Fix corruption with multiple emacsclient -t instances.

This bug was introduced by my 2013-08-26 patch, which incorrectly
assumed that the terminfo implementation doesn't use termcap buffers.
* term.c (init_tty) [TERMINFO]: Remove optimization, as
these buffers apparently are used after all.
* termchar.h (TERMCAP_BUFFER_SIZE) [TERMINFO]: Define here too.
(struct tty_display_info): Define members termcap_term_buffer and
termcap_strings_buffer even if TERMINFO.

Ifdef away frame tool bar code when it is not really used.

and minimize_tool_bar_window_p under the above.
(fset_current_tool_bar_string, fset_desired_tool_bar_string)
(fset_tool_bar_window): Likewise.
* dispnew.c (clear_current_matrices, clear_desired_matrices)

* window.h (WINDOW_TOOL_BAR_P): Define to zero when frame tool bar
code is not really used.
* xdisp.c (build_desired_tool_bar_string, display_tool_bar_line)
(tool_bar_lines_needed, MAX_FRAME_TOOL_BAR_HEIGHT, tool_bar_item_info)
(get_tool_bar_item, handle_tool_bar_click, note_tool_bar_highlight)
[!USE_GTK && !HAVE_NS]: Define as such.
(Ftool_bar_lines_needed, redisplay_tool_bar, show_mouse_face)
(note_mouse_highlight, expose_frame):
* xfns.c (x_set_tool_bar_lines):
* xterm.c (handle_one_xevent): Adjust users.

Auto-commit of loaddefs files.
* xdisp.c (Ftool_bar_lines_needed): Declare as 'const' if ifdeffed out,

New member last_seen_part, going to replace...
* xterm.c [USE_TOOLKIT_SCROLL_BARS]: ...global last_scroll_bar_part.
(xt_action_hook) [USE_LUCID]: Adjust user.
(xm_scroll_callback, xg_scroll_callback): Do not bloat with
Lucid-specific scroll bar support.
(xaw_jump_callback, xaw_scroll_callback): Prefer enum scroll_par_part
to int and adjust to use last_seen_part member.
(x_set_toolkit_scroll_bar_thumb) [USE_LUCID]: Adjust user.
(x_scroll_bar_create) [USE_TOOLKIT_SCROLL_BARS && USE_LUCID]:
Initialize last_seen_part.
