Hookified termcap devices, added bootstrap display device, plus many bugfixes.

lisp/frame.el (display-color-cells): Pass display parameter to tty-display-color-cells.

lisp/term/xterm.el (xterm-register-default-colors): Pass the selected-frame to display-color-cells.

src/dispextern.h (set_terminal_modes, reset_terminal_modes): Removed declarations.
(get_named_tty_display): New prototype.
(tty_clear_end_of_line, term_init): Updated to new prototype.
(initial_term_init): Renamed to init_initial_display.

src/dispnew.c (Fredraw_frame): ifdef-out DOS-specific code.  Add display parameter to set_terminal_modes call.
(update_frame): Don't flush the tty of there is no tty.
(init_display): Set up a termcap display on the controlling tty and
change the initial frame to use that.  Delete the initial display.

src/frame.c (Fframep): Return t for the initial frame.
(make_initial_frame): New function for creating the initial frame during bootstrap.  Use init_initial_display, not initial_term_init.
(make_terminal_frame): Removed special cases for creating the initial frame.

src/frame.h (enum output_method): New entry: output_initial for the bootstrap display.
(FRAME_INITIAL_P): New macro.
(make_initial_frame): New prototype.

src/keyboard.c (interrupt_signal): Exit Emacs on SIGINT from the (frameless) controlling tty, if possible.  Explain this in a comment.
(init_keyboard): Added comment about exiting on SIGINT.
(Fset_input_mode): A termcap frame is never the initial frame anymore.

src/sysdep.c (init_sys_modes): Update tty_set_terminal_modes call to the new prototype.
(reset_sys_modes): Comment out tty_clear_end_of_line call; it doesn't work anymore.  Update tty_reset_terminal_modes call.

src/termchar.h (struct tty_display_info): Added pointer to the display structure, for reset_sys_modes.

src/termhooks.h (struct display): Added display parameter to set_terminal_modes_hook and reset_terminal_modes_hook.

src/term.c (initial_display): New variable.
(tty_ring_bell, tty_update_end, tty_set_terminal_window, tty_cursor_to)
(tty_raw_cursor_to, tty_clear_to_end, tty_clear_frame, tty_clear_end_of_line)
(tty_write_glyphs, tty_insert_glyphs, tty_delete_glyphs, tty_ins_del_lines): New functions.
(ring_bell, update_end, set_terminal_window, cursor_to, raw_cursor_to)
(clear_to_end, clear_frame, clear_end_of_line, write_glyphs, insert_glyphs)
(delete_glyphs, ins_del_lines): Removed special casing of termcap displays.
(get_tty_display): New function.
(Ftty_display_color_p, Ftty_display_color_cells): Use it.
(get_named_tty_display): Removed static.
(tty_set_terminal_modes, tty_reset_terminal_modes): Changed to use a display parameter
instead of tty_display_info for hook compatibility.
(set_terminal_modes, reset_terminal_modes): Removed.
(initial_term_init): Renamed to init_initial_display.  Set up an
output_initial device, not a termcap display.
(delete_initial_display): New function.
(maybe_fatal): New function, for private use of term_init.
(term_init): New parameter for choosing between fatal and simple errors.
Removed incomprehensible special casing for the second initialization of the
controlling tty.  Use maybe_fatal for error handling.
Initialize termcap display hooks in the new device.
Initialize the display pointer in the tty_display_info structure.
(delete_tty): Replace order of reset_sys_modes and delete_display.

src/window.c (init_window_once): Call make_initial_frame instead of make_terminal_frame.
