Split network macro conditions

On Windows, interrupting a socket with shutdown() does not wake up
accept() or read() calls, the socket must be closed.

Introduce a new macro constant SC_SOCKET_CLOSE_ON_INTERRUPT, distinct of
_WIN32, because Windows will not be the only platform exhibiting this
behavior.
