David Anderson	2839854994	wgengine/magicsock: never set a DERP server as a roamAddr. ... DERP traffic is asymmetric by design, with nodes always sending to their peer's home DERP server. However, if roamAddr is set, magicsock will always push data there, rather than let DERP server selection do its thing, so we end up accidentally creating a symmetric flow.

Brad Fitzpatrick	2cff9016e4	net/dnscache: add overly simplistic DNS cache package for selective use ... I started to write a full DNS caching resolver and I realized it was overkill and wouldn't work on Windows even in Go 1.14 yet, so I'm doing this tiny one instead for now, just for all our netcheck STUN derp lookups, and connections to DERP servers. (This will be caching a exactly 8 DNS entries, all ours.) Fixes #145 (can be better later, of course)	2020-03-05 12:23:37 -08:00
