Josh Bleecher Snyder de635ac0a8 cmd/tailscale: print more detail in connection failure error message
Before:

failed to connect to local tailscaled (which appears to be running). Got error: Get "http://local-tailscaled.sock/localapi/v0/status": EOF

After:

failed to connect to local tailscaled (which appears to be running as IPNExtension, pid 2118). Got error: Get "http://local-tailscaled.sock/localapi/v0/status": EOF

This was useful just now, as it made it clear that tailscaled I thought
I was connecting to might not in fact be running; there was
a second tailscaled running that made the error message slightly misleading.

Brad Fitzpatrick adc5997592 net/tsdial: give netstack a Dialer, start refactoring name resolution
This starts to refactor tsdial.Dialer's name resolution to have
different stages: in-memory MagicDNS vs system resolution. A future
change will plug in ExitDNS resolution.

This also plumbs a Dialer into netstack and unexports the dnsMap
internals.

And it removes some of the async AddNetworkMapCallback usage and
replaces it with synchronous updates of the Dialer's netmap
from LocalBackend, since the LocalBackend has the Dialer too.

Brad Fitzpatrick c37af58ea4 net/tsdial: move more weirdo dialing into new tsdial package, plumb
Not done yet, but this move more of the outbound dial special casing
from random packages into tsdial, which aspires to be the one unified
place for all outbound dialing shenanigans.

Then this plumbs it all around, so everybody is ultimately
holding on to the same dialer.

As of this commit, macOS/iOS using an exit node should be able to
reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt
to stay within the Network Extension.

A number of steps remain, including but limited to:

* move a bunch more random dialing stuff

* make netstack-mode tailscaled be able to use exit node's DNS proxy,
  teaching tsdial's resolver to use it when an exit node is in use.

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.

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.
