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:
Ref T3720. Ref T4310. Currently, we limit the maximum number of concurrent sessions of each type. This is primarily because sessions predate garbage collection and we had no way to prevent the session table from growing fairly quickly and without bound unless we did this.
Now that we have GC (and it's modular!) we can just expire unused sessions after a while and throw them away:
- Add a `sessionExpires` column to the table, with a key.
- Add a GC for old sessions.
- When we establish a session, set `sessionExpires` to the current time plus the session TTL.
- When a user uses a session and has used up more than 20% of the time on it, extend the session.
In addition to this, we could also rotate sessions, but I think that provides very little value. If we do want to implement it, we should hold it until after T3720 / T4310.
Test Plan:
- Ran schema changes.
- Looked at database.
- Tested GC:
- Started GC.
- Set expires on one row to the past.
- Restarted GC.
- Verified GC nuked the session.
- Logged in.
- Logged out.
- Ran Conduit method.
- Tested refresh:
- Set threshold to 0.0001% instead of 20%.
- Loaded page.
- Saw a session extension ever few page loads.

Summary:
Ref T4310. Ref T3720. Two major things are going on here:
- I'm making this table work more like a standard table, which, e.g., makes `delete()` simpler to implement.
- Currently, the primary key is `(userPHID, type)`. I want to get rid of this, issue unlimited sessions, and GC old sessions. This means we can't have a unique key on `(userPHID, type)` anymore. This removes it as the primary key and adds it as a normal key instead. There's no functional change -- the code to generate sessions guarantees that it will never write duplicate rows or write additional rows -- but allows us to drop the `-1`, `-2` qualifiers in the future.
- Also of note, our task is made far simpler here because MySQL will automatically assign values to new `AUTO_INCREMENT` columns, so we don't have to migrate to get real IDs.
Test Plan: Ran migrations, verified table looked sane. Logged out, logged in.

Summary: Ref T4310. Ref T3720. Session operations are currently part of PhabricatorUser. This is more tightly coupled than needbe, and makes it difficult to establish login sessions for non-users. Move all the session management code to a `SessionEngine`.
Test Plan:
- Viewed sessions.
- Regenerated Conduit certificate.
- Verified Conduit sessions were destroyed.

Summary:
Ref T603. Adds clarifying text which expands on policies and explains exceptions and rules. The goal is to provide an easy way for users to learn about special policy rules, like "task owners can always see a task".
This presentation might be a little aggressive. That's probably OK as we introduce policies, but something a little more tempered might be better down the road.
Test Plan: See screenshot.

We can get this out of PHIDType reasonably in all cases and simplify implementation here.
None of these translate correctly anyway so they're basically debugging/development strings.

Summary:
Ref T1536. Currently, we have about 40 auth-related configuration options. This is already roughly 20% of our config, and we want to add more providers. Additionally, we want to turn some of these auth options into multi-auth options (e.g., allow multiple Phabricator OAuth installs, or, theoretically multiple LDAP servers).
I'm going to move this into a separate "Auth" tool with a minimal CLI (`bin/auth`) interface and a more full web interface. Roughly:
- Administrators will use the app to manage authentication providers.
- The `bin/auth` CLI will provide a safety hatch if you lock yourself out by disabling all usable providers somehow.
- We'll migrate existing configuration into the app and remove it.
General goals:
- Make it much easier to configure authentication by providing an interface for it.
- Make it easier to configure everything else by reducing the total number of available options.
Test Plan: Ran storage upgrade.
