Separate frame-local, tty-dependent parameters from tty-local parameters.

src/termchar.h (struct tty_output): Redefined to contain frame-local
tty-dependent parameters.  (Currently there are no such parameters, so
it consists of the tty_display_info pointer.)
(struct tty_display_info): New structure, with reference_count.
(FRAME_TTY): Updated to reflect new termcap frame structure.

src/term.c: Update prototypes. Use tty_display_info instead of tty_output.

src/cm.c (current_tty, cmcheckmagic, cmcostinit, calccost, cmgoto, Wcm_clear)
(Wcm_init): Use tty_display_info instead of tty_output.

src/cm.h: Update prototypes.
src/dispextern.h: Ditto.

src/dispnew.c (window_change_signal, init_display, make_terminal_frame):
Use tty_display_info instead of tty_output.

src/frame.c (Fdelete_frame): Use tty_display_info instead of
tty_output.  Fix delete_tty check.
(make_terminal_frame): Allocate f->output_data.tty.  Increase
reference count of tty device.
(delete_frame): Free f->output_data.tty.  Use reference count to
decide if the tty should be closed.

src/frame.h (FRAME_FOREGROUND_PIXEL, FRAME_BACKGROUND_PIXEL): New,
unconditional definitions.
(struct device): New declaration (at the moment, it is defined as
empty in termhooks.h).
(struct frame): Added display, background_pixel, foreground_pixel member.

src/keyboard.c (read_avail_input): Use tty_display_info instead of tty_output.

src/lisp.h: Declare struct display.  Update prototypes.

src/sysdep.c: Update prototypes.
(discard_tty_input, init_all_sys_modes, init_sys_modes, reset_all_sys_modes)
(reset_sys_modes, hft_init, hft_reset): Use tty_display_info instead
of tty_output.
