socket: add missing TCP socket options from Linux

[matttbe]

Feature or enhancement

socket modules already know most TCP socket options (TCP_NODELAY, TCP_MAXSEG, TCP_CORK, etc.) but not the recent ones.

Here is the complete list from the last Linux kernel version:

Pitch

I noticed TCP_FASTOPEN_CONNECT was missing. I wanted to use it to write some quick tests for the kernel (MPTCP development). I was going to add only this one but while at it, best to add all the missing ones.
