PR gdb/7536:
	* valprint.c (input_radix_1): New static global.
	(set_input_radix): Use it instead of "input_radix".
	(set_input_radix_1): Always leave input_radix_1 set to
	input_radix.
	(output_radix_1): New static global.
	(set_output_radix): Use it instead of "output_radix".
	(set_output_radix_1): Always leave output_radix_1 set to
	output_radix.
	(_initialize_valprint): Use "input_radix_1" instead of
	"input_radix" with the "input-radix" command.  Use
	"output_radix_1" instead of "output_radix" with the "output-radix"
	command.

	* gdb.base/radix.exp: Add tests to ensure invalid input radices
	and unsupported output radices are really rejected.
