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.

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)

f192c05413 metrics: add a LabelMap type for variables with 1 label dimension.
This lets us publish sets of vars that are breakdowns along one

how to do useful things with.

dbc99dc0d2 paths: use /var/db for state on BSDs, and /var/run for sockets.
On BSD, /var/db is what linux calls /var/lib.

On modern linux, /run and /var/run are the same directory, but
on BSD the correct path is /var/run, so use that.
