This commit fixes a race condition where `tailscale up --force-reauth` would
exit prematurely on an already-logged in device.
Previously, the CLI would wait for IPN to report the "Running" state and then
exit. However, this could happen before the new auth URL was printed, leading
to two distinct issues:
* **Without seamless key renewal:** The CLI could exit immediately after
the `StartLoginInteractive` call, before IPN has time to switch into
the "Starting" state or send a new auth URL back to the CLI.
* **With seamless key renewal:** IPN stays in the "Running" state
throughout the process, so the CLI exits immediately without performing
any reauthentication.
The fix is to change the CLI's exit condition.
Instead of waiting for the "Running" state, if we're doing a `--force-reauth`
we now wait to see the node key change, which is a more reliable indicator
that a successful authentication has occurred.

Expand the integration tests to cover a wider range of scenarios, including:
* Before and after a successful initial login
* Auth URLs and auth keys
* With and without the `--force-reauth` flag
* With and without seamless key renewal
These tests expose a race condition when using `--force-reauth` on an
already-logged in device. The command completes too quickly, preventing
the auth URL from being displayed. This issue is identified and will be
fixed in a separate commit.

This followup patch adds the following cleanups:

the package name.
2. Rename the `derpserver.NewServer` constructor to `derpserver.New`

to be used by the new derpserver package, as now used by cmd/derper.
And then enough other misc changes to lock in that cmd/tailscaled can
be configured to not bring in tailscale.com/client/local. (The webclient
in particular, even when disabled, was bringing it in, so that's now fixed)

This is step 4 of making syspolicy a build-time feature.
This adds a policyclient.Get() accessor to return the correct
implementation to use: either the real one, or the no-op one. (A third
type, a static one for testing, also exists, so in general a
policyclient.Client should be plumbed around and not always fetched
via policyclient.Get whenever possible, especially if tests need to use
alternate syspolicy)

Step 4 of N. See earlier commits in the series (via the issue) for the
plan.
This adds the missing methods to policyclient.Client and then uses it
everywhere in ipn/ipnlocal and locks it in with a new dep test.
Still plenty of users of the global syspolicy elsewhere in the tree,
but this is a lot of them.

Step 3 in the series. See earlier cc532efc20 and d05e6dc09e.
This step moves some types into a new leaf "ptype" package out of the
big "settings" package. The policyclient.Client will later get new
methods to return those things (as well as Duration and Uint64, which
weren't done at the time of the earlier prototype).

This is step 1 of ~3, breaking up #14720 into reviewable chunks, with
the aim to make syspolicy be a build-time configurable feature.
In this first (very noisy) step, all the syspolicy string key
constants move to a new constant-only (code-free) package. This will
make future steps more reviewable, without this movement noise.
There are no code or behavior changes here.
The future steps of this series can be seen in #14720: removing global
funcs from syspolicy resolution and using an interface that's plumbed
around instead. Then adding build tags.

CONNECT proxy, we should've been able to do a TLS CONNECT request to
e.g. controlplane.tailscale.com:443 through that, and I'm pretty sure
it used to work, but refactorings and lack of integration tests made
it regress.
It probably regressed when we added the baked-in LetsEncrypt root cert
validation fallback code, which was testing against the wrong hostname
(the ultimate one, not the one which we were being asked to validate)

Previously all tests shared their tailscale+tailscaled binaries in
system /tmp directories, which often leaked, and required TestMain to
clean up (which feature/taildrop didn't use).
This makes it use testing.T.TempDir for the binaries, but still only
builds them once and efficiently as possible depending on the OS
copies them around between each test's temp dir.

ResourceCheck was previously using cmp.Diff on multiline goroutine stacks
The produced output was difficult to read for a number of reasons:
- the goroutines were sorted by count, and a changing count caused them to
jump around
- diffs would be in the middle of stacks
Instead, we now parse the pprof/goroutines?debug=1 format goroutines and
only diff whole stacks.

This adds netx.DialFunc, unifying a type we have a bazillion other
places, giving it now a nice short name that's clickable in
editors, etc.
That highlighted that my earlier move (03b47a55c7) of stuff from
nettest into netx moved too much: it also dragged along the memnet
impl, meaning all users of netx.DialFunc who just wanted netx for the
type definition were instead also pulling in all of memnet.
So move the memnet implementation netx.Network into memnet, a package
we already had.
Then use netx.DialFunc in a bunch of places. I'm sure I missed some.
And plenty remain in other repos, to be updated later.

standard library's foo package, so "netx" seems consistent.

In this PR, we update ipnlocal.LocalBackend to allow registering callbacks for control client creation
and profile changes. We also allow to register ipnauth.AuditLogFunc to be called when an auditable
action is attempted.
We then use all this to invert the dependency between the auditlog and ipnlocal packages and make
the auditlog functionality optional, where it only registers its callbacks via ipnlocal-provided hooks
when the auditlog package is imported.
We then underscore-import it when building tailscaled for Windows, and we'll explicitly
import it when building xcode/ipn-go-bridge for macOS. Since there's no default log-store
location for macOS, we'll also need to call auditlog.SetStoreFilePath to specify where
pending audit logs should be persisted.
