Properly support socketpair and reading and writing non-blocking sockets
Summary:
Also handle invalid file descriptors correctly and switch away from `WSASendMsg` for the implementation of `sendmsg` due to limitations imposed by WinSock.
This also fixes up a few places that were explicitly referencing the global version of some socket functions, which was bypassing the socket portability layer.
