Logging in goroutines after the test completed
caused data races and panics. Prevent that.

Brad Fitzpatrick d5405c66b7 net/tsdial: start of new package to unify all outbound dialing complexity
For now this just deletes the net/socks5/tssocks implementation (and
the DNSMap stuff from wgengine/netstack) and moves it into net/tsdial.

Then initialize a Dialer early in tailscaled, currently only use for the
outbound and SOCKS5 proxies. It will be plumbed more later. Notably, it
needs to get down into the DNS forwarder for exit node DNS forwading
in netstack mode. But it will also absorb all the peerapi setsockopt
and netns Dial and tlsdial complexity too.

Updates #1713

Josh Bleecher Snyder deb2f5e793 types/logger: add Context and related helpers
We often need both a log function and a context.
We can do this by adding the log function as a context value.
This commit adds helper glue to make that easy.
It is designed to allow incremental adoption.

Josh Bleecher Snyder e16cb523aa net/nettest: deflake TestPipeTimeout
The block-write and block-read tests are both flaky,
because each assumes it can get a normal read/write
completed within 10ms. This isn’t always true.

We can’t increase the timeouts, because that slows down the test.
However, we don’t need to issue a regular read/write for this test.
The immediately preceding tests already test this code,
using a far more generous timeout.

Remove the extraneous read/write.

This drops the failure rate from 1 per 20,000 to undetectable
on my machine.

While we’re here, fix a typo in a debug print statement.

It's a basic "deny everything" policy, since DERP's HTTP

Josh Bleecher Snyder 73beaaf360 net/tstun: rate limit "self disco out packet" logging
When this happens, it is incredibly noisy in the logs.
It accounts for about a third of all remaining
"unexpected" log lines from a recent investigation.

It's not clear that we know how to fix this,
we have a functioning workaround,
and we now have a (cheap and efficient) metric for this
that we can use for measurements.

So reduce the logging to approximately once per minute.
