hgweb: inline caching() and port to modern mechanisms We only had one consumer of this simple function. While it could be a generic function, let's not over abstract the code. As part of inlining, we port it off wsgirequest, fix some Python 3 issues, and set a response header on our new response object so it is ready once we start using it to send responses.
