Originally, the patch was fixing a bunch of issues, but Peter beat me
to it with earlier commit "slirp: fork_exec(): create and connect
child socket before fork()".
Factor out socket pair creation, to simplify the fork_exec() code.
Use the name socketpair_with_oob() since the code is actually similar
to what socketpair() would do, except that it uses TCP sockets, for
SLIRP to be able to call send with MSG_OOB (since SO_OOBINLINE is set,
this could probably be faked instead on regular unix sockets though).
