Jason A. Donenfeld 8cc99631d0 device: use linked list for per-peer allowed-ip traversal 
This makes the IpcGet method much faster.

We also refactor the traversal API to use a callback so that we don't
need to allocate at all. Avoiding allocations we do self-masking on
insertion, which in turn means that split intermediate nodes require a
copy of the bits.

This benchmark is good, though it's only for a pair of peers, each with
only one allowedips. As this grows, the delta expands considerably.
