This commit adds support for TCP Fast Open, without cookie management. To add support for this, I looked at the FreeBSD codebase and brought in some code from FreeBSD 12.0 that implements TCP Fast Open --- the version of FreeBSD that TCPlp is based on did not fully support TCP Fast Open. Normally, a part of TFO is cookie management --- the server generates a cookie and includes it in the initial handshake, and client is expected to present this cookie on future handshakes. This part is not yet implemented, and I changed the logic from FreeBSD to allow data to be exchanged in the TFO handshake even if the client does not present a cookie. If we implement this functionality for TFO later, it is probably worth departing from FreeBSD's data structures and policies for maintaining cookie state in favor of something that is simpler and more memory-efficient.
