(struct kboard): Renamed from struct KBOARD.
Move flag fields to the end, and make them chars.
Delete the `unused' field.
(KBOARD, etc): Moved from lisp.h.
* alloc.c, frame.c, frame.h, indent.c, keyboard.c, keyboard.h,
lisp.h, term.c, termhooks.h, window.c, window.h, xdisp.c, xfns.c,
xterm.c, xterm.h: Terminology changed.
Don't generate switch-frame events by checking Vlast_event_frame;
use a separate variable for that bookkeeping. In order to
generate them properly, we may need to fiddle with it.
* keyboard.c (internal_last_event_frame): New variable.
(command_loop_1): Check internal_last_event_frame, not
Vlast_event_frame.
(read_char, kbd_buffer_store_event): Set both Vlast_event_frame and
internal_last_event_frame.
(kbd_buffer_get_event): Check internal_last_event_frame to decide
whether to generate a switch-frame event. Set Vlast_event_frame
after each event.
(init_keyboard): Initialize both Vlast_event_frame and
internal_last_event_frame.
* keyboard.h (internal_last_event_frame): Add extern declaration
for this.
* frame.c (Vlast_event_frame): Remove external declaration for
this.
(Fselect_frame): Set internal_last_event_frame to Qnil to force a
switch-frame event, not Vlast_event_frame; the latter is supposed
to convey information to the user.
Qabove_handle, Qhandle, Qbelow_handle): New symbols.
(make_lispy_event): New code to build scrollbar clicks.
(make_lispy_movement): New code to handle scrollbar movement.
(head_table): Include Qscrollbar_movement in the event heads.
(syms_of_keyboard): Init and staticpro Qvertical_scrollbar,
Qabove_handle, Qhandle, and Qbelow_handle.
* keyboard.h (Qscrollbar_movement): Declare this along with the
other event types.
* lisp.h (Qvertical_scrollbar): Declare this.
* window.c (window_from_scrollbar): New function.
* xterm.h (struct x_display): Delete v_scrollbar, v_thumbup,
v_thumbdown, v_slider, h_scrollbar, h_thumbup,
h_thumbdown, h_slider, v_scrollbar_width, h_scrollbar_height
fields.
* keyboard.c (Qvscrollbar_part, Qvslider_part, Qvthumbup_part,
Qvthumbdown_part, Qhscrollbar_part, Qhslider_part, Qhthumbup_part,
Qhthumbdown_part, Qscrollbar_click): Deleted; part of an obsolete
interface.
(head_table): Removed from here as well.
(syms_of_keyboard): And here.
* keyboard.h: And here.
(POSN_SCROLLBAR_BUTTON): Removed.
* xscrollbar.h: File removed - no longer necessary.
* xfns.c: Don't #include it any more.
(Qhorizontal_scroll_bar, Qvertical_scroll_bar): Deleted.

adjust_scrollbars, x_resize_scrollbars): Deleted.
* xterm.c (construct_mouse_click): This doesn't need to take care of
scrollbar clicks anymore.
(XTread_socket): Remove old code to support scrollbars. Call new
functions instead for events which occur in scrollbar windows.
(XTupdate_end): Remove call to adjust_scrollbars; the main
redisplay code takes care of that now.
(enum window_type): Deleted.
* ymakefile: Note that xfns.o no longer depends on xscrollbar.h.
are not 5 elements long.
(EVENT_HEAD): Work correctly on all sorts of events, not just
events with parameters.
(EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON,
EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful
anymore; this information may appear twice in an event. These
are replaced by the POSN_ accessors, which are meant to be
composed with the EVENT_START and EVENT_END accessors.
(EVENT_START, EVENT_END): Two new accessors, to get at the
starting and ending position of an event.
(POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON,
POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher
diasassemble the values returned by EVENT_START and EVENT_END.
