Brad Fitzpatrick 82f2fdc194 control/controlclient: adjust some logging point names
The previous code read too explicitly like log.Printf("I am here1"),
log.Printf("I am here2"). It still is with this change, but prettier, and
less subject to code rearranging order.

Brad Fitzpatrick dd97111d06 backoff: update to Go style, document a bit, make 30s explicit
Also, bit of behavior change: on non-nil err but expired context,
don't reset the consecutive failure count. I don't think the old
behavior was intentional.

control/controlclient: eliminate race in loginGoal access.
This code is currently racy due to an incorrect assumption
that goal is never modified in-place, so does not require extra locking.
This change makes the assumption correct.

David Anderson 557b310e67 control/controlclient: move auto_test back to corp repo.
It can't run without corp stuff anyway, and makes it harder to
refactor the control server.

Avery Pennarun 08acb502e5 Add tstest.PanicOnLog(), and fix various problems detected by this.
If a test calls log.Printf, 'go test' horrifyingly rearranges the
output to no longer be in chronological order, which makes debugging
virtually impossible. Let's stop that from happening by making
log.Printf panic if called from any module, no matter how deep, during
tests.

This required us to change the default error handler in at least one
http.Server, as well as plumbing a bunch of logf functions around,
especially in magicsock and wgengine, but also in logtail and backoff.

To add insult to injury, 'go test' also rearranges the output when a
parent test has multiple sub-tests (all the sub-test's t.Logf is always
printed after all the parent tests t.Logf), so we need to screw around
with a special Logf that can point at the "current" t (current_t.Logf)
in some places. Probably our entire way of using subtests is wrong,
since 'go test' would probably like to run them all in parallel if you
called t.Parallel(), but it definitely can't because the're all
manipulating the shared state created by the parent test. They should
probably all be separate toplevel tests instead, with common
setup/teardown logic. But that's a job for another time.
