Fixes regression from 81cabf48ec which made
all map errors be sent to the frontend UI.

For debugging Synology. Like the existing goroutines handler, in that
it's owner-only.

github.com/go-multierror/multierror served us well.
But we need a few feature from it (implement Is),
and it's not worth maintaining a fork of such a small module.
Instead, I did a clean room implementation inspired by its API.

At least until js/wasm starts using browser LocalStorage or something.
But for the foreseeable future, any login from a browser should
be considered ephemeral as the tab can close at any time and lose
the wireguard key, never to be seen again.

iOS and Android no longer use these. They both now (as of today)
use the hostinfo.SetFoo setters instead.

Turns out the iOS client has been only sending the OS version it first
started at. This whole hostinfo-via-prefs mechanism was never a good idea.
Start removing it.

This fixes "tailscale cert" on Synology where the var directory is
typically like /volume2/@appdata/Tailscale, or any other tailscaled
user who specifies a non-standard state file location.
This is a interim fix on the way to #2932.

So if the control plane knows that something's broken about the node, it can
include problem(s) in MapResponse and "tailscale status" will show it.
(and GUIs in the future, as it's in ipnstate.Status/JSON)
This also bumps the MapRequest.Version, though it's not strictly
required. Doesn't hurt.

LocalBackend.Shutdown's docs say:
> The backend can no longer be used after Shutdown returns.
Nevertheless, TestStateMachine blithely calls Shutdown, talks some smack,
and continues on, expecting things to work. Other uses of Shutdown
in the codebase are as intended.
Things mostly kinda work anyway, except that the wgengine.Engine has been
shut down, so calls to Reconfig fail. Those get logged:
> local.go:603: wgengine status error: engine closing; no status
but otherwise ignored.
However, the Reconfig failure caused one fewer call to pause/unpause
than normal. Now the assertCalls lines match the equivalent ones
earlier in the test.
I don't see an obvious correct replacement for Shutdown in the context
of this test; I'm not sure entirely what it is trying to accomplish.
It is possible that many of the tests remaining after the prior call
to Shutdown are now extraneous. They don't harm anything, though,
so err on the side of safety and leave them for now.

Use helpers and variadic functions to make the call sites
a lot easier to read, since they occur a lot.

Concurrent calls to LocalBackend.setWgengineStatus
could result in some of the status updates being dropped.
This was exacerbated by 92077ae78c,
which increases the probability of concurrent status updates,
causing test failures (tailscale/corp#2579).
It's going to take a bit of work to fix this test.
The ipnlocal state machine is difficult to reason about,
particularly in the face of concurrency.
We could fix the test trivially by throwing a new mutex around
setWgengineStatus to serialize calls to it,
but I'd like to at least try to do better than cosmetics.
In the meantime, commit the test.

In prep for other bug fixes & tests. It's hard to test when it was
intermingled into LocalBackend.authReconfig.
Now it's a pure function.
And rename variable 'uc' (user config?) to the since idiomatic
'prefs'.

We currently plumb full URLs for DNS resolvers from the control server
down to the client. But when we pass the values into the net/dns
package, we throw away any URL that isn't a bare IP. This commit
continues the plumbing, and gets the URL all the way to the built in
forwarder. (It stops before plumbing URLs into the OS configurations
that can handle them.)

* types/key: add ControlPrivate, with custom serialization.
ControlPrivate is just a MachinePrivate that serializes differently
in JSON, to be compatible with how the Tailscale control plane
historically serialized its private key.
