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.

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.

This shouldn't be necessary, but while we're continuing to figure out
the root cause, this is better than having to restart the app or switch
profiles on the command line.

Android >=14 forbids the use of netlink sockets, and in some configurations
can kill apps that try.

The regular android app constructs its own wgengine with
additional FFI shims, so this default codepath only affects
other handcrafted buids like tsnet, which do not let the
caller customize the innards of wgengine.
Android >=14 forbids the use of netlink sockets, which makes
the standard linux router fail to initialize.

Otherwise this was repeated closing control/derp connections all the time
on netmon changes. Arguably we should do this on all platforms?

Avoid the unbounded runtime during random allocation, if random
allocation fails after a first pass at random through the provided
ranges, pick the next free address by walking through the allocated set.
The new ipx utilities provide a bitset based allocation pool, good for
small to moderate ranges of IPv4 addresses as used in natc.

The source address link selection on sandboxed macOS doesn't deal
with loopback addresses correctly. This adds an explicit check to ensure
we return the loopback interface for loopback addresses instead of the
default empty interface.
Specifically, this allows the dns resolver to route queries to a loopback
IP which is a common tactic for local DNS proxies.
Tested on both macos, macsys and tailscaled. Forwarded requests to
127/8 all bound to lo0.

This commit implements an experimental UDP relay server. The UDP relay
server leverages the Disco protocol for a 3-way handshake between
client and server, along with 3 new Disco message types for said
handshake. These new Disco message types are also considered
experimental, and are not yet tied to a capver.
The server expects, and imposes, a Geneve (Generic Network
Virtualization Encapsulation) header immediately following the underlay
UDP header. Geneve protocol field values have been defined for Disco
and WireGuard. The Geneve control bit must be set for the handshake
between client and server, and unset for messages relayed between
clients through the server.

Add the golang-image-ico package, which is an incredibly small package

look quite pixelated when displayed at this size, but it's better than
nothing, and any Windows support is just a bonus anyway.
