Change more TUI functions to take a tui_source_window_base

Several more TUI functions should only be called with a source or
disassembly window.  This patch changes these functions so that this
can be caught at compile time.

	* tui/tui-winsource.h (tui_set_exec_info_content)

	(tui_clear_exec_info_content, tui_update_exec_info): Change
	argument to tui_source_window_base.
	* tui/tui-winsource.c (tui_set_exec_info_content)
	(tui_show_exec_info_content, tui_erase_exec_info_content)
	(tui_clear_exec_info_content, tui_update_exec_info): Change
	argument to tui_source_window_base.
