Tests are sometimes run on hardware devices with wrongly configured wifi
or cell data. Ensure that this is reported as an infra error, and not a
test error, so the root cause is easier to identify.

After this change, all synchronous state machine functions are
implemented.
There are some intentional limiations:
1. Allow setup states before machine thread started or inside machine
   thread but states can only be setup once before calling #start.
2. The behavior of transitionTo is defined so that the destination
   state can never change during state transitions. Once a destination
   has been specified, it cannot be changed until the previous state
   transition is complete. In other words, SyncStateMachine does not
   support calling transitionTo in State enter or exit.
3. Support sendSelfMessage in State#processMessage(), #enter() and
   #exit(). This allow automaton to decide the follow up action by
   itself. For example: if something wrong happens during state
   transition, the implementation can enqueue an error message then
   process the error message after finishing the current state
   transition.

Implement performTransitions which does state transitions.
1. Determine the common ancestor state of current/destination states
2. Invoke state exit list from current state to common ancestor state.
3. Invoke state enter list from common ancestor state to destState by
going through mEnterStateStack.

The state transition is always defined so that the target can never be
changed mid-way of a state transition. In other words, calling
transitionTo in State enter and exit is not allowed.

Found R8 accidentally remove TetheringUtils jni methods while doing
some refactor. If any of jni java methods is removed by R8, devices
would fail to boot because of jni registering failure. Explicitly
adding progurad rule to make sure R8 never remove it.

Test that when a responder only responds with the exact records that
were queried, so only reply for PTR in discovery, only send SRV, TXT,
A, AAAA when asked explicitly, service resolve succeeds.

This ensures that the querier sends followup queries for each record.
See RFC6763 12., especially the last paragraph.

This is based on network driver populated skb->mark magic bit.
This is the bit used by netd's WakeupController.

We mandated the location of this bit in U, though we haven't
(yet??) mandated it being supported by all network drivers.

If the driver doesn't support it, it could always
be false (skb->mark should default to 0),
or potentially (this is very very unlikely) be garbage.

IFIRC nettrace isn't enabled on pre-U devices anyway.

The test flake is likely caused by a carrier configuration
update. After the update is complete, the shell permission is
dropped, which causes the test network setup to fail due to a
lack of permission. The test network setup should also be
protected by a synchronized lock to avoid permission lost.
