[obv] Make 'disable_display' static.

[Yao Qi <yao@codesourcery.com>]

Hi,
disable_display is only called by disable_current_display in
printcmd.c, so we can make it static.  I'll apply it in two days.

gdb:

	* breakpoint.h (disable_display): Remove declaration.
	* printcmd.c (disable_display): Make it static.
