	* tui.c (tui_show_source): Don't access current_source_symtab, use
	accessor function instead.  Include source.h and symtab.h
	* tuiDisassem.c (tuiShowDisassemAndUpdateSource,
	tuiVerticalDisassemScroll): Use accessor functions for current
	source line and symtab.  Include source.h.
	* tuiLayout.c (_extractDisplayStartAddr): Use accessor functions
	for current source line and symtab.  Include source.h.
	* tuiWin.c (_makeVisibleWithNewHeight): Ditto.
