login page (resource exists). We'd rather not leak this information.
The comment in the body text describes this in more detail.
This diff sort of tries to do the right thing most of the time: we write the cookie only if we haven't written it in the last 2 minutes. Generally, this should mean that the original request to `/xyz/` writes it, all the `humans.txt` requests don't write it, and things work like users expect. This may occasionally do the wrong thing, but it should be very rare, and we stop leaking information about applications and objects.
Test Plan: Logged out, clicked around / logged in, used Charles to verify that cookies were set in the expected way.

Summary:
Ref T4339. Ref T4310. Currently, sessions look like `"afad85d675fda87a4fadd54"`, and are only issued for logged-in users. To support logged-out CSRF and (eventually) external user sessions, I made two small changes:
- First, sessions now have a "kind", which is indicated by a prefix, like `"A/ab987asdcas7dca"`. This mostly allows us to issue session queries more efficiently: we don't have to issue a query at all for anonymous sessions, and can join the correct table for user and external sessions and save a query. Generally, this gives us more debugging information and more opportunity to recover from issues in a user-friendly way, as with the "invalid session" error in this diff.
- Secondly, if you load a page and don't have a session, we give you an anonymous session. This is just a secret with no special significance.
This does not implement CSRF yet, but gives us a client secret we can use to implement it.
Test Plan:
- Logged in.
- Logged out.
- Browsed around.
- Logged in again.
- Went through link/register.

Summary: We currently have a lot of calls to `addCrumb(id(new PhabricatorCrumbView())->...)` which can be expressed much more simply with a convenience method. Nearly all crumbs are only textual.
Test Plan:
- This was mostly automated, then I cleaned up a few unusual sites manually.
- Bunch of grep / randomly clicking around.

Summary:
Ref T1536. Currently, when you install Phabricator you're dumped on the login screen and have to consult the documentation to learn about `bin/accountadmin`.
Instead, detect that an install is running first-time setup:
- It has no configured providers; and
- it has no user accounts.
We can safely deduce that such an install isn't configured yet, and let the user create an admin account from the web UI.
After they login, we raise a setup issue and lead them to configure authentication.
(This could probably use some UI and copy tweaks.)

Summary:
Ref T1536. This is extremely reachable and changes the login code to the new stuff.
Notes:
- I've hard-disabled password registration since I want installs to explicitly flip it on via config if they want it. New installs will get it by default in the future, but old installs shouldn't have their auth options change.
- Google doesn't let us change the redirect URI, so keep the old one working.
- We need to keep a bit of LDAP around for now for LDAP import.
- **Facebook:** This causes substantive changes in what login code is executed.
Test Plan:
- Logged in / logged out / registered, hit new flows.
- Logged in with google.
- Verified no password registration by default.

Summary:
Ref T1536. Facebook currently does a check which should be on-login in registration hooks, and this is generally a reasonable hook to provide.
The "will login" event allows listeners to reject or modify a login, or just log it or whatever.
NOTE: This doesn't cover non-web logins right now -- notably Conduit. That's presumably fine.
(This can't land for a while, it depends on about 10 uncommitted revisions.)

Summary:
Ref T1445. Ref T1536. Although we have separate CSRF protection and have never been vulnerable to OAuth hijacking, properly implementing the "state" parameter provides a little more certainty.
Before OAuth, we set a random value on the client, and pass its hash as the "state" parameter. Upon return, validate that (a) the user has a nonempty "phcid" cookie and (b) the OAuth endpoint passed back the correct state (the hash of that cookie).
Test Plan: Logged in with all OAuth providers, which all apparently support `state`.

Summary:
Ref T1536. Code is intentionally made unreachable (see PhabricatorAuthProviderOAuthFacebook->isEnabled()).
This adds:
- A provider-driven "start" screen (this has the list of ways you can login/register).
- Registration actually works.
- Facebook OAuth works.
@chad, do you have any design ideas on the start screen? I think we poked at it before, but the big issue was that there were a limitless number of providers. Today, we have:
- Password
- LDAP
- Facebook
- GitHub
- Phabricator
- Disqus
- Google
We plan to add:
- Asana
- An arbitrary number of additional instances of Phabricator
Users want to add:
- OpenID
- Custom providers
And I'd like to have these at some point:
- Stripe
- WePay
- Amazon
- Bitbucket
So basically any UI for this has to accommodate 300 zillion auth options. I don't think we need to solve any UX problems here (realistically, installs enable 1-2 auth options and users don't actually face an overwhelming number of choices) but making the login forms less ugly would be nice. No combination of prebuilt elements seems to look very good for this use case.
Test Plan: Registered a new acount with Facebook.
