unified msw and tty event loops

This unifies the mswindows and tty event loops under cygwin. gnuclient -nw does the right thing if you have a mswindows frame up. I get messages in both echo areas currently - I don't know whether this is supposed to happen. GUEL (Grand Unified Event Loop) is a larger leap away. andy 1999-02-16 Andy Piper <andy(a)xemacs.org&gt; * event-tty.c (tty_find_console_from_fd): rename from find_console_from_fd. (emacs_tty_next_event): use tty_find_console_from_fd. * event-msw.c (emacs_mswindows_select_console): ignore selection of mswindows consoles otherwise do the unixoid thig. (emacs_mswindows_unselect_console): ditto. * console-tty.h: declare tty_find_console_from_fd(); * event-msw.c (mswindows_need_event): always use select if we have a msg based select. If tty events are pending, process them.
