It's because we can switch on/off the TUI mode while gdb is running
(independently of -tui option).

CTRL-X CTRL-A is bound to tui_switch_mode() which enables TUI mode or
disable it (the effect is similar to using the gdb -tui option, or, not using that option).

The tui_enable() and tui_disable() do all the necessary stuff such as
enter/leave the curses mode, install/remove specific TUI gdb hooks.
The 'uiout' is also switched here so that we write on gdb_stdout
or in curses window.
