this appears to work, most of the time.
there's lots of documentation work remaining,
thinking through the structure remaining,
testing remaining,
porting to file remaining (if appropriate).
Well that's an interesting one!
Apparently if you issue multiple concurrent preadv calls on
a TUN device using io_uring, the TUN device falls over.
Possibly corrupting memory along the way.
Which might be why the kernel hung on shutdown...
avoids a per-packet alloc
i will atone for my sins later
if only C let you return multiple values.
or Go let you pass in a pointer w/o it being on the heap.
This does a few things:
1. Rewrites the tests so that we get a log of what individual tests
failed at the end of a test run.
2. Adds a test that runs an HTTP server via the tester tailscale node and
then has the VMs connect to that over Tailscale.
3. Dials the VM over Tailscale and ensures it answers SSH requests.
4. Other minor framework refactoring.

Oracle Linux[1] is a CentOS fork. It is not very special. I am adding it
to the integration jungle because I am adding it to pkgs and the website
directions.

To remove some multi-case selects, we intentionally allowed
sends on closed channels (cc23049cd2).
However, we also introduced concurrent sends and closes,
which is a data race.
This commit fixes the data race. The mutexes here are uncontended,
and thus very cheap.

It was caching too aggressively, as it didn't see our deps due to our
running "go install tailscaled" as a child process.
