Since we can't be sure that we can unlink enough files on windows here, let's let the number of permitted entries grow huge if it really must. We do this by letting the storagedir hold lots of entries, but still trying to keep the number of entries under the configured limit. We also have to tell consdiffmgr not to freak out if it can't actually remove enough entries. Part of a fix for bug 22752
