So js/wasm clients can log in for a bit using regular Gmail/GitHub auth
without using an ephemeral key but still have their node cleaned up
when they're done.

Complete with converters to all the other types that represent a
node key today, so the new type can gradually subsume old ones.

So future refactors can only deal with a net.Listener and
be unconcerned with their caller's (Windows-specific) struggles.

I'll keep ipnserver.Run for compatibility, but it'll be a wrapper
around several smaller pieces. (more testable too)
For now, start untangling some things in preparation.
Plan is to have to have a constructor for the just-exported
ipnserver.Server type that takes a LocalBackend and can
accept (in a new method) on a provided listener.

It's all opaque, there's no constructor, and no exported
methods, so it's useless at this point, but this is one
small refactoring step.

Now that we multicast the SSDP query, we can get IGD offers from
devices other than the current device's default gateway. We don't want
to accidentally bind ourselves to those.

So js/wasm can override where those go, without implementing
an *os.File pipe pair, etc.

And the derper change to add a CORS endpoint for latency measurement.
And a little magicsock change to cut down some log spam on js/wasm.

There are /etc/resolv.conf files out there where resolvconf wrote
the file but pointed to systemd-resolved as the nameserver.
We're better off handling those as systemd-resolved.
> # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
> # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
> # 127.0.0.53 is the systemd-resolved stub resolver.
> # run "systemd-resolve --status" to see details about the actual nameservers.

In some containers, /etc/resolv.conf is a bind-mount from outside the container.
This prevents renaming to or from /etc/resolv.conf, because it's on a different
filesystem from linux's perspective. It also prevents removing /etc/resolv.conf,
because doing so would break the bind-mount.
If we find ourselves within this environment, fall back to using copy+delete when
renaming to /etc/resolv.conf, and copy+truncate when renaming from /etc/resolv.conf.
