Brad Fitzpatrick efb84ca60d ipn/localapi, cmd/tailscale: add CPU & memory profile support, debug command
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.

Brad Fitzpatrick 3c8ca4b357 client/tailscale, cmd/tailscale/cli: move version mismatch check to CLI
So people can use the package for whois checks etc without version
skew errors.

The earlier change faa891c1f2 for #1905
was a bit too aggressive.

Fixes #2757

julianknodt 506c2fe8e2 cmd/tailscale: make netcheck use active DERP map, delete static copy
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.

Brad Fitzpatrick db5e269463 client/tailscale/apitype: move local API types to new apitype package
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.

Brad Fitzpatrick 1bd14a072c cmd/tailscale, ipn/localapi: move IP forwarding check to tailscaled, API
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.

David Crawshaw e67f1b5da0 client/tailscale, cmd/tailscale/cli: plumb --socket through
Without this, `tailscale status` ignores the --socket flag on macOS and
always talks to the IPNExtension, even if you wanted it to inspect a
userspace tailscaled.
