Fixes#20067
Our password autocomplete hints were “off” but that does not prevent current
browsers from trying to autocomplete them anyway, so use `current-password` and
`new-password` so they don't put a newly-generated password in a password
confirmation prompt, or the old password for a password renewal prompt.
* Remove support for OAUTH_REDIRECT_AT_SIGN_IN
Fixes#15959
Introduced in #6540, OAUTH_REDIRECT_AT_SIGN_IN allowed skipping the log-in form
to instead redirect to the external OmniAuth login provider.
However, it did not prevent the log-in form on /about introduced by #10232 from
appearing, and completely broke with the introduction of #15228.
As I restoring that previous log-in flow without introducing a security
vulnerability may require extensive care and knowledge of how OmniAuth works,
this commit removes support for OAUTH_REDIRECT_AT_SIGN_IN instead for the time
being.
* Add OMNIAUTH_ONLY environment variable to enforce external log-in only
* Disable user registration when OMNIAUTH_ONLY is set to true
* Replace log-in links When OMNIAUTH_ONLY is set with exactly one OmniAuth provider
* Verify link ownership with rel="me"
* Add explanation about verification to UI
* Perform link verifications
* Add click-to-copy widget for verification HTML
* Redesign edit profile page
* Redesign forms
* Improve responsive design of settings pages
* Restore landing page sign-up form
* Fix typo
* Support <link> tags, add spec
* Fix links not being verified on first discovery and passive updates
