Comment 3 for bug 1464709

There are several places in the code that would like to know what statuses are "available-equivalent". Should we use this in all those?

One drawback I can come up with: the hold targetter could end up pulling useless copies to test. But it will still look at the status' holdable flag, and allows for more flexibility in configuration. It would also keep us from missing the inclusion of "reserves" as has happened in some places.

If we wanted to do that, the flag should probably be renamed to "is_available" or the like.

Thoughts?
