This change ensures that app data accounting works correctly within the
confines of in-kernel dataplanes, as used by platform VPNs and the VCN.
Notably, the VCN MUST NOT specify the IMSI, as that would lead to double
counting of the interface statistics.

Starting with API level 31, the subscriberId is applicable
for the wifi network. Considering applications may use
null or an empty string as subscriberId (for instance, cts),
frameworks create MATCH_WIFI_WILDCARD NetworkTemplate when querying
wifi network with null or an empty string which is the behavior before
API level 31.

Currently, NsdService starts the native mdnsresponder daemon if any
NsdManager connect to it, which results in that when any constant
service holds the NsdManager connection, the device would always be
in the mdns multicast group whatever the connection is not used or not.
This is because mdnsresponder will join the multicast group when it
starts.
To solve this problem, start the native daemon only when needed, and
clean it up after the given idle timeout.
1. Start the native daemon when a new request come.
2. If there is no pending request, clean up the daemon after 3 seconds
of idle time.

The carrier network means any network which linked with sepcific
subscriberId (for instances: merged Wifi or mobile).
Update default policy to use carrier network template to replace mobile
template.
No impact for current AOSP user because no any wifi network is merged
wifi. (Because the merged wifi network requires to support from the wifi module).
Also this change convert all of the old policies which template is

This CL modifies NetworkTemplate#buildTemplateCarrier to force on
metered carrier network and rename to buildTemplateCarrierMetered.
This method was introduced recently and has no callers.
This method will be used in Settings and NetworkPolicyManagerService
to display and manage data usage on carrier metered networks.
Settings/NetworkPolicyManagerService will use it instead of the existing
method buildTemplateMobileAll method, which only matches metered networks.
That code will change from matching metered mobile networks to matching
metered carrier networks.
Note: The carrier metered network includes metered mobile network and
metered "merged carrier wifi network" that is a specific cerrier wifi network
which provides the same user experience as mobile.

This change adds support for IPsec forward policies, which are necessary
for packets to be allowed to be forwarded to another interface, as is
the case with tethering. This is necessary and useful only within the
system server, and as such is not exposed as a public API.
This change is safe, since the addition of a FWD policy on IPsec tunnel
interfaces will by default block forwarded traffic (as would be the case
without this patch). In the event that the (system) owner of the tunnel
requires support for forwarded packets (eg tethering), this patch allows
application of transforms in the FWD direction as well.
This will be used to ensure that the VCN can be used as the underlying
network for the purposes of tethering.

Carrier merged wifi network is a specific cerrier wifi network
which provides the same user experience as mobile.
To support data usage accounting for carrier merged wifi,
the change provide several APIs in NetworkTemplate:
1. extend buildTemplateWifi so it could be used for matching
wifi networks with subscriber Id (IMSI).
2. add buildTemplateCarrier to let
NetworkPolicyManagerService creates a single policy for
a given carrier regardless of network type.

(cherry-picked from ag/13959436)
Rename StringNetworkSpecifier to EthernetNetworkSpecifier (its only
production user), and make it module-lib API.
The original StringNetworkSpecifier file is actually kept to satisfy
some invalid dependencies; it will be removed separately.
This allows specifying an Ethernet interface with a non-deprecated API:
until this change the only way to do so would be to use
NetworkRequest#setSpecifier(String), which is deprecated.
Similarly, add the TestNetworkSpecifier API for TestNetworkManager, to
replace previous usage of StringNetworkSpecifier. TestNetworkManager is
module API, so TestNetworkSpecifier should be module API too. This
allows tests to request the test interface specifically, without using
the deprecated NetworkRequest#setSpecifier(String).

This reverts commit 272ee7c909.
Reason for revert:
1. The BUILD_VERSIONS.S is 1000, and thus it will prevent
the code from requiring new algorithms on devices whose
first sdk is 31 (e.g. cuttlefish), though these devices
should be treated as first launched with SDK S.
2. It will break #testValidationForAlgosAddedInS, because
the test code is using BUILD_VERSIONS.R to gate the test,
which is inconsistent with the implementation.

not ideal to expose as system API since the plan is to get rid

it has @UnsupportedAppUsage annotation.
