Andrew Dunham	80b138f0df	wgengine/magicsock: keep advertising endpoints after we stop discovering them ... Previously, when updating endpoints we would immediately stop advertising any endpoint that wasn't discovered during determineEndpoints. This could result in, for example, a case where we performed an incremental netcheck, didn't get any of our three STUN packets back, and then dropped our STUN endpoint from the set of advertised endpoints... which would result in clients falling back to a DERP connection until the next call to determineEndpoints. Instead, let's cache endpoints that we've discovered and continue reporting them to clients until a timeout expires. In the above case where we temporarily don't have a discovered STUN endpoint, we would continue reporting the old value, then re-discover the STUN endpoint again and continue reporting it as normal, so clients never see a withdrawal.

James Tucker	b7f51a1468	.github/workflows: add artifact caching and remove double build on race ... Go artifact caching will help provided that the cache remains small enough - we can reuse the strategy from the Windows build where we only cache and pull the zips, but let go(1) do the many-file unpacking as it does so faster. The race matrix was building once without race, then running all the tests with race, so change the matrix to incldue a `buildflags` parameter and use that both in the build and test steps.

Mihai Parparita	edb02b63f8	net/sockstats: pass in logger to sockstats.WithSockStats ... Using log.Printf may end up being printed out to the console, which is not desirable. I noticed this when I was investigating some client logs with `sockstats: trace "NetcheckClient" was overwritten by another`. That turns to be harmless/expected (the netcheck client will fall back to the DERP client in some cases, which does its own sockstats trace). However, the log output could be visible to users if running the `tailscale netcheck` CLI command, which would be needlessly confusing.

Anton Tolchanov	8546ff98fb	tsweb: move varz handler(s) into separate modules ... This splits Prometheus metric handlers exposed by tsweb into two modules: - `varz.Handler` exposes Prometheus metrics generated by our expvar converter; - `promvarz.Handler` combines our expvar-converted metrics and native Prometheus metrics. By default, tsweb will use the promvarz handler, however users can keep using only the expvar converter. Specifically, `tailscaled` now uses `varz.Handler` explicitly, which avoids a dependency on the (heavyweight) Prometheus client.

Mihai Parparita	f49b9f75b8	util/clientmetric: allow client metric values to be provided by a function ... Adds NewGaugeFunc and NewCounterFunc (inspired by expvar.Func) which change the current value to be reported by a function. This allows some client metric values to be computed on-demand during uploading (at most every 15 seconds), instead of being continuously updated. clientmetric uploading had a bunch of micro-optimizations for memory access (#3331) which are not possible with this approach. However, any performance hit from function-based metrics is contained to those metrics only, and we expect to have very few. Also adds a DisableDeltas() option for client metrics, so that absolute values are always reported. This makes server-side processing of some metrics easier to reason about.
