[PATCH] Ctrl-D

Hi,

In response to the recent discussion of Ctrl-D behaviour on the GDB 
list, here is a patch which attempts to address the issues identified.

This example shows two presses of Crtl-D:

Old behaviour:

(gdb) <C-d>The program is running.  Exit anyway? (y or n) <C-d>bash$

New behaviour:

(gdb) <C-d>quit
The program is running.  Exit anyway? (y or n) <C-d>Y
bash$


In addition to these cosmetic changes, in have adjusted the code such 
that hook-quit will work, as will trace-commands:

(gdb) define hook-quit
Type commands for definition of "hook-quit".
End with a line saying just "end".
 >set confirm 0
 >end
(gdb) set trace-commands on
(gdb) <C-d>quit
+quit
++set confirm 0
bash$

	* event-top.c (command_handler): On EOF, print 'quit' and run quit
	command via execute_command such that hooks and trace work.
	* utils.c (defaulted_query): On EOF, print default answer and newline.
