This patch first adds TFO support in mptcp_connect.c. This can be enabled via a new option: -o MPTFO. Once enabled, the TCP_FASTOPEN socket option is enabled for the server side and a sendto() with MSG_FASTOPEN is used instead of a connect() for the client side. Note that the first SYN has a limit of bytes it can carry. In other words, it is allowed to send less data than the provided one. We then need to track more status info to properly allow the next sendmsg() starting from the next part of the data to send the rest. Also in TFO scenarios, we need to completely spool the partially xmitted buffer -- and account for that -- before starting sendfile/mmap xmit, otherwise the relevant tests will fail.
