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.

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.

This PR removes all async functionality from the portlist package
which may be a breaking change for non-tailscale importers. The only
importer within this codebase (LocalBackend) is already using the synchronous
API so no further action needed.

This is a follow up on PR #8172 that adds a synchronous Poll method
which allows for the Poller to be used as a zero value without needing
the constructor. The local backend is also changed to use the new API.
A follow up PR will remove the async functionality from the portlist package.

Allow calls to `WatchIPNBus` to be permformed by clients with
Readonly permissions. This brings it in line with the permissions
required for `Status`, which also exposes the similar information.
This allows clients to get realtime updates about the tailnet
in their own applications, without needing to actively poll the
`Status` endpoint.

Instead of renewing certificates based on whether or not they're expired
at a fixed 14-day period in the future, renew based on whether or not
we're more than 2/3 of the way through the certificate's lifetime. This
properly handles shorter-lived certificates without issue.

In order to improve our ability to understand the state of policies and
registry settings when troubleshooting, we enumerate all values in all subkeys.
x/sys/windows does not already offer this, so we need to call RegEnumValue
directly.
For now we're just logging this during startup, however in a future PR I plan to
also trigger this code during a bugreport. I also want to log more than just
registry.

Various BSD-derived operating systems including macOS and FreeBSD
require that ping6 be used for IPv6 destinations. The "ping" command
does not understand an IPv6 destination.
FreeBSD 13.x and later do handle IPv6 in the regular ping command,
but also retain a ping6 command. We use ping6 on all versions of
FreeBSD.

58ab66ec51 added LDAP support
for #4945 by shelling out to getdent.
It was supposed to fall back to the old method when getdent wasn't
found, but some variable name confusion (uid vs username) meant the
old path wasn't calling the right lookup function (user.LookupId
instead of user.Lookup).
Which meant that changed probably also broke FreeBSD and macOS SSH
support in addition to the reported OpenWRT regression.
The gokrazy support didn't look right either.
