Brad Fitzpatrick 01185e436f types/result, util/lineiter: add package for a result type, use it
This adds a new generic result type (motivated by golang/go#70084) to
try it out, and uses it in the new lineutil package (replacing the old
lineread package), changing that package to return iterators:
sometimes over []byte (when the input is all in memory), but sometimes
iterators over results of []byte, if errors might happen at runtime.

Nick Khyl 2a2228f97b util/syspolicy/setting: make setting.RawItem JSON-marshallable
We add setting.RawValue, a new type that facilitates unmarshalling JSON numbers and arrays
as uint64 and []string (instead of float64 and []any) for policy setting values.
We then use it to make setting.RawItem JSON-marshallable and update the tests.

Nick Hill 9a73462ea4 types/lazy: add DeferredInit type
It is sometimes necessary to defer initialization steps until the first actual usage
or until certain prerequisites have been met. For example, policy setting and
policy source registration should not occur during package initialization.
Instead, they should be deferred until the syspolicy package is actually used.
Additionally, any errors should be properly handled and reported, rather than
causing a panic within the package's init function.

In this PR, we add DeferredInit, to facilitate the registration and invocation
of deferred initialization functions.

Nick Khyl af3d3c433b types/prefs: add a package containing generic preference types
This adds a new package containing generic types to be used for defining preference hierarchies.
These include prefs.Item, prefs.List, prefs.StructList, and prefs.StructMap. Each of these types
represents a configurable preference, holding the preference's state, value, and metadata.
The metadata includes the default value (if it differs from the zero value of the Go type)
and flags indicating whether a preference is managed via syspolicy or is hidden/read-only for
another reason. This information can be marshaled and sent to the GUI, CLI and web clients
as a source of truth regarding preference configuration, management, and visibility/mutability states.

We plan to use these types to define device preferences, such as the updater preferences,
the permission mode to be used on Windows with #tailscale/corp#18342, and certain global options
that are currently exposed as tailscaled flags. We also aim to eventually use these types for
profile-local preferences in ipn.Prefs and and as a replacement for ipn.MaskedPrefs.

The generic preference types are compatible with the tailscale.com/cmd/viewer and
tailscale.com/cmd/cloner utilities.

a container type should also implement and export a ContainerView[T, V] type
and a ContainerViewOf(*Container[T]) ContainerView[T, V] function, which
returns a view for the specified container, inferring the element view type V
from the element type T.

Brad Fitzpatrick 86e0f9b912 net/ipset, wgengine/filter/filtertype: add split-out packages
This moves NewContainsIPFunc from tsaddr to new ipset package.

And wgengine/filter types gets split into wgengine/filter/filtertype,
so netmap (and thus the CLI, etc) doesn't need to bring in ipset,
bart, etc.

Then add a test making sure the CLI deps don't regress.

Brad Fitzpatrick 964282d34f ipn,wgengine: remove vestigial Prefs.AllowSingleHosts
It was requested by the first customer 4-5 years ago and only used
for a brief moment of time. We later added netmap visibility trimming
which removes the need for this.

It's been hidden by the CLI for quite some time and never documented
anywhere else.

This keeps the CLI flag, though, out of caution. It just returns an
error if it's set to anything but true (its default).

Brad Fitzpatrick 8444937c89 control/controlclient: fix panic regression from earlier load balancer hint header
In the recent 20e9f3369 we made HealthChangeRequest machine requests
include a NodeKey, as it was the oddball machine request that didn't
include one. Unfortunately, that code was sometimes being called (at
least in some of our integration tests) without a node key due to its
registration with health.RegisterWatcher(direct.ReportHealthChange).

Fortunately tests in corp caught this before we cut a release. It's
possible this only affects this particular integration test's
environment, but still worth fixing.

wgengine/magicsock: implement probing of UDP path lifetime (#10844)
This commit implements probing of UDP path lifetime on the tail end of
an active direct connection. Probing configuration has two parts -
Cliffs, which are various timeout cliffs of interest, and
CycleCanStartEvery, which limits how often a probing cycle can start,
per-endpoint. Initially a statically defined default configuration will
be used. The default configuration has cliffs of 10s, 30s, and 60s,
with a CycleCanStartEvery of 24h. Probing results are communicated via
clientmetric counters. Probing is off by default, and can be enabled
via control knob. Probing is purely informational and does not yet
drive any magicsock behaviors.

This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled
clients can use this value to disambiguate fast user switching from one tailnet

this information during backend starts and profile switches so that users don't
have to re-authenticate their profile. The first client to use this new
information is the CLI in 'tailscale switch -list' which now uses text/tabwriter
to display the ID, Tailnet, and Account. Since account names are ambiguous, we
allow the user to pass 'tailscale switch ID' to specify the exact tailnet they
want to switch to.
