Hi!

This patch improves the TUI mode by creating a specific readline keymap
that can be installed to bind a single key to a gdb command.  The fast key
mode is entered when CTRL-X CTRL-O is entered.  Then, the keys are bound
as follows:

   c  continue
   d  down
   f  finish
   n  next
   r  run
   s  step
   u  up
   v  info locals
   w  where
   x  exit the fast key mode, go back to normal readline+gdb prompt

Hitting a single key will execute the gdb command.
Other keys temporarily switch the keymap to use the readline+gdb prompt
so that a full gdb command can be entered.  Once the command is entered (\n)
the fast key mode is restored.

I'll commit this patch in a few days unless there is some objection.
