Mihai Parparita	1ce0e558a7	cmd/derper, control/controlhttp: disable WebSocket compression The data that we send over WebSockets is encrypted and thus not compressible. Additionally, Safari has a broken implementation of compression (see nhooyr/websocket#218) that makes enabling it actively harmful.

Mihai Parparita	a9f32656f5	control/controlhttp: allow client and server to communicate over WebSockets We can't do Noise-over-HTTP in Wasm/JS (because we don't have bidirectional communication), but we should be able to do it over WebSockets.

Brad Fitzpatrick	a80cef0c13	cmd/derper: fix regression from bootstrap DNS optimization The commit `b9c92b90db` earlier today caused a regression of serving an empty map always, as it was JSON marshalling an atomic.Value instead of the DNS entries map it just built.

Joe Tsai	0173a50bf0	cmd/derper: add a rate limiter for accepting new connection (#3908 ) A large influx of new connections can bring down DERP since it spins off a new goroutine for each connection, where each routine may do significant amount of work (e.g., allocating memory and crunching numbers for TLS crypto). The momentary spike can cause the process to OOM. This commit sets the groundwork for limiting connections, but leaves the limit at infinite by default.

David Anderson	db800ddeac	cmd/derper: set Content-Security-Policy on DERPs. It's a basic "deny everything" policy, since DERP's HTTP server is very uninteresting from a browser POV.
