Brad Fitzpatrick aefb1531d1 net/tsdial, ipn/ipnlocal: stop using netmap.NetworkMap in Dialer ... tsdial.Dialer.SetNetMap rebuilt an O(n peers) map of MagicDNS names on every netmap change. As we move toward per-peer incremental deltas, this becomes quadratic. This removes it and replaces it with SetResolveMagicDNS, a callback into LocalBackend that looks up hostnames from nodeBackend's new nodeByName index (populated alongside nodeByAddr/nodeByKey on both full and delta paths). The index stores both FQDNs and short names as keys. This is the same treatment applied to netlog (8f210454d), wglog (988b0905b), and drive (1d6989408): stop pushing *netmap.NetworkMap into subsystems and instead have them pull from LocalBackend's live data via callbacks.
