3830b6enet: use CreateSocket for binds (Cory Fields)df3bcf8net: pass socket closing responsibility up to caller for outgoing connections (Cory Fields)9e3b2f5net: Move IsSelectableSocket check into socket creation (Cory Fields)1729c29net: split socket creation out of connection (Cory Fields) Pull request description: Requirement for #11227. We'll need to create sockets and perform the actual connect in separate steps, so break them up. #11227 adds an RAII wrapper around connection attempts, as a belt-and-suspenders in case a CloseSocket is missed.
