Move shared HTTP request functionality out of http-fetch and http-push, and replace the two fwrite_buffer/fwrite_buffer_dynamic functions with one fwrite_buffer function that does dynamic buffering. Use slot callbacks to process responses to fetch object transfer requests and push transfer requests, and put all of http-push into an #ifdef check for curl multi support.
