I would normally only give references when asked. One reason being that I would always inform a referee that they should expect to be contacted - that's not true if I just send my CV, only once I have an offer. I wouldn't expect a prospective employeer to ask for references unless they had made an offer as the references would be expected to include the current employeer. Clearly your circumstances are somewhat different, but we can expect the same overall guidelines to apply.
