Make sym_change_count static, implement
void sym_change_count_set(int)
and
int sym_change_count(void)
to set or get its value;
sym_change_count is only changed by void sym_change_count_set(int).
the latter can call a callback function, if a fn-pointer is set by
also new function
void sym_change_count_changed_set(void (*fn)(int))
.
