This will allow moving LockdownVpnTracker from the connectivity
to the VPN code. This requires moderate refactoring since it's
pretty tightly coupled to both.
In this CL:
1. Add an @hide API to tell ConnectivityService that legacy
lockdown VPN is enabled. I chose not to use the existing
setVpnRequiredForUids API because that method has specific
semantics and because it will be required long term since
it's used by non-legacy VPN types.
2. Instead of updating LockdownVpnTracker inline from the
ConnectivityService handler thread, have it listen to
NetworkCallbacks. This introduces an extra thread hop, but
most of the interactions between the lockdown VPN and CS were
via NetworkAgent, which is asynchronous anyway.
3. Add code to LegacyTypeTracker to send the extra
CONNECTIVITY_ACTION broadcast for the underlying network type
that is sent after the VPN connects. In order to do this, make
Make LockdownVpnTracker specify its underlying network
(via setUnderlyingNetworks) when it connects.
4. Reimplement LockdownVpnTracker#augmentNetworkInfo based on
information that is available in ConnectivityService.
5. Remove the code in LockdownVpnTracker that counted errors.
I think this code has not worked since lollipop, because
ConnectivityService never sees NetworkInfo objects in state
FAILED. This is because ConnectivityService only hears about
NetworkInfo objects via NetworkAgents, and LegacyVpnRunner
only registers its NetworkAgent when the connection succeeds.

Use data that is already available in ConnectivityService
instead.
The behaviour of the new implementation is slightly different
from Q and R code when the permission check fails.
- The old code would throw a SecurityException if an app that
was not an active VPN called the method, and would return
INVALID_UID if the connection belonged to a UID that was not
subject to the VPN.
- The new code returns INVALID_UID in both cases.
This does not seem like a compatibility problem. The only case in
which the code throws SecurityException is if the app is not a
current VPN app, but the app already knows whether it is or not.
The docs don't mention that the method SecurityException, either.

This method allows internal components to track the system
default network. This differs from registerDefaultNetworkCallback
because that method sends callbacks for the default network for
the UID that called it. This may not be the system default
network, for example, when a VPN is up and applies to the UID.

These tests do not actually work, or at least not as designed.
What happens when they are run is that creating/connecting the
VPN throws an exception. The call to legacyRunnerReady.block()
times out after 10 seconds because the condition variable is
never opened, but the doesn't notice the timeout becasue it
doesn't check the return value of block().
There are two reasons for the VPN not coming up.
1. VpnConfig.getIntentForStatusPanel calls into PendingIntent and
ActivityManager statics, which bypass all the mocks and fail
with an appops denial. Fix this by making it a dependency.
2. The tests are broken due to the UserManager API changes
tracked in b/175883995. Fixing by adding a bit of ad-hoc code
into startLegacyVpn, with a TODO to delete it once the rest of
the UserManager setup code is fixed.
Fix these and check the return value of block(). This ensures
that if any other breakage is added the test will actually fail.
Also check that the throw route survives all the way to the
LinkProperties sent to the agent.

The score argument is going away, so there no longer
is a need to test it. It's never been used by anybody
and is actually a problem going forward.

of the testing tool anyway, rebuild expecting requests
on top of TrackRecord. This simplifies the test a
great deal, as well as (as observed in running the
tests) makes the test faster.

Instead of classifying interfaces by network type in BatteryStats,
classify them based on the transports array provided by the
NetworkAgent.
Network types are deprecated and transports should be used instead. This
change allows BatteryStats to stop depending on unstable APIs such as
isNetworkTypeMobile.
This change also updates nullability annotations in ConnectivityService
and NetworkAgentInfo to show that the NetworkCapabilities are non-null
(as provided by the network agent) when calling
noteNetworkInterfaceTransports.

Currently, when the VPN underlying network changes from a
network that is not suspended to one that is suspended (or vice
versa), some of the legacy APIs return incorrect results.
This is because the VPN's NetworkInfo can get into SUSPENDED
state even though the capabilities have the NOT_SUSPENDED
capability. This happens because the code in updateCapabilities
that checks for changes in NOT_SUSPENDED and NOT_ROAMING (which
are the capabilities that can affect the NetworkInfo state) is
only run when the capabilities change in a certain way.
Fix this by always checking for changes in these capabilities,
regardless of what else has changed.
This results in sending a lot more SUSPENDED and RESUMED
callbacks than the code sent previously. This should hopefully
not impact apps because those callback methods have never been
public API, though because they're just callbacks, it's possible
that apps found out via code inspection that the callbacks
existed and implemented them.
