Add TCP polling mechanism in KeepaliveTracker to understand if
there are any TCP sockets in the target network. This is a
preparation commit for dynamically control keepalive based on
the existence of TCP sockets. This is non-functional now since
there is no caller to retrieve the information now.

Instead of using a separate service-mdns library, move the code to
service-connectivity-t.
service-connectivity-t is chosen because it has access to hidden API of
classes that were made updatable in T, such as NsdServiceInfo and

Add MdnsMultinetworkSocketClient which is using for managing
multinetwork for discovery and resolution. If the requests are
specified the network to do the discovery or resolution, it
should send the queries and receive the responses on the active

This commit exposes APIs to migrate a tunnel mode transform to
new source/destination addresses, as required by MOBIKE.
By calling the exposed API, the caller only caches the new
address in the transform. To complete the migration, caller
MUST apply the tranform to the appropriate tunnel.
This API design is mainly based on the kernel interface and use
cases. The Linux kernel requires Android to provide both the
IpSecTransform and the IpSecTunnelInterface to perform the
migration. And in most cases those two instances are managed
by different entities: IpSecTranform is managed by the key
exchange protocol (e.g. IKE) and IpSecTunnelInterface is managed by
the security tunnel provider (e.g. VPN, VCN, and IWLAN). Thus the
migration process has been designed to have two steps where the
key exchange protocol negotiates and caches the new address,
passes out the updated transform, and the security tunnel
provider applies the transform to a tunnel.
Another benefit of this API is it can also apply to the case
where the network peer does not support MOBIKE and thus cannot
update the existing transforms. In this case, the key exchange
protocol can create a new transform and give it to the security
tunnel provider, and the tunnel provider can still call "apply"
to perform migration without needing to know the details of the
transform update process.

MdnsAdvertiser takes requests to advertise services on given Networks,
and relays them to internal maps of MdnsInterfaceAdvertisers.
SocketProvider is used to create the sockets for the requested networks.
It also ensures that added services do not have name conflicts, as
registration of one service should use the same name on all interfaces,
so any conflict means that every MdnsInterfaceAdvertiser needs to use a
different name. Names are automatically updated with a number suffix
(like "service (2)", "service (3)"), similarly to the legacy
mdnsresponder implementation.
The implementatio of MdnsInterfaceAdvertiser will be added in a
different change.

In the original design that using qtaguid module to get the
stats, mDevRecorder was for interface-level summary which
may include non IP layer traffic and mXtRecorder was for
interface-level summary which is only IP layer traffic.
It's migrated to use xt_bpf to read ifaces stats currently
since the qtaguid proc file is no longer exist. Both
readNetworkStatsSummaryXt() and readNetworkStatsSummaryDev()
return stats from bpf iface stats map. mDevRecorder has the
same content as mXtRecorder, and there's no usage actually
reference to mDevRecorder. Thus mDevRecorder can be removed.

NetworkTemplate was moved into mainline module and
provide Builder for external users to build template.
MATCH_MOBILE_WILDCARD and MATCH_WIFI_WILDCARD are not
exposed so currently the usage of these two constants

After removing the constants, two methods matchesWifi

The previous implementation of writeLabels would not include a
compressed name in the label dictionary, so if a packet had
"something.local", "a.service.local" and "b.service.local",
"service.local" would not be compressed because "a.service.local"
already used compression (for .local).
