allowedips: maintain per-peer list of allowedips

This makes `wg show` and `wg showconf` and the like significantly
faster, since we don't have to iterate through every node of the trie
for every single peer. It also makes netlink cursor resumption much less
problematic, since we're just iterating through a list, rather than
having to save a traversal stack.
