[PATCH 3/9] remote-curl: let servers override http 404 advice

When we get an http 404 trying to get the initial list of refs from the server, we try to be helpful and remind the user that update-server-info may need to be run. This looks like:

  $ git clone https://github.com/non/existent
  Cloning into 'existent'...
  fatal: https://github.com/non/existent/info/refs?service=git-upload-pack not found: did you run git update-server-info on the server?

Suggesting update-server-info may be a good suggestion for users who are in control of the server repo and who are planning to set up dumb http. But for users of smart http, and especially users who are not in control of the server repo, the advice is useless and confusing.

The previous patch taught remote-curl to show custom advice from the server when it is available. When we have shown messages from the server, we can also drop our custom advice; what the server has to say is likely to be more accurate and helpful.

We not only drop the mention of update-server-info, but also show only the main repo URL, not the full "info/refs" and service parameter. These elements may be useful for debugging a broken server configuration, but again, anything the server has provided is likely to be more useful (and one can still use GIT_CURL_VERBOSE to get much more complete debugging information).
