    Speed up GDB's TUI output

    In the TUI mode, we call wrefresh after outputting every single
    character.  This results in the I/O becoming very slow.  Fix this by
    delaying refreshing the console window until an explicit flush of
    gdb_stdout is requested, or a write to any other (unbuffered) file is
    done.
