Arch is a bit of a weirder distro, however as a side effect it is much
more of a systemd purist experience. Adding it to our test suite will
make sure that we are working in the systemd happy path.

This distro is about to be released. OpenSUSE has historically had the
least coverage for functional testing, so this may prove useful in the
future.

Instead of testing all the VMs at once when they are all ready, this
patch changes the testing logic so that the vms are tested as soon as
they register with testcontrol. Also limit the amount of VM ram used at
once with the `-ram-limit` flag. That uses a semaphore to guard resource
use.
Also document CentOS' sins.

If you set `-distro-regex` to match a subset of distros, only those
distros will be tested. Ex:
$ go test -run-vm-tests -distro-regex='opensuse'

Don't try to do heuristics on the name. Use the net/interfaces package
which we already have to do this sort of stuff.

Instead of pulling packages from pkgs.tailscale.com, we should use the
tailscale binaries that are local to this git commit. This exposes a bit
of the integration testing stack in order to copy the binaries
correctly.
This commit also bumps our version of github.com/pkg/sftp to the latest
commit.
If you run into trouble with yaml, be sure to check out the
commented-out alpine linux image complete with instructions on how to
use it.

Previously we spewed a lot of output to stdout and stderr, even when
`-v` wasn't set. This is sub-optimal for various reasons. This patch
shunts that output to test logs so it only shows up when `-v` is set.

This will spin up a few vms and then try and make them connect to a
testcontrol server.

Only minimal tailscale + tailscaled for now.
And a super minimal in-memory logcatcher.
No control ... yet.

Importing the non-main package was missing some dependencies that
"go mod tidy" would then cleanup. Also added a non-ignore build tag to
avoid other tools getting upset about importing a main package.

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.

Use tb.Cleanup to simplify both the API and the implementation.
One behavior change: When the number of goroutines shrinks, don't log.
I've never found these logs to be useful, and they frequently add noise.

If any goroutine continues to use the logger in TestLocalLogLines
after the test finishes, the test panics.
The culprit for this was wireguard-go; the previous commit fixed that.
This commit adds suspenders: When the test is done, make logging calls
into no-ops.

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.
