ipn/{ipnlocal,localapi}: actually renew certs before expiry (#8731)
While our `shouldStartDomainRenewal` check is correct, `getCertPEM`
would always bail if the existing cert is not expired. Add the same
`shouldStartDomainRenewal` check to `getCertPEM` to make it proceed with
renewal when existing certs are still valid but should be renewed.

The extra check is expensive (ARI request towards LetsEncrypt), so cache
the last check result for 1hr to not degrade `tailscale serve`
performance.

Also, asynchronous renewal is great for `tailscale serve` but confusing
for `tailscale cert`. Add an explicit flag to `GetCertPEM` to force a
synchronous renewal for `tailscale cert`.

Fixes #8725

Charlotte Brandhorst-Satzkorn 35bdbeda9f cli: introduce exit-node subcommand to list and filter exit nodes
This change introduces a new subcommand, `exit-node`, along with a
subsubcommand of `list` and a `--filter` flag.

Exit nodes without location data will continue to be displayed when
`status` is used. Exit nodes with location data will only be displayed
behind `exit-node list`, and in status if they are the active exit node.

The `filter` flag can be used to filter exit nodes with location data by
country.

Exit nodes with Location.Priority data will have only the highest
priority option for each country and city listed. For countries with
multiple cities, a <Country> <Any> option will be displayed, indicating
the highest priority node within that country.

Maisem Ali 1ecc16da5f tailcfg,ipn/ipnlocal,wgengine: add values to PeerCapabilities
Define PeerCapabilty and PeerCapMap as the new way of sending down
inter-peer capability information.

Previously, this was unstructured and you could only send down strings
which got too limiting for certain usecases. Instead add the ability
to send down raw JSON messages that are opaque to Tailscale but provide
the applications to define them however they wish.

Also update accessors to use the new values.

Will Norris f8b0caa8c2 serve: fix hostname for custom http ports
When using a custom http port like 8080, this was resulting in a
constructed hostname of `host.tailnet.ts.net:8080.tailnet.ts.net` when
looking up the serve handler. Instead, strip off the port before adding
the MagicDNS suffix.

Also use the actual hostname in `serve status` rather than the literal

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.

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).

James Tucker 095d3edd33 ipn/ipnlocal: reenable profile tests on Windows
This fix does not seem ideal, but the test infrastructure using a local
goos doesn't seem to avoid all of the associated challenges, but is
somewhat deeply tied to the setup.

The core issue this addresses for now is that when run on Windows there
can be no code paths that attempt to use an invalid UID string, which on
Windows is described in [1].

For the goos="linux" tests, we now explicitly skip the affected
migration code if runtime.GOOS=="windows", and for the Windows test we
explicitly use the running users uid, rather than just the string
"user1". We also now make the case where a profile exists and has
already been migrated a non-error condition toward the outer API.

Mihai Parparita 7330aa593e all: avoid repeated default interface lookups
On some platforms (notably macOS and iOS) we look up the default
interface to bind outgoing connections to. This is both duplicated
work and results in logspam when the default interface is not available
(i.e. when a phone has no connectivity, we log an error and thus cause
more things that we will try to upload and fail).

Fixed by passing around a netmon.Monitor to more places, so that we can
use its cached interface state.

We're using it in more and more places, and it's not really specific to
our use of Wireguard (and does more just link/interface monitoring).

Also removes the separate interface we had for it in sockstats -- it's

via other paths) that it's not worth the extra complexity.

Aaron Klotz 90fd04cbde ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled
I realized that a lot of the problems that we're seeing around migration and
LocalBackend state can be avoided if we drive Windows pref migration entirely
from within tailscaled. By doing it this way, tailscaled can automatically
perform the migration as soon as the connection with the client frontend is
established.

Since tailscaled is already running as LocalSystem, it already has access to
the user's local AppData directory. The profile manager already knows which
user is connected, so we simply need to resolve the user's prefs file and read
it from there.

Of course, to properly migrate this information we need to also check system
policies. I moved a bunch of policy resolution code out of the GUI and into
a new package in util/winutil/policy.
