Switch MessagePumpForIO to use completion ports on Windows.

Cleanup the separation between MessagePumpForUI and 
MessagePumpForIO, and convert the latter to use Completion
Ports instead of MsgWaitForMultipleobjects to sleep
when idle.

Remove all traces of Windows messages from MessagePumpForIO,
remove the transitional API of completion port notifications
and remove WatchObject API.

Modify all callers of RegisterIOHandler so that they are no
longer using RegisterIOContext, and also handle properly
the new semantics of completion ports (notifications even when
the IO completes immediately).

Add a new interface to allow proper cleanup of disk cache (to
replace code that was waiting for pending APCs from the destructor).

Add a way for the message pump to perform cleanup of abandoned IO.
