95470c3448 net/dns: remove Cleanup manager parameter.
It's only use to skip some optional initialization during cleanup,
but that work is very minor anyway, and about to change drastically.

cf361bb9b1 net/dns: remove PerDomain from Config.
It's currently unused, and no longer makes sense with the upcoming
DNS infrastructure. Keep it in tailcfg for now, since we need protocol
compat for a bit longer.

9f105d3968 net/dns/resolver: teach the forwarder to do per-domain routing.
Given a DNS route map, the forwarder selects the right set of
upstreams for a given name.

90f82b6946 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.

dbe4f6f42d 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.
