remote-curl: supports git-upload-archive service

Add new service (git-upload-archive) support in remote-curl, so we can support remote archive over HTTP/HTTPS protocols. Differences between git-upload-archive and other services: 1. The git-archive program does not expect to see protocol version and capabilities when connecting to remote-helper, so do not send them in remote-curl for the git-upload-archive service. 2. We need to detect protocol version by calling discover_refs(). Fallback to use the git-upload-pack service (which, like git-upload-archive, is a read-only operation) to discover protocol version.
