Log message:
	Christopher Faylor <me.cygwin2012@cgf.cx>
	* fhandler.h (wait_return): Add overlapped_nullread.
	* fhandler.cc (fhandler_base_overlapped::wait_overlapped): Detect zero-byte
	read as a special case.
	(fhandler_base_overlapped::raw_read): Keep looping when zero-byte read detected
	without EOF.
	(fhandler_base_overlapped::raw_write): Quiet gcc warning by adding
	overlapped_nullread to switch statement even though it will never actually be
	hit.
