    Remove the TUI annotation hack
    
    do_tui_putc has some code to remove annotations from gdb output.  This
    was added in 2001, see commit a198b876bbcb.
    
    However, I think this code is not needed.  It seems very unlikely to
    enable both annotations and the TUI, and in any case I think this is
    something that should not be supported.
    
    So, this patch removes this code.
