* cmd/tailscale/cli: make `tailscale update` query `softwareupdate`
Even on macOS when Tailscale was installed via the App Store, we can check for
and even install new versions if people ask explicitly. Also, warn if App Store
AutoUpdate is not turned on.

In late 2022 a subtle but crucial part of documentation was added to ed25519.Verify: It
will panic if len(publicKey) is not [PublicKeySize].
02ed0e5e67
This change catches that error so it won't lead to a panic.

Allow inline CSS for debug handlers to make prototyping easier. These
are generally not accessible to the public and the small risk of CSS
injection via user content seems acceptable.
Also allow form submissions on the same domain, instead of banning all
forms. An example of such form is

This changes the ACLTestError type to reuse the existing/identical
types from the ACL implementation, to avoid issues in the future if
the two types fall out of sync.

This commit adds nftable rule injection for tailscaled. If tailscaled is
started with envknob TS_DEBUG_USE_NETLINK_NFTABLES = true, the router
will use nftables to manage firewall rules.

The MacOS client can't set the MTU when creating the tun due to lack
of permissions, so add it to the router config and have MacOS set it
in the callback using a method that it does have permissions for.

If the absolute value of the difference between the current
PreferredDERP's latency and the best latency is <= 10ms, don't change
it and instead prefer the previous value.
This is in addition to the existing hysteresis that tries to remain
on the previous DERP region if the relative improvement is small, but
handles nodes that have low latency to >1 DERP region better.

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
string "host".

We were never resetting the backoff in streaming mapResponses.
The call to `PollNetMap` always returns with an error. Changing that contract
is harder, so manually reset backoff when a netmap is received.

When performing a fallback DNS query, run the recursive resolver in a
separate goroutine and compare the results returned by the recursive
resolver with the results we get from "regular" bootstrap DNS. This will
allow us to gather data about whether the recursive DNS resolver works
better, worse, or about the same as "regular" bootstrap DNS.

This change removes the noV4/noV6 check from addrForSendWireGuardLocked.
On Android, the client panics when reaching `rand.Intn()`, likely due to
the candidates list being containing no candidates. The suspicion is
that the `noV4` and the `noV6` are both being triggered causing the
loop to continue.
