Recent docs website shuffling during 1.6 caused majority of links in the API
types and fields to break. Since we do not have server-side 301 redirects, user
has to click an extra link and the #target segment in the URL will be lost.

I have manually gone through all of them to bring them up to date and add HTTPS
to those missing it.
