Brad Fitzpatrick fc12cbfcd3 client/tailscale, cmd/tailscale, localapi: add 'tailscale nc'
This adds a "tailscale nc" command that acts a bit like "nc", but
dials out via tailscaled via localapi.

This is a step towards a "tailscale ssh", as we'll use "tailscale nc"
as a ProxyCommand for in some cases (notably in userspace mode).

But this is also just useful for debugging & scripting.

Updates #3802

Brad Fitzpatrick c37af58ea4 net/tsdial: move more weirdo dialing into new tsdial package, plumb
Not done yet, but this move more of the outbound dial special casing
from random packages into tsdial, which aspires to be the one unified
place for all outbound dialing shenanigans.

Then this plumbs it all around, so everybody is ultimately
holding on to the same dialer.

As of this commit, macOS/iOS using an exit node should be able to
reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt
to stay within the Network Extension.

A number of steps remain, including but limited to:

* move a bunch more random dialing stuff

* make netstack-mode tailscaled be able to use exit node's DNS proxy,
  teaching tsdial's resolver to use it when an exit node is in use.

Brad Fitzpatrick 3b3994f0db ipn{,/localapi,ipnlocal}: infer cert dir from state file location
This fixes "tailscale cert" on Synology where the var directory is
typically like /volume2/@appdata/Tailscale, or any other tailscaled
user who specifies a non-standard state file location.

This is a interim fix on the way to #2932.

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 98ad7f279c ipn/localapi: fix inability to receive taildrop files w/ escaped names
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.

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.
