Mihai Parparita f0f2b2e22b logtail: increase maximum log line size in low memory mode
The 255 byte limit was chosen more than 3 years ago (tailscale/corp@929635c9d9),
when iOS was operating under much more significant memory constraints.
With iOS 15 the network extension has an increased limit, so increasing
it to 4K should be fine.

The motivating factor was that the network interfaces being logged
by linkChange in wgengine/userspace.go were getting truncated, and it
would be useful to know why in some cases we're choosing the pdp_ip1
cell interface instead of the pdp_ip0 one.

Maisem Ali 0fd2f71a1e ipn/ipnlocal: use presence of NodeID to identify logins
The profileManager was using the LoginName as a proxy to figure out if the profile
had logged in, however the LoginName is not present if the node was created with an
Auth Key that does not have an associated user.

Andrew Dunham 6d84f3409b ipn/ipnlocal: handle more edge cases in netmap expiry timer
We now handle the case where the NetworkMap.SelfNode has already expired
and do not return an expiry time in the past (which causes an ~infinite
loop of timers to fire).

Additionally, we now add an explicit check to ensure that the next
expiry time is never before the current local-to-the-system time, to
ensure that we don't end up in a similar situation due to clock skew.

Finally, we add more tests for this logic to ensure that we don't
regress on these edge cases.

Fixes #7193

Mihai Parparita 0e3fb91a39 net/dns/resolver: remove maxDoHInFlight
It was originally added to control memory use on iOS (#2490), but then
was relaxed conditionally when running on iOS 15 (#3098). Now that we
require iOS 15, there's no need for the limit at all, so simplify back
to the original state.

Mihai Parparita b6908181ff net/tshttpproxy: more directly use Transport proxy CONNECT hooks
GetProxyConnectHeader (golang/go#41048) was upstreamed in Go 1.16 and
OnProxyConnectResponse (golang/go#54299) in Go 1.20, thus we no longer
need to guard their use by the tailscale_go build tag.

Andrew Dunham 2755f3843c health, net/tlsdial: add healthcheck for self-signed cert
When we make a connection to a server, we previously would verify with
the system roots, and then fall back to verifying with our baked-in
Let's Encrypt root if the system root cert verification failed.

We now explicitly check for, and log a health error on, self-signed
certificates. Additionally, we now always verify against our baked-in
Let's Encrypt root certificate and log an error if that isn't
successful. We don't consider this a health failure, since if we ever
change our server certificate issuer in the future older non-updated
versions of Tailscale will no longer be healthy despite being able to
connect.

nix: update nixpkgs flake, override go_1_20 for tailscale_go (#7139)
Bleeding edge Tailscale Nix flake broke after updating to go1.20rc3.

Go 1.20 moved to Go 1.17 as a bootstarp toolchain. Fortunately nixpkgs
nixos-unstable already had a 1.20.nix with bootstrap117.nix.

```
❯ ./result/bin/tailscale version
1.37.0-dev
  track: unstable (dev); frequent updates and bugs are likely

Anton Tolchanov 100d8e909e cmd/derpprobe: migrate to the prober framework
`prober.DERP` was created in #5988 based on derpprobe. Having used it
instead of derpprobe for a few months, I think we have enough confidence
that it works and can now migrate derpprobe to use the prober framework
and get rid of code duplication.

A few notable changes in behaviour:
- results of STUN probes over IPv4 and IPv6 are now reported separately;
- TLS probing now includes OCSP verification;
- probe names in the output have changed;
- ability to send Slack notification from the prober has been removed.
  Instead, the prober now exports metrics in Expvar (/debug/vars) and
  Prometheus (/debug/varz) formats.

Fixes https://github.com/tailscale/corp/issues/8497
