mark *_varobj_ops as "extern"

The AIX linker pointed out that gdb had multiple definitions of the
various *_varobj_ops objects.  This patch fixes the problem by marking
the declarations as "extern" in varobj.h.  Tested by rebuilding on
x86-64 Fedora 18 and on AIX.

	* varobj.h (c_varobj_ops, cplus_varobj_ops, java_varobj_ops)
	(ada_varobj_ops): Mark "extern".
