The old code implicitly set any sockets into non-blocking mode, and since there is no way to probe a socket to determine its blocking status using the win32 API, this was a real pain in the ass. The New implementation will hand off any sockets to winsock and use the WaitForObject API in win32 to probe other types of handle.
Since msvc sucks, I had to rename ext/standard/streams.c to ext/standed/streamsfuncs.c
…streams.c Move win32 select implementation into win32/. Will update win32 build in a moment.
