Summary:
- There are some recent reports of login issues, see T755 and T754. I'm not
really sure what's going on, but this is an attempt at getting some more
information.
- When we login a user by setting 'phusr' and 'phsid', send them to
/login/validate/ to validate that the cookies actually got set.
- Do email password resets in two steps: first, log the user in. Redirect them
through validate, then give them the option to reset their password.
- Don't CSRF logged-out users. It technically sort of works most of the time
right now, but is silly. If we need logged-out CSRF we should generate it in
some more reliable way.
Test Plan:
- Logged in with username/password.
- Logged in with OAuth.
- Logged in with email password reset.
- Sent bad values to /login/validate/, got appropriate errors.
- Reset password.
- Verified next_uri still works.
