[w3m-dev 03456] tiling of tab

* display.c (displayBuffer): use LastTab->y
	(redrawNLine): fix column calculation
* fm.h (TabBuffer): add x1, x2, y
* main.c (calcTabPos): added
	(main): calcTabPos()
	(mouse_scroll_line): rewrite
	(process_mouse): use LastTab->y
	(_newT): calcTabPos()
	(calcTabPos): added
	(deleteTab): calcTabPos()
	(moveTab): calcTabPos()
