This change adds support for message mode pipes and uses them to support CloseWrite() to better match TCP and UNIX sockets. Message mode pipes support writing and (optionally) reading data in message-sized chunks. This is useful for us because when in this mode a zero-sized message can be read. We use this zero-sized message to signal that no more writes will arrive. This is not standard practice in Windows, but it is a reasonable compromise.
