hashtables: allow up to 2^{20} peers per interface
This allows for nearly 1 million peers per interface, which should be
more than enough. If needed later, this number could easily be increased
beyond this.
We also increase the size of the hashtables to accommodate this upper
bound. In the future, it might be smart to dynamically expand the
hashtable instead of this hard coded compromise value between small
systems and large systems.
Ongoing work includes figuring out the most optimal scheme for these
hashtables and for the insertion to mask their order from timing
inference.
