xXPBSXxandClaude Sonnet 5.5 0bb7b02e9f fix(libkernel): answer a bound IPv4 datagram send to port 0 without the host
Linux's udp_sendmsg refuses port 0 with EINVAL, so a send that FreeBSD
accepts (the socket is bound to a specific address and port and the
destination is not INADDR_ANY or INADDR_BROADCAST) failed there. Nothing can
receive on port 0, so the call now returns the length itself on every host.
