Improve threading and i/o routines
- On Windows connect() can now be interrupted by a signal; connect() w/ O_NONBLOCK will now raise EINPROGRESS; and connect() with SO_SNDTIMEO will raise ETIMEDOUT after the interval has elapsed. - We now get the AcceptEx(), ConnectEx(), and TransmitFile() functions from the WIN32 API the officially blessed way, using WSAIoctl(). - Do nothing on Windows when fsync() is called on a directory handle. This was raising EACCES earlier becaues GENERIC_WRITE is required on the handle. It's possible to FlushFileBuffers() a directory handle if it's opened with write access but MSDN doesn't document what it does. If you have any idea, please let us know! - Prefer manual reset event objects for read() and write() on Windows. - Do some code cleanup on our dlmalloc customizations. - Fix errno type error in Windows blocking routines. - Make the futex polyfill simpler and faster.
