Summary:
Ref T13222. Ref T13225. We store a digest of the session key in the session table (not the session key itself) so that users with access to this table can't easily steal sessions by just setting their cookies to values from the table.
Users with access to the database can //probably// do plenty of other bad stuff (e.g., T13134 mentions digesting Conduit tokens) but there's very little cost to storing digests instead of live tokens.
We currently digest session keys with HMAC-SHA1. This is fine, but HMAC-SHA256 is better. Upgrade:
- Always write new digests.
- We still match sessions with either digest.
- When we read a session with an old digest, upgrade it to a new digest.
In a few months we can throw away the old code. When we do, installs that skip upgrades for a long time may suffer a one-time logout, but I'll note this in the changelog.
We could avoid this by storing `hmac256(hmac1(key))` instead and re-hashing in a migration, but I think the cost of a one-time logout for some tiny subset of users is very low, and worth keeping things simpler in the long run.
Test Plan:
- Hit a page with an old session, got a session upgrade.
- Reviewed sessions in Settings.
- Reviewed user logs.
- Logged out.
- Logged in.
- Terminated other sessions individually.
- Terminated all other sessions.
- Spot checked session table for general sanity.

Summary: Ref T12509. This encourages code to move away from HMAC+SHA1 by making the method name more obviously undesirable.
Test Plan: `grep`, browsed around.

Summary: See D14025. In all cases where we compare hashes, use strict, constant-time comparisons.
Test Plan: Logged in, logged out, added TOTP, ran Conduit, terminated sessions, submitted forms, changed password. Tweaked CSRF token, got rejected.

Summary:
- Dialog pages currently have no titles or crumbs, and look shoddy. Add titles and crumbs.
- Dialog titles aren't always great for crumbs, add an optional "short title" for crumbs.
- `AphrontDialogResponse` is pure boilerplate. Allow controllers to just return a `DialogView` instead and get the same effect.
- Building dialogs requires a bit of boilerplate, and we generally construct them with no explicit `"action"`, which has some issues with T4593. Provide a convenience method to set the viewer and get a reasonable, explict submit URI.
Test Plan:
- Viewed dialog on its own.
- Viewed dialog as a dialog.

Summary:
This is partly a good feature, and partly should reduce false positives on HackerOne reporting things vaguely related to this.
Allow a user to terminate login sessions from the settings panel.
Test Plan:
- Terminated a session.
- Terminated all sessions.
- Tried to terminate all sessions again.
- Logged in with two browsers, terminated the other browser's session, reloaded, got kicked out.
