Stream: do not split datagrams when limiting proxy rate. Previously, when using proxy_upload_rate and proxy_download_rate, the buffer size for reading from a socket could be reduced as a result of rate limiting. For connection-oriented protocols this behavior is normal since unread data will normally be read at the next iteration. But for datagram-oriented protocols this is not the case, and unread part of the datagram is lost. Now buffer size is not limited for datagrams. Rate limiting still works in this case by delaying the next reading event.
