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.

Regards, Linus
