Although, at the moment, we do not yet require an event bus to be present, as
we start to add more pieces we will want to ensure it is always available. Add
a new constructor and replace existing uses of new(tsd.System) throughout.
Update generated files for import changes.

When compiled into TailscaleKit.framework (via the libtailscale
repository), os.Executable() returns an error instead of the name of the
executable. This commit adds another branch to the switch statement that
enumerates platforms which behave in this manner, and defaults to
"tsnet" in the same manner as those other platforms.
Fixes#15410.

Even after we remove the deprecated API, we will want to maintain a minimal
API for internal use, in order to avoid importing the external
tailscale.com/client/tailscale/v2 package. This shim exposes only the necessary
parts of the deprecated API for internal use, which gains us the following:
1. It removes deprecation warnings for internal use of the API.
2. It gives us an inventory of which parts we will want to keep for internal use.

With #14843 merged, (*localapi.Handler).servePrefs() now requires a non-nil actor,
and other places may soon require it as well.
In this PR, we update localapi.NewHandler with a new required parameter for the actor.
We then update tsnet to use ipnauth.Self.
We also rearrange the code in (*ipnserver.Server).serveHTTP() to pass the actor via Handler's
constructor instead of the field.

This pulls out the Wake-on-LAN (WoL) code out into its own package
(feature/wakeonlan) that registers itself with various new hooks
around tailscaled.
Then a new build tag (ts_omit_wakeonlan) causes the package to not
even be linked in the binary.
Ohter new packages include:
* feature: to just record which features are loaded. Future:
dependencies between features.
* feature/condregister: the package with all the build tags
that tailscaled, tsnet, and the Tailscale Xcode project
extension can empty (underscore) import to load features
as a function of the defined build tags.
Future commits will move of our "ts_omit_foo" build tags into this
style.

This adds a new ListenPacket function on tsnet.Server
which acts mostly like `net.ListenPacket`.
Unlike `Server.Listen`, this requires listening on a
specific IP and does not automatically listen on both
V4 and V6 addresses of the Server when the IP is unspecified.
To test this, it also adds UDP support to tsdial.Dialer.UserDial
and plumbs it through the localapi. Then an associated test
to make sure the UDP functionality works from both sides.

This adds a new `UserLogf` field to the `Server` struct.
When set this any logs generated by Server are logged using
`UserLogf` and all spammy backend logs are logged to `Logf`.
If it `UserLogf` is unset, we default to `log.Printf` and
if `Logf` is unset we discard all the spammy logs.

Use the zstdframe package where sensible instead of plumbing
around our own zstd.Encoder just for stateless operations.
This causes logtail to have a dependency on zstd,
but that's arguably okay since zstd support is implicit
to the protocol between a client and the logging service.
Also, virtually every caller to logger.NewLogger was
manually setting up a zstd.Encoder anyways,
meaning that zstd was functionally always a dependency.

This tripped me up when I was testing something and wrote:
if conn != nil {
conn.Close()
}
In netstack mode, when an error occurred we were getting a non-nil error
and a non-nil interface that contained a nil pointer. Instead, just
return a nil interface value.

Application code can call the tsnet s.CapturePcap(filename) method
to write all packets, sent and received, to a pcap file. The cleartext
packets are written, outside the Wireguard tunnel. This is expected
to be useful for debugging.
