lgtm with on fix below.

I didn't realize some of the issues were at this level. Is linkcheck happy with
these fixes?

Many of these are not "fixes" in that they weren't broken.

But I think it is nicer to use relative URLs for everything at
developer.chrome.com -- it will keep correct scheme, for example.

Done.

Oh, and I ran it through linkcheck and it was fine. There are other broken
links, but they should be fixed in another CL, I think.
