Instead of setting NetworkIdentity.subscriberId only on telephony
networks, set it when provided on any network. At the moment only
telephony is expected to have a subscriberId in its NetworkState anyway,
and while there are plans for other network agents (wifi) to have a
subscriberId, it should also be set in that case.
This allows NetworkIdentity to stop depending on hidden network type
APIs to determine if the network is mobile.

This follows other TYPE_* constants like TYPE_WIFI_P2P that are
@SystemApi or public.
TYPE_PROXY has a use-case for the system to set network policies based
on proxy network templates. Although network types are deprecated, that
use-case needs to be supported and significant amounts of network
management would need to be rewritten to stop using network types.
The constant needs to be API as ConnectivityManager is planned to move
out of framework.jar, so only its formal API will be available to the
system server.

ConnectivityService may not be available in a NetworkProvider
constructor, if it is created (but still unused) before
ConnectivityService starts.
As ConnectivityManager is only necessary in
declareNetworkRequestUnfulfillable, which should not be called often,
just query ConnectivityManager at that point.
This is necessary for VcnManagementService, which is started before
ConnectivityService and creates its NetworkProvider in its constructor.
Fortunately VcnManagementService does not call
declareNetworkRequestUnfulfillable at this point.
ConnectivityManager may be migrated to classic service getters that
cache "null" when the service was not available the first time it is
queried, so no system service must query it before it starts.

Add support to ConnectivityService to track underlying networks
directly instead of through the Vpn class.
1. Communicate all information necessary to propagate underlying
network capabilities to ConnectivityService via NetworkAgent.
This includes:
a. Underlying networks:
- Add SystemApi for NetworkAgent to declare its underlying
networks to ConnectivityService, and use it in Vpn.
- Add a new declaredUnderlyingNetworks member to
NetworkAgentInfo and store the underlying networks in it.
Move propagation of underlying network capabilities to
mixInCapabilities, which is a natural place for it.
b. "Always metered" bit:
- Communicate this to ConnectivityService via the existing
NOT_METERED capability. Store it in a new declaredMetered
boolean in NetworkAgentInfo to separate it cleanly from
the NOT_METERED bit in the capabilities, which depends on
whether the underlying networks are metered or not. In
order to ensure that this is only ever changed when a NC
update is received from a NetworkAgent, define a new
processCapabilitiesFromAgent similar to the existing
processLinkPropertiesFromAgent.
2. Ensure that propagating underlying network capabilities does
not read the VPN's NetworkCapabilities. In order to do this,
ensure that all relevant information on underlying networks
and metering is sent to ConnectivityService at NetworkAgent
registration time. CS still calls Vpn#updateCapabilities when
a user is added/removed, but that is deleted in a future CL.
3. Slightly generalize propagating underlying network
capabilities because there may be other network types that
also have underlying networks that aren't VPNs (e.g., VCN).
- Introduce a new supportsUnderlyingNetworks() boolean method
in NetworkAgentInfo.
- Rename updateAllVpnsCapabilities to
propagateUnderlyingNetworkCapabilities.
This commit does not move the actual logic of calculating the
underlying capabilities out of Vpn.java. That can be done in a
subsequent change once CS stops calling getUnderlyingNetworks().
This commit also does not modify any of the other code in CS that
directly accesses VPNs' underlying networks.

1. The current code only prints the array of administrator UIDs
if it's empty. This is clearly an oversight. Print it only if
it's non-empty.
2. Only print requestor UID and package name if they are set.
This makes output shorter in the common case that they are
unset.
3. Reorder the output at the end: group all UIDs together, and
place SSID and private DNS broken bit after that.
4. Make the private DNS broken indication a single word instead
of a sentence. This saves space and makes it easier to write
regexps.

TrafficStats API are being used for querying realtime network
statistics for years. However, on certain devices, some network
traffic are produced by hardware components and not be
able to seen by kernel counters.
Thus, include statistics for those missing network traffic is
necessary. Note that the included statistics might be stale
since polling newest stats from hardware might impact system
health and not suitable for TrafficStats API use cases.

Modern network agents are supposed to have the following
lifecycle :
• Construct the agent
• Declare itself to connectivity by calling #register()
• Possibly do some setup
• Declare connected by calling #markConnected()
• Declare disconnected by calling #unregister()
Internally ConnectivityService still manages the state
with deprecated NetworkInfo, which has a lot of possible
detailed states, most of which are now unused. Internally,
the steps above translate to the states below :
• When the agent calls #register() it starts in state
CONNECTING
• When it calls #markConnected() it goes to CONNECTED
• When it calls #unregister() it goes to DISCONNECTED which
triggers the flow that disconnects it immediately
• ConnectivityService also synthesizes the SUSPENDED state
under some situations, but that's not relevant here.
The translation above is done by the NetworkAgent class,
which translates #register(), #markConnected() and
The only valid lifecyle for new agents is thus :
CONNECTING → CONNECTED → disconnect
↕ ↑
SUSPENDED ───┘
Note that in the above scheme, there is no space for the
UNKNOWN state, which is only used by legacy network agents.
However, the constructor for NetworkInfo still starts with
UNKNOWN. Ideally the constructor for NetworkInfo would set
the info to CONNECTING instead, but this would be a very
visible change in behavior affecting many apps (especially
their tests), so for backward compatibility we can't do
that.
New network agents however don't expose their NetworkInfo
to the client code, so they can just be made to start in
CONNECTING the way it was meant.
Note that this didn't really have a concrete impact beyond
printing some logs as by and large the ConnectivityService
code handles UNKNOWN and CONNECTING the same way, or more
exactly it handles transitions to CONNECTED from UNKNOWN
and CONNECTING in the same way. The exception to this is
VPNs, which are not using the new agent API yet, and the
upcoming conversion is why this fix is actually needed now.
