4068dcbab0 [IT03] Add replacement methods for network activity
Reference for NMS in ConnectivityManager should be removed for
incoming CS mainline. The API for listening network activity
should not go into NMS. As an alternative, the registry requests
should be sent to CS and handled by CS. Add necessary alternative
in IConnectivityManger first. The detail implementation will be
added in the follow up commits.

cabcbffad8 Move phone ID to extra for action provision
Previously, the phone ID was appended to the broadcast in DCT and sent
to ConnectivityManager. Instead of sending both as an action, send the
phone ID as an extra instead to make the action a protected broadcast.

2f81e75ae4 Remove hidden deprecated getActiveNetworkQuotaInfo
getActiveNetworkQuotaInfo has never been in API surface since it
was introduced. It became essentially functionless since android O,
so there should be no usage dependency upon the hidden method,
In order to support ConnectivityService mainline, remove the
useless function to prevent necessary dependency.

8516d85251 Expose TcpRepairWindow as module-lib API
Connectivity service is going to become a mainline module which
will not be able to access hidden APIs. TcpKeepaliveController
is a part of CS mainline module, it uses TcpRepairWindow to
store tcp repair window info. Thus, expose TcpRepairWindow as

ee660cfd90 Add ConnectivityManager.TYPE_PROXY to SystemApi
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.

d707e7f5ae Do not query CS in NetworkProvider constructor
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.

129c01eabf Move applying underlying caps from Vpn to ConnectivityService.
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.

1ea1cda675 Minor fixes to NetworkCapabilities#toString.
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.

New format:
... SignalStrength: -72 OwnerUid: 1000 AdminUids: [1000] SSID: ...
... Uid: 1000 RequestorUid: 1000 RequestorPkg: android ...

3a7110e160 Fix a bug where modern network agents start in UNKNOWN
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.
