The code handling the fetching of packs in http-push.c and http-walker.c have been refactored into new methods and a new struct (http_pack_request) in http.c. They are not meant to be invoked elsewhere. The new methods in http.c are - new_http_pack_request - finish_http_pack_request - release_http_pack_request and the new struct is http_pack_request. Add a function, new_http_pack_request(), that deals with the details of coming up with the filename to store the retrieved packfile, resuming a previously aborted request, and making a new curl request. Update http-push.c::start_fetch_packed() and http-walker.c::fetch_pack() to use this. Add a function, finish_http_pack_request(), that deals with renaming the pack, advancing the pack list, and installing the pack. Update http-push.c::finish_request() and http-walker.c::fetch_pack to use this. Update release_request() in http-push.c and http-walker.c to invoke release_http_pack_request() to clean up pack request helper data. The local_stream member of the transfer_request struct in http-push.c has been removed, as the packfile pointer will be managed in the struct http_pack_request.
