+Subject: Declare function parameters as required by C23
+
+In C23, having no parameter in a function declaration no longer means an
+"unspecified" number of arguments [1]. Therefore, this code fails to
+build with this standard. Declare the missing function arguments, so
+that it compiles once again with the default standard from modern
+compilers, such as GCC 15.
+
+The exception here is the set_{basic,scientific}_object_data functions,
+which actually don't use their argument at all. Thus, their unique calls
+are changed instead.
+
+Because functions registered by set_disp_ctrl_object_data don't receive
+a button pointer as argument as the others, declare a new struct for
+holding the entries for that. It is named after "display" as it is only
+used for display control buttons.
