ssh/tailssh: fix double race condition with non-pty command (#8405)
There are two race conditions in output handling.

The first race condition is due to a misuse of exec.Cmd.StdoutPipe.
The documentation explicitly forbids concurrent use of StdoutPipe
with exec.Cmd.Wait (see golang/go#60908) because Wait will
close both sides of the pipe once the process ends without
any guarantees that all data has been read from the pipe.
To fix this, we allocate the os.Pipes ourselves and
manage cleanup ourselves when the process has ended.

The second race condition is because sshSession.run waits
upon exec.Cmd to finish and then immediately proceeds to call ss.Exit,
which will close all output streams going to the SSH client.
This may interrupt any asynchronous io.Copy still copying data.
To fix this, we close the write-side of the os.Pipes after
the process has finished (and before calling ss.Exit) and
synchronously wait for the io.Copy routines to finish.

Fixes #7601

Derek Burdick dc5bc32d8f ssh/tailssh: change to user directory when running login/command
On redhat 9 and similarly locked down systems, root user does not have
access to a users directory. This fix does not set a directory for the
incubator process and instead sets the directory when the actual process
requested by remote user is executed.

Sonia Appasamy 0f5090c526 ipn/ipnlocal: add docs header to serve HTTP proxy
Adds a `Tailscale-Headers-Info` header whenever the `Tailscale-User-`
headers are filled from the HTTP proxy handler.

Planning on hooking this shorturl up to KB docs about the header
values (i.e. what's a login name vs. display name) and security
considerations to keep in mind while using these headers - notibly
that they can also be filled from external requests that do not hit
tailscaled.

prober: allow monitoring of nodes marked as STUN only in default derpmap (#8391)
prober uses NewRegionClient() to connect to a derper using a faked up
single-node region, but NewRegionClient() fails to connect if there is
no non-STUN only client in the region. Set the STUN only flag to false
before we call NewRegionClient() so we can monitor nodes marked as
STUN only in the default derpmap.

Maisem Ali 2ae670eb71 ssh/tailssh: work around lack of scontext in SELinux
Trying to SSH when SELinux is enforced results in errors like:

```
➜  ~ ssh ec2-user@<ip>
Last login: Thu Jun  1 22:51:44 from <ip2>
ec2-user: no shell: Permission denied
Connection to <ip> closed.
```

while the `/var/log/audit/audit.log` has
```
type=AVC msg=audit(1685661291.067:465): avc:  denied  { transition } for  pid=5296 comm="login" path="/usr/bin/bash" dev="nvme0n1p1" ino=2564 scontext=system_u:system_r:unconfined_service_t:s0 tcontext=unconfined_u:unconfined_r:unconfined_t:s0 tclass=process permissive=0
```

The right fix here would be to somehow install the appropriate context when
tailscale is installed on host, but until we figure out a way to do that
stop using the `login` cmd in these situations.

Sonia Appasamy e1cdcf7708 ipn/ipnlocal: add identity headers to HTTP serve proxy
Adds two new headers to HTTP serve proxy:
- `Tailscale-User-Login`: Filled with requester's login name.
- `Tailscale-User-Name`: Filled with requester's display name.

These headers only get filled when the SrcAddr is associated with
a non-tagged (i.e. user-owned) node within the client's Tailnet.

The headers are passed through empty when the request originated
from another tailnet, or the public internet (via funnel).

Andrew Dunham f077b672e4 net/dns/recursive: add initial implementation of recursive DNS resolver
We've talked in the past about reworking how bootstrap DNS works to
instead do recursive DNS resolution from the root; this would better
support on-prem customers and Headscale users where the DERP servers
don't currently resolve their DNS server. This package is an initial
implementation of recursive resolution for A and AAAA records.

Andrew Dunham 2a9d46c38f wgengine/magicsock: prefer private endpoints to public ones
Switch our best address selection to use a scoring-based approach, where
we boost each address based on whether it's a private IP or IPv6.

For users in cloud environments, this biases endpoint selection towards
using an endpoint that is less likely to cost the user money, and should
be less surprising to users.

This also involves updating the tests to not use private IPv4 addresses;
other than that change, the behaviour should be identical for existing
endpoints.
