	gdb/testsuite/gdb.base: list.exp 

Log message:
	list.exp: Catch "set listsize" failures (and "set listsize -1/0"'s history).
	
	Before the changes starting at
	http://sourceware.org/ml/gdb-patches/2012-08/msg00020.html, the 'set
	listsize' command only accepted "0" as special value, meaning
	"unlimited".  The testsuite actually tried "set listsize -1" and
	expected that to mean unlimited too.
	
	If you tried testing list.exp at the time of that patch above,
	you'd get:
	
	(gdb) PASS: gdb.base/list.exp: list line 10 with listsize 100
	set listsize 0
	(gdb) PASS: gdb.base/list.exp: setting listsize to 0 #6
	show listsize
	Number of source lines gdb will list by default is unlimited.
	(gdb) PASS: gdb.base/list.exp: show listsize unlimited #6
	list 1
	1       #include "list0.h"
	2
	...
	42          /* Not used for anything */
	43      }
	(gdb) PASS: gdb.base/list.exp: listsize of 0 suppresses output
	set listsize -1
	integer 4294967295 out of range
	(gdb) PASS: gdb.base/list.exp: setting listsize to -1 #7
	show listsize
	Number of source lines gdb will list by default is unlimited.
	(gdb) PASS: gdb.base/list.exp: show listsize unlimited #7
	list 1
	1       #include "list0.h"
	
	Notice that "set listsize -1" actually failed with "integer 4294967295
	out of range", but we issued a PASS anyway.
	
	(and notice how the "listsize of 0 suppresses output" test passes bogusly too.)
	
	This patch fixes that testsuite problem in the obvious way.

	* gdb.base/list.exp (set_listsize): Use gdb_test_no_output for
	"set listsize".
