[PATCH]: Provide TUI fast key action with specific readline keymap

[Stephane Carrez]

Hi!

I've committed this patch to improve the TUI as explained in
http://sources.redhat.com/ml/gdb-patches/2002-08/msg00840.html.

I changed a little bit the patch to simplify and use an enum to represent the
3 key-mode states (command, SingleKey, one-command then SingleKey).

To activate SingleKey, it is bound to C-X S.
To leave it, both C-X S and 'q' work.

Note: In http://sources.redhat.com/ml/gdb-patches/2002-08/msg00907.html
       I proposed to use C-X C-S to activate; but C-S is very bad as it's
       used to stop the terminal output...
