Reorganize header file inclusion throughout so that cygerrno.h comes first. 

* fhandler.h (select_record::thread_errno): Save any encountered errno here.
(select_record::set_select_errno): New function.
(select_record::saw_error): New function.
(select_record::select_record): Initialize thread_errno to zero.
* select.cc (set_handle_or_return_if_not_open): Set thread_errno on failure.
(select_stuff::wait): Record errno for later resurrection in calling thread.
(peek_serial): Ditto.
