Currently, native networks for non-VPN networks are created only
when the NetworkAgent goes into the CONNECTED state. This is not
ideal, because until the network is connected:
- Nothing routes to the network, so no IP packets can be sent on
it (except via packet sockets).
- Many network configuration changes (e.g., routes and DNS
servers) fail to apply because the network does not exist yet.
These cause ENONET errors in the logs.
Fix this starting in U by creating the native network as soon as
the agent registers. This should not impact apps because
NetworkCallbacks are not sent until networks are connected.

From service-connectivity, NAMESPACE_TETHERING must be used, as
NAMESPACE_CONNECTIVITY is used for the NetworkStack module. Also the
isFeatureEnabled with module name must be used, otherwise the "android"
package version is queried instead of the tethering module version.
BpfNetMaps is using flag value 1 to workaround this issue.
flags in NsdService, AutomaticOnOffKeepaliveTracker, and ConnectivityFlags
were not pushed currently.
So, this change has no effect to devices.

The ConnectivityResources class is only usable with QUERY_ALL_PACKAGES
permission, so it is not generally usable in framework-connectivity. It
is also backed by the ServiceConnectivityResources APK, which is
intended as resources for service-connectivity.
Move the class to service-connectivity and update callers. CTS needs a
way to determine the supported keepalive count as it used the
resources from KeepaliveUtils as @hide API, so provide a
ConnectivityManager @hide API for testing.

This is a clean up commit to correct the javadoc of
NetworkAgent.CMD_START_SOCKET_KEEPALIVE. This event was used
between ConnectivityService/NetworkAgent, and also
ConnectivityService/KeepaliveTracker with different semantics.

so also separate the usage to different events.
Also move the event definitions together so that a new event

This includes two restriction changes of simulateDataStall:
- Allow simulation on a network that has an underlying test
network
- Allow simulation on networks created by the system server
This commit allows VCN and VPN to CTS test their abilities of
handling suspected data stall.
This commit is safe because #simulateDataStall is already protected
by two signature permissions MANAGE_TEST_NETWORKS and NETWORK_STACK,
and those permissions are granted to only preinstalled apps.

Take a Network parameter to have an one-to-one mapping between
keepalive and its underpinned network on the automatic keepalive.
Existing design could not really tell which network should the
automatic keepalive check for the TCP socket status if there are
multiple automatic keepalives enabled, e.g. Bothe IWLAN and VPN
on WiFi enable the automatic keepalive. The keepalive for IWLAN
should check if there are any TCP sockets on the IWLAN network
instead of VPN network.

The default TCP polling alarm timer is very large(2 mins).
It's expensive in the CTS to wait for a couple alarms.
The polling alarm should be deprecated soon and replace
with callback design, so add the hidden method for testing
purpose to support the short term usage until design is
replaced with callbacks.
With the hidden method, the alarm timer will decrease to
1 second for a specified time period. The TCP sockets status
could be verified every 1 second.

This patch uses the binder token represented by the callback
to communicate the identity of the AutoOnOffKeepalive through
the alarm mechanism. This is a lot more robust and easy to
understand.
Addressing this, on top of the robustness and readability
advantages, corrects three bugs.
• The |obj| in the message to CMD_MONITOR_AUTOMATIC_KEEPALIVE
is now the binder token both on the sender side and the
receiver side, while the previous code had a Network in the
sender while the receiver expected AutoOnOffKeepalive,
crashing the system server with a wrong cast.
• The intent sent in the alarm would have a yet-uninitialized
value for the slot, so it would not be possible to find the
auto keepalive when the alarm fires.
• When the slot is reassigned, the alarm continued to fire
with the same slot value, so the auto keepalive would no
longer be found after a pause/resume cycle that would
change the slot.
