This was already possible on Linux if you ran tailscaled with --debug
(which runs net/http/pprof), but it requires the user have the Go
toolchain around.
Also, it wasn't possible on macOS, as there's no way to run the IPNExtension
with a debug server (it doesn't run tailscaled).
And on Windows it's super tedious: beyond what users want to do or
what we want to explain.
Instead, put it in "tailscale debug" so it works and works the same on
all platforms. Then we can ask users to run it when we're debugging something
and they can email us the output files.

The localapi was double-unescaping: once by net/http populating
the URL, and once by ourselves later. We need to start with the raw
escaped URL if we're doing it ourselves.
Started to write a test but it got invasive. Will have to add those
tests later in a commit that's not being cherry-picked to a release
branch.

After allowing for custom DERP maps, it's convenient to be able to see their latency in
netcheck. This adds a query to the local tailscaled for the current DERPMap.

They were scattered/duplicated in misc places before.
It can't be in the client package itself for circular dep reasons.
This new package is basically tailcfg but for localhost
communications, instead of to control.

Adding a subcommand which prints and logs a log marker. This should help
diagnose any issues that users face.

Instead of having the CLI check whether IP forwarding is enabled, ask
tailscaled. It has a better idea. If it's netstack, for instance, the
sysctl values don't matter. And it's possible that only the daemon has
permission to know.
