Why not turn last_dht_update into a bool and apply the timeout length based on that bool.

I wasn't sure how to smoothly toggle a DAT entry from local to global or the other way round without adding locks, several 'if()'s and hackish adjustments of 'last_update'.

Therefore I went for a split the hash table in two in v3: One for the DAT cache and one for the DAT DHT. Kind of similar to how we have two tables for the TT for two distinct concepts as well.

While this might need a few more lines of code the result seemed less complicated and cleaner.
