Right now it's not possible to perform a safe reload because we don't know what patterns were recently added or were already present. This patch adds a generation counter to the reference patterns so that it is possible to know what generation of the reference they were loaded with. A reference now has two generations, the current one, used for all additions, and the next one, allocated to those wishing to update the contents. The generation wraps at 2^32 so comparisons must be made relative to the current position. The idea will be that upon full reload, the caller will first get a new generation ID, will insert all new patterns using it, will then switch the current ID to the new one, and will delete all entries older than the current ID. This has the benefit of supporting chunked updates that remain consistent and that won't block the whole process for ages like pat_ref_reload() currently does.
