julianknodt fb06ad19e7 wgcfg: Switch to using mem.RO
As Brad suggested, mem.RO allows for a lot of easy perf gains. There were also some smaller
changes outside of mem.RO, such as using hex.Decode instead of hex.DecodeString.

julianknodt 664edbe566 wgcfg: add benchmark for FromUAPI
Adds a benchmark for FromUAPI in wgcfg.
It appears that it's not actually that slow, the main allocations are from the scanner and new
config.
Updates #1912.

tstest/integration/vms: split up test framework into files (#2396)
My spatial memory functions poorly with large files and the vms_test.go
file recently surpassed the point where it functions adequately. This
patch splits up vms_test.go into more files to make my spatial memory
function like I need it to.

tstest/integration/vms: unbreak nixos builds (#2372)
To avoid the generated nixos disk images from becoming immune from the
GC, I delete the symlink to the nix store at the end of tests.
`t.Cleanup` runs at the end of a test. I changed this part of the code
to have a separate timer for how long it takes to run NixOS builds, but
I did that by using a subtest. This means that it was creating the NixOS
image, deleting its symlink and then trying to use that symlink to find
the resulting disk image, making the whole thing ineffectual.

This was a mistake. I am reverting this change made in
https://github.com/tailscale/tailscale/pull/2360 to remove this layer of
subtesting.

tstest/integration/vms: end-to-end UDP test (#2361)
This tests incoming and outgoing UDP traffic. It would test incoming UDP
traffic however our socks server doesn't seem to allow for connecting to
destinations over UDP. When the socks server gets that support the
incoming test should pass without issue.

tstest/integration/vms: outgoing SSH test (#2349)
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.

Josh Bleecher Snyder 0ad92b89a6 net/tstun: fix data races
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.
