[SERVER] Make image->users atomic and get rid of some locking
With this change it should be safe to read the users count of an image
without locking first, assuming you already have a reference on the
image or are otherwise sure it cannot be freed, i.e. in an active
uplink. Updating users, or checking whether it's 0 in order to free the
image should only be done while holding the imageListLock.
