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.

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

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.

This is step 2 of ~4, breaking up #14720 into reviewable chunks, with
the aim to make syspolicy be a build-time configurable feature.
Step 1 was #16984.
In this second step, the util/syspolicy/policyclient package is added
with the policyclient.Client interface. This is the interface that's
always present (regardless of build tags), and is what code around the
tree uses to ask syspolicy/MDM questions.
There are two implementations of policyclient.Client for now:
1) NoPolicyClient, which only returns default values.
2) the unexported, temporary 'globalSyspolicy', which is implemented
in terms of the global functions we wish to later eliminate.
This then starts to plumb around the policyclient.Client to most callers.
Future changes will plumb it more. When the last of the global func
callers are gone, then we can unexport the global functions and make a
proper policyclient.Client type and constructor in the syspolicy
package, removing the globalSyspolicy impl out of tsd.
The final change will sprinkle build tags in a few more places and
lock it in with dependency tests to make sure the dependencies don't
later creep back in.

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.

Add a ternary flag that unless set explicitly to false keeps the
insecure behavior of TSIDP.
If the flag is false, add functionality on startup to migrate
oidc-funnel-clients.json to oauth-clients.json if it doesn’t exist.
If the flag is false, modify endpoints to behave similarly regardless
of funnel, tailnet, or localhost. They will all verify client ID & secret
when appropriate per RFC 6749. The authorize endpoint will no longer change
based on funnel status or nodeID.
Add extra tests verifying TSIDP endpoints behave as expected
with the new flag.
Safely create the redirect URL from what's passed into the
authorize endpoint.

DERP writes go via TCP and the host OS will have plenty of buffer space.
We've observed in the wild with a backed up TCP socket kernel side
buffers of >2.4MB. The DERP internal queue being larger causes an
increase in the probability that the contents of the backbuffer are
"dead letters" - packets that were assumed to be lost.
A first step to improvement is to size this queue only large enough to
avoid some of the initial connect stall problem, but not large enough
that it is contributing in a substantial way to buffer bloat /
dead-letter retention.

The suggested exit node is currently only calculated during a localAPI request.
For older UIs, this wasn't a bad choice - we could just fetch it on-demand when a menu
presented itself. For newer incarnations however, this is an always-visible field
that needs to react to changes in the suggested exit node's value.
This change recalculates the suggested exit node ID on netmap updates and
broadcasts it on the IPN bus. The localAPI version of this remains intact for the
time being.
