Modified files:
	winsup/cygwin  : ChangeLog fhandler.cc fhandler.h 

Log message:
	* fhandler.cc (fhandler_base_overlapped::wait_overlapped): Remove
	special treatment for ERROR_NO_SYSTEM_RESOURCES.  Cancel I/O and reset
	the overlapped handle on error.
	(fhandler_base_overlapped::write_overlapped): Limit writes to
	max_atomic_write bytes in blocking case.  Incorporate code from
	now-defunct write_overlapped_fallback.  Fix serious oversight where ptr
	was not advanced as buffer was written.
	(fhandler_base_overlapped::write_overlapped_fallback): Eliminate.
	* fhandler.h (fhandler_base_overlapped::write_overlapped_fallback):
	Ditto for declaration.
	(DEFAULT_PIPEBUFSIZE): Lower size to slightly less than documented
	worst-case atomic write size.
	(fhandler_overlapped::wait_return): Remove unused element.
