Remove separate visibility flag
TUI windows keep track of their visibility in a boolean field. However, this is not needed, because a window is visible if and only if it has an underlying curses handle. So, we can remove this separate field. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_is_window_visible): Update. * tui/tui-wingeneral.c (tui_make_window) (tui_gen_win_info::make_visible, tui_refresh_all): Update. * tui/tui-win.c (window_name_completer, tui_refresh_all_win) (tui_set_focus_command, tui_all_windows_info, update_tab_width) (tui_set_win_height_command, parse_scrolling_args): Update. * tui/tui-source.c (tui_source_window::style_changed): Update. * tui/tui-regs.c (tui_show_registers) (tui_data_window::first_data_item_displayed) (tui_data_window::delete_data_content_windows) (tui_check_register_values, tui_reg_command): Update. * tui/tui-disasm.c (tui_show_disassem): Update. * tui/tui-data.h (struct tui_gen_win_info) <is_visible>: New method. <is_visible>: Remove field. * tui/tui-data.c (tui_next_win, tui_prev_win) (tui_delete_invisible_windows): Update.
