There were cases in the code where time calculations and comparisons were overflowing and causing connection instability. This will keep time calculations within expected ranges.

(1) Public networks now get COMs even though they do not gate with them since they will need them to push auth for multicast stuff, (2) added a bunch of rate limit circuit breakers for anti-DOS, (3) cleanup.

IPv6 links are unfortunately not "reliable." Many IPv6 gateways, while not
...
implementing NAT, do implement stateful firewalling with absurdly short
timeouts (<60s). Keepalives are still required in IPv6.
Network engineers continue to mindlessly carry forward cruft and baggage
from IPv4 to IPv6.

Tighten up dead path detection. Should now auto-detect dead paths in less than 10 seconds at a very small cost in ECHO requests (or HELLOs for older peers). GitHib issue #272
