We can't do Noise-over-HTTP in Wasm/JS (because we don't have bidirectional
communication), but we should be able to do it over WebSockets. Reuses
derp WebSocket support that allows us to turn a WebSocket connection
into a net.Conn.

This makes it so that the user is notified that the action
they are about to take may result in them getting disconnected from
the machine. It then waits for 5s for the user to maybe Ctrl+C out of
it.
It also introduces a `--accept-risk=lose-ssh` flag for automation, which
allows the caller to pre-acknowledge the risk.
The two actions that cause this are:
- updating `--ssh` from `true` to `false`
- running `tailscale down`

AFAICT this isn't documented on MSDN, but based on the issue referenced below,
NRPT rules are not working when a rule specifies > 50 domains.
This patch modifies our NRPT rule generator to split the list of domains
into chunks as necessary, and write a separate rule for each chunk.
For compatibility reasons, we continue to use the hard-coded rule ID, but
as additional rules are required, we generate new GUIDs. Those GUIDs are
stored under the Tailscale registry path so that we know which rules are ours.
I made some changes to winutils to add additional helper functions in support
of both the code and its test: I added additional registry accessors, and also
moved some token accessors from paths to util/winutil.

I wrote this code way back at the beginning of my tenure at Tailscale when we
had concerns about needing to restore deleted machine keys from backups.
We never ended up using this functionality, and the code is now getting in the
way, so we might as well remove it.

This defines a new magic IPv6 prefix, fd7a:115c:a1e0:b1a::/64, a
subset of our existing /48, where the final 32 bits are an IPv4
address, and the middle 32 bits are a user-chosen "site ID". (which
must currently be 0000:00xx; the top 3 bytes must be zero for now)
e.g., I can say my home LAN's "site ID" is "0000:00bb" and then
advertise its 10.2.0.0/16 IPv4 range via IPv6, like:
tailscale up --advertise-routes=fd7a:115c:a1e0:b1a::bb:10.2.0.0/112
(112 being /128 minuse the /96 v6 prefix length)
Then people in my tailnet can:
$ curl '[fd7a:115c:a1e0:b1a::bb:10.2.0.230]'

This adds a "tailscale nc" command that acts a bit like "nc", but
dials out via tailscaled via localapi.
This is a step towards a "tailscale ssh", as we'll use "tailscale nc"

But this is also just useful for debugging & scripting.

We need to be able to provide the ability for the GUI clients to resolve and set
the exit node IP from an untrusted string, thus enabling the ability to specify
that information via enterprise policy.
This patch moves the relevant code out of the handler for `tailscale up`,
into a method on `Prefs` that may then be called by GUI clients.
We also update tests accordingly.

Enable use of command line arguments with tailscale cli on gokrazy. Before
this change using arguments like "up" would cause tailscale cli to be
repeatedly restarted by gokrazy process supervisor.
We never want to have gokrazy restart tailscale cli, even if user would
manually start the process.
Expected usage is that user creates files:
flags/tailscale.com/cmd/tailscale/flags.txt:
up
flags/tailscale.com/cmd/tailscaled/flags.txt:
--statedir=/perm/tailscaled/
--tun=userspace-networking
Then tailscale prints URL for user to log in with browser.
Alternatively it should be possible to use up with auth key to allow
unattended gokrazy installs.
