Ideally the rules should be set up before onAvailable is
sent, but onLocalNetworkChanged should be sent after.

The previous code had CSLocalAgentTests#testForwardingRules
flaky because it was waiting for onAvailable and immediately
checking that the routing rules have been set up.

There are other ways to fix this flake (e.g. wait for
onLocalNetworkChange in the test or add a timeout on
the verify(netd) call) but this patch probably implements
the best production code behavior.

The profile is modified within startLegacyVpnPrivileged(), e.g.
ipsecCaCert, ipsecUserCert. This causes subsequent calls from
callers such as LockdownVpnTracker to fail.

Add a new test to ensure the VpnProfile is not modified in
startLegacyVpn.
Add testClone in VpnProfileTest.

This commit verifies that
- If VPN network preference is set when
    - Ikev2VpnRunner is created
    - Retrying VPN
    - Updating exclusion list
- If VPN network preference is cleared when
    - Exiting VPN runner
    - NOT_RECOVERABLE happens

This is a preliminary change for filtering sockets that is not

itself is a no-op change to pass the uid information to
AutomaticOnOffKeepaliveTracker.

Like NetworkScore, this object is not available on R because
of the absence of the tethering module. Therefore it needs to
be wrapped to be protected against introspection by the test
libraries.

FileDescriptor#getInt$() is a hidden API with the unsupportedApiUsage
annotation on R. Accessing it will cause a NewApi linter check error.
It should be removed from OffloadHalHidlImpl as it is only used for

This change includes:
 1. A mechanism in DevSdkIngoreRunnrer to dump thread counts
    before/after tests, and compare thread counts to detect leaks.
 2. Add an annotation @MonitorThreadLeak for test classes to
    annotate the classes which should monitor thread leaks.
 3. Annotated NetworkStatsServiceTest to apply the enforcement.

Now, every services are cached on MdnsServiceCache, so the
remaining TTL should be checked when retrieving services from
the MdnsServiceCache and have a callback to notify the
MdnsServiceTypeClient about expired services.

Currently, BatteryStatsService register netd callback and track radio
power state only for the default network.
So, battery stats are not accurate if cellular and Wi-Fi networks are
active at the same time.

aosp/2561090 updates BatteryStatsService not to register netd callback
on V+ devices.
This CL updates LegacyNetworkActivityTracker to call BatteryStats API
and update radio power state for networks including non default networks
on V+ devices.

on V+ devices, NetworkActivityTracker adds idleTimer when the network is
first connected and removes idleTimer when the network is disconnected
so that activity tracker can receive netd
onInterfaceClassActivityChanged callback for multiple networks.

Following CL adds idleTimer for multiple networks and track activities
including non default network on V+
Current LegacyNetworkActivityTracker uses transport type as an idleTimer
label but this makes it difficult to have multiple idleTimers.
So, this CL updates LegacyNetworkActivityTracker to support using netId
as an idleTimer label.
