On windows, allow many entries in conscache directories
...
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

On windows, don't force-unlink active conscache objects.
...
Part of a fix for bug 22752: We can't unlink these because Windows
doesn't allow you to unlink an in-use file.

If we're out of file space in the storage directory, we'll need to

Add a 'consensus cache' type on top of storagedir.
...
Every file in the cache is labeled. The labels are held in memory;
the bodies are mapped on demand.
