[PATCH v4 20/40] bsd-user: Add socket system call dispatch

Wire up socket-related system calls in the FreeBSD syscall dispatcher:
accept, accept4, bind, bindat, connect, connectat, getpeername,
getsockname, getsockopt, setsockopt, listen, recvfrom, recvmsg,
sendmsg, sendto, socket, socketpair, shutdown, and setfib.
