The encoding/json/v2 effort may end up changing
the default represention of time.Duration in JSON.
See https://go.dev/issue/71631
The GoDuration type allows us to explicitly use
the time.Duration.String representation regardless of
whether we serialize with v1 or v2 of encoding/json.

QNAP now requires builds to be signed with an HSM.
This removes support for signing with a local keypair.
This adds support for signing with a Google Cloud hosted key.
The key should be an RSA key with protection level `HSM` and that uses PSS padding and a SHA256 digest.
The GCloud project, keyring and key name are passed in as command-line arguments.
The GCloud credentials and the PEM signing certificate are passed in as Base64-encoded command-line arguments.

This adds a feature/taildrop package, a ts_omit_taildrop build tag,
and starts moving code to feature/taildrop. In some cases, code
remains where it was but is now behind a build tag. Future changes
will move code to an extension and out of LocalBackend, etc.

When an event bus is plumbed in, use it to subscribe and react to port mapping
updates instead of using the client's callback mechanism. For now, the callback
remains available as a fallback when an event bus is not provided.

When an event bus is configured publish an event each time a new port mapping
is updated. Publication is unconditional and occurs prior to calling any
callback that is registered. For now, the callback is still fired in a separate
goroutine as before -- later, those callbacks should become subscriptions to
the published event.
For now, the event type is defined as a new type here in the package. We will
want to move it to a more central package when there are subscribers. The event
wrapper is effectively a subset of the data exported by the internal mapping
interface, but on a concrete struct so the bus plumbing can inspect it.

In preparation for adding more parameters (and later, moving some away), rework
the portmapper constructor to accept its arguments on a Config struct rather
than positionally.
This is a breaking change to the function signature, but one that is very easy
to update, and a search of GitHub reveals only six instances of usage outside
clones and forks of Tailscale itself, that are not direct copies of the code
fixed up here.
While we could stub in another constructor, I think it is safe to let those
folks do the update in-place, since their usage is already affected by other
changes we can't test for anyway.

This feature is "registered" as an ipnlocal.Extension, and
conditionally linked depending on GOOS and ts_omit_relayserver build
tag.
The feature is not linked on iOS in attempt to limit the impact to
binary size and resulting effect of pushing up against NetworkExtension
limits. Eventually we will want to support the relay server on iOS,
specifically on the Apple TV. Apple TVs are well-fitted to act as
underlay relay servers as they are effectively always-on servers.
This skeleton begins to tie a PeerAPI endpoint to a net/udprelay.Server.
The PeerAPI endpoint is currently no-op as
extension.shouldRunRelayServer() always returns false. Follow-up commits
will implement extension.shouldRunRelayServer().

https://github.com/tailscale/tailscale/pull/15395 changed the logic to
skip `EditPrefs` when the platform doesn't support auto-updates. But the
old logic would only fail `EditPrefs` if the auto-update value was
`true`. If it was `false`, `EditPrefs` would succeed and store `false`
in prefs. The new logic will keep the value `unset` even if the tailnet
default is `false`.

In this PR, we enable extensions to track changes in the current prefs. These changes can result from a profile switch
or from the user or system modifying the current profile’s prefs. Since some extensions may want to distinguish between
the two events, while others may treat them similarly, we rename the existing profile-change callback to become
a profile-state-change callback and invoke it whenever the current profile or its preferences change. Extensions can still
use the sameNode parameter to distinguish between situations where the profile information, including its preferences,
has been updated but still represents the same tailnet node, and situations where a switch to a different profile has been made.
Having dedicated prefs-change callbacks is being considered, but currently seems redundant. A single profile-state-change callback
is easier to maintain. We’ll revisit the idea of adding a separate callback as we progress on extracting existing features from LocalBackend,
but the conversion to a profile-state-change callback is intended to be permanent.
Finally, we let extensions retrieve the current prefs or profile state (profile info + prefs) at any time using the new
CurrentProfileState and CurrentPrefs methods. We also simplify the NewControlClientCallback signature to exclude
profile prefs. It’s optional, and extensions can retrieve the current prefs themselves if needed.

[G,S]etWindowLongPtrW are not available on 32-bit Windows, where [G,S]etWindowLongW should be used instead.
The initial revision of #14945 imported the win package for calling and other Win32 API functions, which exported
the correct API depending on the platform. However, the same logic wasn't implemented when we removed
the win package dependency in a later revision, resulting in panics on Windows 10 x86 (there's no 32-bit Windows 11).
In this PR, we update the ipn/desktop package to use either [G,S]etWindowLongPtrW or [G,S]etWindowLongW
depending on the platform.

On darwin, os.Hostname is no longer reliable when called
from a sandboxed process. To fix this, we will allow clients
to set an optional callback to query the hostname via an
alternative native API.
We will leave the default implementation as os.Hostname since
this works perfectly well for almost everything besides sandboxed
darwin clients.

In this PR, we add two methods to facilitate extension lookup by both extensions,
and non-extensions (e.g., PeerAPI or LocalAPI handlers):
- FindExtensionByName returns an extension with the specified name.
It can then be type asserted to a given type.
- FindMatchingExtension is like errors.As, but for extensions.
It returns the first extension that matches the target type (either a specific extension
or an interface).

In this PR, we refactor the LocalBackend extension system, moving from direct callbacks to a more organized extension host model.
Specifically, we:
- Extract interface and callback types used by packages extending LocalBackend functionality into a new ipn/ipnext package.
- Define ipnext.Host as a new interface that bridges extensions with LocalBackend.
It enables extensions to register callbacks and interact with LocalBackend in a concurrency-safe, well-defined, and controlled way.
- Move existing callback registration and invocation code from ipnlocal.LocalBackend into a new type called ipnlocal.ExtensionHost,
implementing ipnext.Host.
- Improve docs for existing types and methods while adding docs for the new interfaces.
- Add test coverage for both the extracted and the new code.
- Remove ipn/desktop.SessionManager from tsd.System since ipn/desktop is now self-contained.
- Update existing extensions (e.g., ipn/auditlog and ipn/desktop) to use the new interfaces where appropriate.
We're not introducing new callback and hook types (e.g., for ipn.Prefs changes) just yet, nor are we enhancing current callbacks,
such as by improving conflict resolution when more than one extension tries to influence profile selection via a background profile resolver.
These further improvements will be submitted separately.

Ultimately, we'd like to get rid of the concept of the "current user". It is only used on Windows,
but even then it doesn't work well in multi-user and enterprise/managed Windows environments.
In this PR, we update LocalBackend and profileManager to decouple them a bit more from this obsolete concept.
This is done in a preparation for extracting ipnlocal.Extension-related interfaces and types, and using them
to implement optional features like tailscale/corp#27645, instead of continuing growing the core ipnlocal logic.
Notably, we rename (*profileManager).SetCurrentUserAndProfile() to SwitchToProfile() and change its signature
to accept an ipn.LoginProfileView instead of an ipn.ProfileID and ipn.WindowsUserID. Since we're not removing
the "current user" completely just yet, the method sets the current user to the owner of the target profile.
We also update the profileResolver callback type, which is typically implemented by LocalBackend extensions,
to return an ipn.LoginProfileView instead of ipn.ProfileID and ipn.WindowsUserID.

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.
