This introduces a config setting remote.$remotename.pushurl which is used for pushes only. If absent remote.$remotename.url is used for pushes and fetches as before. This is useful, for example, in order to to do passwordless fetches (remote update) over git: but pushes over ssh.

This is a working prototype, but I'd like to rfc about the approach before
coding further. Do I need to do anything in http-push.c? I don't think so.
Things that would go in a full series:
* documentation (man pages, maybe manual)
* tests
* teach builtin-remote about pushurl
