Brad Fitzpatrick	19b0cfe89e	all: prepare for GOOS=ios in Go 1.16 ... Work with either way for now on iOS (darwin/arm64 vs ios/arm64). In February when Go 1.16 comes out we'll have a universal binary for darwin/arm64 (macOS) and will drop support for Go 1.15 and its darwin/amd64 meaning iOS. (it'll mean macOS).

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)	5 years ago
