Allow stop TETHERING_NCM no matter ncm is used for TETHERING_USB or
TETHERING_NCM.
Add a test:
1. NCM is started for TETHERING_NCM
2. The config changes to use NCM for TETHERING_USB.
3. Then the config changes to use RNDIS for TETHERING_USB.
Also let some logs not only print in dumpsys, but also in logcat to
easiler debug unit test.

This is supported by:
1. Utilize the new API from both NetworkStatsProvider
and IOffloadControl to send data warning quota to hardware.
And pass the warning reached notification back to NPMS.
2. Disable software solution introduced in R release for
V1.1+ hardware, since now we can fully offload data warning
and limit notification to hardware.

This is a no-op change that just adapt new API from
NetworkStatsProvider to get warning and limit bytes at the same

patches to set warning bytes to hardware.

This is a no-op change that redirect both V1.0 and V1.1 callback
events to the same handling function. Since the V1.1 callback
is extended from V1.0 callback, we can safely use V1.1
callback for both V1.0 and V1.1 control.
The change also provides interface for subsequent
OffloadController changes to set warning and limit at the
same time.

To avoid log flooding, suppress CMD_IPV6_TETHER_UPDATE and
CMD_NEIGHBOR_EVENT message log because they appear frequentlg and
don't have any content which means they are ueseless for debugging.

Currently, when a network that uses 464xlat is torn down,
NetworkCallbacks will receive onLinkPropertiesChanged after
onLost. This is confusing and incorrect.
The incorrect callback is sent because handleLinkProperties
checks that the netId of the agent still exists, not that the
NetworkAgent is still registered. This is normally correct,
because the NetworkAgent is removed from mNetworkAgentInfos and
the netId are removed from mNetworkForNetId by the same method,
disconnectAndDestroyNetwork.
In this specific case it's not correct, because the call to
handleUpdateLinkProperties is from disconnectAndDestroyNetwork
itself via nai.clatd.update and calls Nat464Xlat#stop.
No other callers of handleUpdateLinkProperties are affected
because:
- EVENT_NETWORK_PROPERTIES_CHANGED is called only by
maybeHandleNetworkAgentMessage, which first checks that the
NetworkAgent is registered.
- handlePrivateDnsSettingsChanged only looks at registered
NetworkAgents (it loops over mNetworkAgentInfos).
- handlePrivateDnsValidationUpdate, handleNat64PrefixEvent and
handleCapportApiDataUpdate call getNetworkAgentInfoForNetId,
which will correctly determine that the agent is no longer
registered, since they run on the handler thread and thus
cannot run at the same time as disconnectAndDestroyNetwork.
The existing code contains a check for the netId being current.
This is intended to ensure that an update from a NetworkAgent
cannot affect another agent with the same Network. This extra
check is not necessary, because code running on the handler
thread can never observe a NetworkAgent in mNetworkAgentInfos
unless mNetworkForNetId maps that NetworkAgent's Network to that
NetworkAgent. This is because mNetworkForNetId is updated by the
same methods as mNetworkAgentInfos, and those updates occur on
the handler thread. So all code on the handler thread will see
those two as consistent.
