First we had Capabilities []string. Then
https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a
superset of Capabilities. Except we never really finished the
transition inside the codebase to go all-in on CapMap. This does so.
Notably, this coverts Capabilities on the wire early to CapMap
internally so the code can only deal in CapMap, even against an old
control server.
In the process, this removes PeerChange.Capabilities support, which no
known control plane sent anyway. They can and should use
PeerChange.CapMap instead.

node attributes was more acceptable. But now more code and more users
are using increasingly more node attributes. Time to make it a map.

If the client uses the default Tailscale control URL, validate that all
PopBrowserURLs are under tailscale.com or *.tailscale.com. This reduces
the risk of a compromised control plane opening phishing pages for
example.
The client trusts control for many other things, but this is one easy
way to reduce that trust a bit.

This is a temporary solution to at least omit Mullvad exit nodes
from the list of TailFS peers. Once we can identify peers that are
actually sharing via TailFS, we can remove this, but for alpha it'll
be sufficient to just omit Mullvad.

Moving logic that manipulates a ServeConfig into recievers on the
ServeConfig in the ipn package. This is setup work to allow the
web client and cli to both utilize these shared functions to edit
the serve config.
Any logic specific to flag parsing or validation is left untouched
in the cli command. The web client will similarly manage its
validation of user's requested changes. If validation logic becomes
similar-enough, we can make a serve util for shared functionality,
which likely does not make sense in ipn.

This fixes a regression introduced with 993acf4 and released in
v1.60.0.
The regression caused us to intercept all userspace traffic to port
8080 which prevented users from exposing their own services to their
tailnet at port 8080.
Now, we only intercept traffic to port 8080 if it's bound for
100.100.100.100 or fd7a:115c:a1e0::53.

(cherry picked from commit 17cd0626f3)
This adds a method to wgengine.Engine and plumbed down into magicsock
to add a way to get a type-safe Tailscale-safe wrapper around a
wireguard-go device.Peer that only exposes methods that are safe for
Tailscale to use internally.
It also removes HandshakeAttempts from PeerStatusLite that was just
added as it wasn't needed yet and is now accessible ala cart as needed
from the Peer type accessor.
None of this is used yet.

When reverse path filtering is in strict mode on Linux, using an exit
node blocks all network connectivity. This change adds a warning about
this to `tailscale status` and the logs.
Example in `tailscale status`:
```
- not connected to home DERP region 22
- The following issues on your machine will likely make usage of exit nodes impossible: [interface "eth0" has strict reverse-path filtering enabled], please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310
```
Example in the logs:
```
2024/02/21 21:17:07 health("overall"): error: multiple errors:

Fixestailscale/support-escalations#23.
authURLs returned by control expire after 1 hour from creation. Customer reported that the Tailscale client on macOS would sending users to a stale authentication page when clicking on the `Login...` menu item. This can happen when clicking on Login after leaving the device unattended for several days. The device key expires, leading to the creation of a new authURL, however the client doesn't keep track of when the authURL was created. Meaning that `login-interactive` would send the user to an authURL that had expired server-side a long time before.
This PR ensures that whenever `login-interactive` is called via LocalAPI, an authURL that is too old won't be used. We force control to give us a new authURL whenever it's been more than 30 minutes since the last authURL was sent down from control.
