Brad Fitzpatrick 7b34154df2 all: deprecate Node.Capabilities (more), remove PeerChange.Capabilities [capver 89]
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.

Percy Wegmann 2d5d6f5403 ipn,wgengine: only intercept TailFS traffic on quad 100
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.

When reverse path filtering is in strict mode on Linux, using an exit
node blocks all network connectivity. This change adds a warning about

ipnlocal: force-regen new authURL when it is too old (#10971)
Fixes tailscale/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.

wgengine/magicsock: implement probing of UDP path lifetime (#10844)
This commit implements probing of UDP path lifetime on the tail end of
an active direct connection. Probing configuration has two parts -
Cliffs, which are various timeout cliffs of interest, and
CycleCanStartEvery, which limits how often a probing cycle can start,
per-endpoint. Initially a statically defined default configuration will
be used. The default configuration has cliffs of 10s, 30s, and 60s,
with a CycleCanStartEvery of 24h. Probing results are communicated via
clientmetric counters. Probing is off by default, and can be enabled
via control knob. Probing is purely informational and does not yet
drive any magicsock behaviors.

Will Norris 236531c5fc ipn/ipnserver: always allow Windows SYSTEM user to connect
When establishing connections to the ipnserver, we validate that the
local user is allowed to connect.  If Tailscale is currently being
managed by a different user (primarily for multi-user Windows installs),
we don't allow the connection.

With the new device web UI, the inbound connection is coming from
tailscaled itself, which is often running as "NT AUTHORITY\SYSTEM".
In this case, we still want to allow the connection, even though it
doesn't match the user running the Tailscale GUI. The SYSTEM user has
full access to everything on the system anyway, so this doesn't escalate
privileges.

Eventually, we want the device web UI to run outside of the tailscaled
process, at which point this exception would probably not be needed.
