bf195cd3d8 wgengine/magicsock: reduce log verbosity of discovery messages 
Don't log heartbeat pings & pongs. Track the reason for pings and then
only log the ping/pong traffic if it was for initial path discovery.

a6559a8924 wgengine/magicsock: run test DERP in mode where only disco packets allowed 
So we don't accidentally pass a NAT traversal test by having DERP pick up our slack
when we really just wanted DERP as an OOB messaging channel.

wgengine/magicsock: make time.Sleep in runDerpReader respect cancellation. 
Before this patch, the 250ms sleep would not be interrupted by context cancellation,
which would result in the goroutine sometimes lingering in tests (100ms grace period).

wgengine/magicsock: make receive from didCopy respect cancellation. 
Very rarely, cancellation occurs between a successful send on derpRecvCh
and a call to copyBuf on the receiving side.
Without this patch, this situation results in <-copyBuf blocking indefinitely.

a2267aae99 wgengine: only launch pingers for peers predating the discovery protocol

45578b47f3 tstest/natlab: refactor PacketHandler into a larger interface. 
The new interface lets implementors more precisely distinguish
local traffic from forwarded traffic, and applies different
forwarding logic within Machines for each type. This allows
Machines to be packet forwarders, which didn't quite work
with the implementation of Inject.

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.

tstun: remove buggy-looking log line. 
This log line looks buggy, even though lacking a filter is expected during bringup.
We already know if we forget to SetFilter: it breaks the magicsock test,
so no useful information is lost.

6e8f0860af ipn: add Login backend command for sign-in with token 
The StartLoginInteractive command is for delegating the sign-in flow
to a browser. The Android Gooogle Sign-In SDK inverts the flow by
giving the client ID tokens.

Add a new backend command for accepting such tokens by exposing the existing
controlclient.Client.Login support for OAuth2 tokens. Introduce a custom
TokenType to distinguish ID tokens from other OAuth2 tokens.
