Currently, functions that deal with objects on the remote repository have to allocate and do strcpys to generate the URL.
This patch saves them this trouble, by providing two functions, "append_remote_object_url" and "get_remote_object_url".
Both generate a URL, with either the object's 2-digit hex directory (eg. /objects/a1/), or the complete object location (eg. /objects/a1/b2).
However, they differ in that "append_remote_object_url" appends this URL to a strbuf, while "get_remote_object_url" wraps around the former and returns the URL directly in char*. Users usually would use "get_remote_object_url", but may find "append_remote_object_url" useful if they require further string operations on the URL.
PS. In "start_fetch_loose", the variable "url" which is passed to "curl_easy_setopt" is removed, and in its place "request->url" is used. This is safe, since curl strdup's it.
