Make line<->pixel_y conversion macros aware of native menu/tool bars.

They are placed above the internal border.  This supersedes special
treatment of native tool bars in the display code.

This fixes wrong display position of native menu bars and bogus mouse
highlighting of native tool bars, both of which can be found when
internal border width is large.  Also it fixes wrong flashed part on
visible bell with native menu bars.

* frame.h (FRAME_TOP_MARGIN_HEIGHT): New macro.
(FRAME_LINE_TO_PIXEL_Y, FRAME_PIXEL_Y_TO_LINE): Take account of pseudo
windows above internal border.

* window.h (WINDOW_MENU_BAR_P, WINDOW_TOOL_BAR_P): New macros.
(WINDOW_TOP_EDGE_Y, WINDOW_BOTTOM_EDGE_Y): Take account of pseudo
windows above internal border.

* xdisp.c (get_glyph_string_clip_rects, init_glyph_string): Don't treat
tool bar windows specially.

* xfns.c (x_set_tool_bar_lines): Take account of menu bar height.

* xterm.c (x_after_update_window_line): Don't treat tool bar windows
specially.
(XTflash): Take account of menu bar height.

* w32term.c (x_after_update_window_line): Don't treat tool bar windows
specially.
