Tailscale attempts to determine if resolvconf or openresolv
is in use by running `resolvconf --version`, under the assumption
this command will error when run with Debian's resolvconf. This
assumption is no longer true and leads to the wrong commands being
run on newer versions of Debian with resolvconf >= 1.90. We can
now check if the returned version string starts with "Debian resolvconf"
if the command is successful.

Add an explicit accept rule for input to the tun interface, as a mirror
to the explicit rule to accept output from the tun interface.
The rule matches any packet in to our tun interface and accepts it, and
the rule is positioned and prioritized such that it should be evaluated
prior to conventional ufw/iptables/nft rules.

This is only relevant for unstable releases and local builds. When local
version is newer than upstream, abort release.
Also, re-add missing newlines in output that were missed in
https://github.com/tailscale/tailscale/pull/9694.

The whois handler was documented as taking IP (e.g. 100.101.102.103)
or IP:port (e.g. usermode 127.0.0.1:1234) but that got broken at some point
and we started requiring a port always. Fix that.
Also, found in the process of adding tests: fix the CapMap lookup in
userspace mode (it was always returning the caps of 127.0.0.1 in
userspace mode). Fix and test that too.

I was reviewing some code that was performing this by hand, and wanted
to suggest using syncs.Map, however as the code in question was
allocating a non-trivial structure this would be necessary to meet the
target.

Over time all taildrop functionality will be contained in the

The Port.Pid was always more of an implementation detail on some
platforms and isn't necessary on Linux so it was never populated.
(Nothing outside the portlist package ever used it)
But might as well populate it for consistency since we have it in
memory and its absence confused people.

Partially reverts 1bd3edbb46 (but keeps part of it)
iptables is almost always required but not strictly needed. Even if
you can technically run Tailscale without it (by manually configuring
nftables or userspace mode), we still now mark this as "Depends"
because our previous experiment in
https://github.com/tailscale/tailscale/issues/9236 of making it only
Recommends caused too many problems. Until our nftables table is more
mature, we'd rather err on the side of wasting a little disk by
including iptables for people who might not need it rather than
handle reports of it being missing.

Instead of just falling back to making a TCP query to an upstream DNS
server when the UDP query returns a truncated query, also start a TCP
query in parallel with the UDP query after a given race timeout. This
ensures that if the upstream DNS server does not reply over UDP (or if
the response packet is blocked, or there's an error), we can still make
queries if the server replies to TCP queries.
This also adds a new package, util/race, to contain the logic required for
racing two different functions and returning the first non-error answer.
