Auto merge of #23363 - Darkspirit:https, r=jdm

More https

* Disabled unused legacy TLS.
It will be disabled for Nightly 72 or 73 in 5-7 months and ride the [trains](https://wiki.mozilla.org/Release_Management/Calendar).
https://blog.mozilla.org/security/2018/10/15/removing-old-versions-of-tls/
* Updated MPL license in a few files.
It would be nice if a new version of https://pypi.org/project/servo_tidy/ could be released to update WebRender as well.
* Switched servo-deps.s3.amazonaws.com back to https.
This was recently regressed by 10585be25c334bd15710d1a6d93391a9acb6d543 and fc28073dfba05cb2d3fda624c135b2125c1b90af.
* Made https the default protocol for address bar on desktop.
Press Ctrl+L on the Glutin port and enter `example.com`:
Servo previously assumed you meant `http://example.com/`, now it is `https://example.com/`.
