Run `staticcheck` with `U1000` to find unused code. This cleans up about
a half of it. I'll do the other half separately to keep PRs manageable.

So we're staying within the netip.Addr/AddrPort consistently and
avoiding allocs/conversions to the legacy net addr types.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

This commit updates the wireguard-go dependency and implements the
necessary changes to the tun.Device and conn.Bind implementations to
support passing vectors of packets in tailscaled. This significantly
improves throughput performance on Linux.

Upstream wireguard-go decided to use errors.Is(err, net.ErrClosed)
instead of checking the error string.
It also provided an unsafe linknamed version of net.ErrClosed
for clients running Go 1.15. Switch to that.
This reduces the time required for the wgengine/magicsock tests
on my machine from ~35s back to the ~13s it was before
456cf8a376.

LANs are authoritative for their prefixes, so we should not bounce
packets back and forth to the default gateway in that case.

The new interface lets implementors more precisely distinguish
local traffic from forwarded traffic, and applies different
forwarding logic within Machines for each type. This allows
Machines to be packet forwarders, which didn't quite work
with the implementation of Inject.

The test demonstrates that magicsock can traverse two stateful
firewalls facing each other, that each require localhost to
initiate connections.

HandlePacket and Inject now receive/take Packets. This is a handy
container for the packet, and the attached Trace method can be used
to print traces from custom packet handlers that integrate nicely
with natlab's internal traces.

The firewall provides a ProcessPacket handler, and implements an
address-and-port endpoint dependent firewall that allows all
traffic to egress from the trusted interface, and only allows
inbound traffic if corresponding outbound traffic was previously
seen.

Requires a bunch of refactoring so that Networks only ever
refer to Interfaces that have been attached to them, and
Interfaces know about both their Network and Machine.

This is a prelude to adding more fields, which would otherwise
become more unnamed function params.
