net/dns/resolver: add live reconfig, plumb through to ipnlocal.
...
The resolver still only supports a single upstream config, and
ipn/wgengine still have to split up the DNS config, but this moves
closer to unifying the DNS configs.
As a handy side-effect of the refactor, IPv6 MagicDNS records exist
now.

net/dns/resolver: unexport Resolve and ResolveReverse.
...
They're only used internally and in tests, and have surprising
semantics in that they only resolve MagicDNS names, not upstream
resolver queries.
