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.

Currently `Write` returns the number of ciphertext bytes written.
According to the docs for io.Writer, Write should return the amount
of bytes consumed from the input.
```
// Write writes len(p) bytes from p to the underlying data stream.
// It returns the number of bytes written from p (0 <= n <= len(p))
// and any error encountered that caused the write to stop early.
// Write must return a non-nil error if it returns n < len(p).
// Write must not modify the slice data, even temporarily.
Write(p []byte) (n int, err error)
```

Customer reported an issue where the connections were not closing, and
would instead just stay open. This commit makes it so that we close out
the connection regardless of what error we see. I've verified locally
that it fixes the issue, we should add a test for this.

This was just cleanup for an ancient version of Tailscale. Any such machines
have upgraded since then.

And add a CapabilityVersion type, primarily for documentation.
This makes MapRequest.Version, RegisterRequest.Version, and
SetDNSRequest.Version all use the same version, which will avoid
confusing in the future if Register or SetDNS ever changed their
semantics on Version change. (Currently they're both always 1)
This will requre a control server change to allow a
SetDNSRequest.Version value other than 1 to be deployed first.

In the future we'll probably want to run the "tailscale web"
server instead, but for now stop the infinite restart loop.

One of the current few steps to run Tailscale on gokrazy is to
specify the --tun=userspace-networking flag:
https://gokrazy.org/userguide/install/tailscale/
Instead, make it the default for now. Later we can change the
default to kernel mode if available and fall back to userspace
mode like Synology, once #391 is done.
Likewise, set default paths for Gokrazy, as its filesystem hierarchy
is not the Linux standard one. Instead, use the conventional paths as
documented at https://gokrazy.org/userguide/install/tailscale/.

When I deployed server-side changes, I put the upgrade handler at /ts2021
instead of /switch. We could move the server to /switch, but ts2021 seems
more specific and better, but I don't feel strongly.

Turns out we're pretty good already at init-time work in tailscaled.
The regexp/syntax shows up but it's hard to get rid of that; zstd even
uses regexp. *shrug*
