Josh Bleecher Snyder 24db1a3c9b safesocket: print full lsof command on failure
This makes it easier to manually run the command
to discover why it is failing.

Josh Bleecher Snyder 130c5e727b safesocket: reduce log spam while running integration tests
Instead of logging lsof execution failures to stdout,
incorporate them into the returned error.

While we're here, make it clear that the file
success case always returns a nil error.

Josh Bleecher Snyder 7a08c159e6 safesocket: create the test socket in a temp dir
This allows the test to be run inside a mounted filesystem,
which I'm doing now as a I develop on a linux VM.

Fixes #2367.

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.

Brad Fitzpatrick f11cb811cc safesocket: support finding tailscale port/auth token from sandboxed CLI
Previously the CLI could only find the HTTP auth token when running
the CLI outside the sandbox, not like
/Applications/Tailscale.app/Contents/MacOS/Tailscale when that was
from the App Store.

And open up socket permissions like Linux, now that we know who

This uses the new inet.af/peercred that supports Linux and Darwin at

Brad Fitzpatrick 54d0d83b67 safesocket: on Linux, make /var/run/tailscale be 0755
Continuation of earlier two umask changes,
5611f290eb and
d6e9fb1df0.

This change mostly affects us, running tailscaled as root by hand (wit
a umask of 0077), not under systemd. End users running tailscaled
under systemd won't have a umask.

Brad Fitzpatrick 5611f290eb ipn, ipnserver: only require sudo on Linux for mutable CLI actions
This partially reverts d6e9fb1df0, which modified the permissions
on the tailscaled Unix socket and thus required "sudo tailscale" even
for "tailscale status".

Instead, open the permissions back up (on Linux only) but have the
server look at the peer creds and only permit read-only actions unless
you're root.

In the future we'll also have a group that can do mutable actions.

On OpenBSD and FreeBSD, the permissions on the socket remain locked
down to 0600 from d6e9fb1df0.

David Anderson 4460bd638b safesocket: simplify API.
On unix, we want to provide a full path to the desired unix socket.

On windows, currently we want to provide a TCP port, but someday
we'll also provide a "path-ish" object for a named pipe.

For now, simplify the API down to exactly a path and a TCP port.
