unix: add SetsockoptTCPRepairOpt on Linux There is currently no function to allow for setting repair options for sockets in repair mode. There are 4 options catered for in the linux implementation. TCPOPT_WINDOW TCPOPT_MAXSEG TCPOPT_SACK_PERMITTED TCPOPT_TIMESTAMP Details of the patch to the kernel and the thinking behind it is here https://lwn.net/Articles/495304 Work done in this commit Included the tcp options type and length for inclusion in the Docker build Added TCPOPT to the regular expression in mkerrors.sh. There was only TCP_ previously Add the new function to syscall_unix.go I have tested locally and verified each option with ss -i I am not sure whether to commit tests because I don't know if socket creation is possible on the test runs in the offical pipeline. I did check for existing tests but didn't see any that created sockets, only one that validated a string option.
