Fixed X support, preliminary support for X-tty combo sessions.

lib-src/emacsclient.c (copy_from_to, pty_conversation): Re-added SIGIO
hack.  (Sigh.)

lisp/frame.el (make-frame-on-tty): Use make-terminal-frame, not
make-frame.

src/dispnew.c (line_hash_code, line_draw_cost): Updated to use
the new display_method parameters.
(Fredraw_frame): fflush the tty only if f is a termcap frame.
(direct_output_for_insert): Updated to use the new display_method
parameters. fflush the tty only if f is a termcap frame.
(direct_output_forward_char, update_frame_1, scrolling): Ditto.
(update_frame_line, Fding, bitch_at_user): Ditto.
(Fsend_string_to_terminal): Fail if current frame is not on a tty.
(init_display): Frame size change is safe here.


src/frame.c (Vterminal_frame): Restored previously deleted variable.
(syms_of_frame): Initialize it.
(make_terminal_frame): Copy the frame's display_method from tty_display_info.
(Fmake_terminal_frame): Enable simultaneous X and tty frames (buggy).
(Fredirect_frame_focus): Don't call frame_rehighlight_hook if frame
is on a termcap device.

src/frame.h (struct frame): Renamed display to display_method.
(Vterminal_frame): Re-added declaration.

src/keyboard.c (flow_control): Moved to struct tty_display_info.
(read_avail_input): Check ttys even if there is a read_socket_hook.
(Fset_input_mode): Call reset_sys_modes/init_sys_modes and set
flow_control or meta_key only when the frame is a termcap frame.
(Fcurrent_input_mode): Handle flow_control and meta_key right on
non-termcap frames.

src/scroll.c (calculate_scrolling, calculate_direct_scrolling): Update
to use the new display_method parameters.
(scrolling_1, scroll_cost): Ditto.

src/sysdep.c (init_sys_modes, reset_sys_modes): Always set the
terminal parameters if tty_out->input is not stdin.  Updated to the
new location of flow_control.
(hft_init): Moved HFT init code to term_init, as it needs the frame.

src/term.c (tty_display_method_template): New variable.
(update_begin): Added rif hack.
(set_terminal_window, ins_del_lines, term_init): Updated to use the
new display_method parameters.
(insert_glyphs, ins_del_lines): Only call insert_glyphs_hook if the
current frame is not on a tty.
(calculate_costs): Don't calculate costs if not on a tty.
(term_dummy_init): Fixed tty->output initialization. Preallocate Wcm
and display_method.
(term_init): Allocate & initialize display_method.  Blindly fixed
WINDOWSNT-specific parts.  Added HFT-specific initialization
exception from hft_init.
(delete_tty): Only delete termcap frames.  Free() the display_method.

src/termchar.h (struct tty_display_info): Moved high-level terminal
characteristics to struct display_method.  Added flow_control and
display_method members.

src/termhooks.h (struct display_method): New struct (renamed from
struct device).  Added accessor macros.

src/window.c (init_window_once): Initialize Vterminal_frame.

src/xdisp.c (init_iterator, expose_frame): Added rif hack.
(try_window_id): Updated to use the new display_method parameters.

src/xfaces.c (realize_basic_faces): Don't call
x_update_menu_appearance if the frame is a tty frame.

src/xfns.c (Fx_create_frame): Added rif hack.  Initialize
display_method.
(x_create_tip_frame): Initialize display_method.

src/xterm.c (x_display_method): New variable.
(x_flush, x_frame_of_widget, XTmouse_position): Ignore non-X frames.
(x_window_to_scroll_bar, x_window_to_menu_bar): Ditto.
(xim_destroy_callback, xim_instantiate_callback): Ditto.
(frame_highlight, frame_unhighlight): Added rif hack.
(x_initialize): Don't initialize rif.  Do initialize x_display_method.

src/xterm.h (x_display_method): New declaration.
