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
NsdManager. mdns code can be there as it is only loaded on T+.

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
networks only. This can save the resource by reducing unnecessary
queries and align the behavior with mdnsresponder.

PacketRepeater can just try to send to both v4 and v6 multicast
addresses, and rely on MdnsReplySender to check whether the sockets have
(automatically) joined the v4 or v6 groups, so there is no need to use

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.

as the only preferred network for specific apps.

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).
Fix this and add a test.

Although RFC3845 2.1.1 specifies that NSEC records should not use
compression for the Next DomainName field, RFC6762 18.14 specifies that

In Nsd, every request has Network info to assign the specific
network to do the mdns query. But the response MdnsServiceInfo
only has interface index which is not very useful and need to
transfer to a Network every time when using it because most
APIs for apps to use the network are based on Network object.
Thus, put the Network info into MdnsServiceInfo.
