Create a content::UrlFetcher interface that lives in content/public/common and convert users to it. I have added a static create function, but will switch instantiations to use it in another change since this has grown a lot. Basically this change converts function names away from unix_hacker style, which they shouldn't have been using anyways since some are virtual, and made all of the other functions virtual.
