* fhandler.cc (fhandler_base_overlapped::wait_overlapped): Use simplified arg
form of cygwait.

open.
(fhandler_pty_slave::read): Send SIGHUP when master is detected as closed.
(fhandler_pty_common::close): Close input_available_event in callers since
master may need to signal it first.

then close input_available_event.
(fhandler_pty_slave::close): Close input_available_event explicitly here.
