This commit adds a new method to the tsnet.Server type named `Logger`
that returns the underlying logtail instance's Logf method.
This is intended to be used within the Kubernetes operator to wrap its
existing logger in a way such that operator specific logs can also be
sent to control for support & debugging purposes.

As of this commit (per the issue), the Taildrive code remains where it
was, but in new files that are protected by the new ts_omit_drive
build tag. Future commits will move it.

Its doc said its signature matched a std signature, but it used
Tailscale-specific types.
Nowadays it's the caller (func control) that curries the logf/netmon
and returns the std-matching signature.

Removes ACL edits from e2e tests in favour of trying to simplify the
tests and separate the actual test logic from the environment setup
logic as much as possible. Also aims to fit in with the requirements
that will generally be filled anyway for most devs working on the
operator; in particular using tags that fit in with our documentation.

This adds a file that's not compiled by default that exists just to
make it easier to do binary size checks, probing what a binary would
be like if it included reflect methods (as used by html/template, etc).
As an example, once tailscaled uses reflect.Type.MethodByName(non-const-string) anywhere,
the build jumps up by 14.5 MB:
$ GOOS=linux GOARCH=amd64 ./tool/go build -tags=ts_include_cli,ts_omit_webclient,ts_omit_systray,ts_omit_debugeventbus -o before ./cmd/tailscaled
$ GOOS=linux GOARCH=amd64 ./tool/go build -tags=ts_include_cli,ts_omit_webclient,ts_omit_systray,ts_omit_debugeventbus,ts_debug_forcereflect -o after ./cmd/tailscaled
$ ls -l before after
-rwxr-xr-x@ 1 bradfitz staff 41011861 Sep 9 07:28 before
-rwxr-xr-x@ 1 bradfitz staff 55610948 Sep 9 07:29 after
This is particularly pronounced with large deps like the AWS SDK. If you compare using ts_omit_aws:
-rwxr-xr-x@ 1 bradfitz staff 38284771 Sep 9 07:40 no-aws-no-reflect
-rwxr-xr-x@ 1 bradfitz staff 45546491 Sep 9 07:41 no-aws-with-reflect
That means adding AWS to a non-reflect binary adds 2.7 MB but adding
AWS to a reflect binary adds 10 MB.

We should never use the real syspolicy implementation in tests by
default. (the machine's configuration shouldn't affect tests)
You either specify a test policy, or you get a no-op one.

state secret not existing. During other parts of the boot process we
gracefully handle the state secret not being created yet, but missed
that check within `resetContainerbootState`

Fix "file not found" errors when WebDAV clients access files/dirs inside
directories with spaces.
The issue occurred because StatCache was mixing URL-escaped and
unescaped paths, causing cache key mismatches.
Specifically, StatCache.set() parsed WebDAV responses containing
URL-escaped paths (ex. "Dir%20Space/file1.txt") and stored them
alongside unescaped cache keys (ex. "Dir Space/file1.txt").
This mismatch prevented StatCache.get() from correctly determining whether
a child file existed.
See https://github.com/tailscale/tailscale/issues/13632#issuecomment-3243522449
for the full explanation of the issue.
The decision to keep all paths references unescaped inside the StatCache
is consistent with net/http.Request.URL.Path and rewrite.go (sole consumer)
Update unit test to detect this directory space mishandling.

Before:
$ tailscale ip -4
1.2.3.4
$ tailscale set --exit-node=1.2.3.4
no node found in netmap with IP 1.2.3.4
After:
$ tailscale set --exit-node=1.2.3.4
cannot use 1.2.3.4 as an exit node as it is a local IP address to this machine; did you mean --advertise-exit-node?
The new error message already existed in the code, but would only be
triggered if the backend wasn't running -- which means, in practice,
it would almost never be triggered.
The old error message is technically true, but could be confusing if you
don't know the distinction between "netmap" and "tailnet" -- it could
sound like the exit node isn't part of your tailnet. A node is never in
its own netmap, but it is part of your tailnet.
This error confused me when I was doing some local dev work, and it's
confused customers before (e.g. #7513). Using the more specific error
message should reduce confusion.

Now that we have policytest and the policyclient.Client interface, we
can de-global-ify many of the tests, letting them run concurrently
with each other, and just removing global variable complexity.
This does ~half of the LocalBackend ones.

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).

Previously, when attempting a risky action, the CLI printed a 5 second countdown saying
"Continuing in 5 seconds...". When the countdown finished, the CLI aborted rather than
continuing.
To avoid confusion, but also avoid accidentally continuing if someone (or an automated
process) fails to manually abort within the countdown, we now explicitly prompt for a
y/n response on whether or not to continue.
