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

Add MdnsRecordRepository to hold ServiceRegistration records. When a
service is added, the repository generates its records, and can generate
the ProbingInfo to use to send initial probes.

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

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.

MdnsAnnouncer is a implementations of MdnsPacketRepeater, which sends a

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
compression should also be used for NSEC RDATA. The legacy mDNS

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.

Add onServiceNameDiscovered method which is used to listen the
discovery callbacks. It would be called once the service is found
even the response is incomplete. This is different from
onServiceFound which needs to receive a complete response.
onServiceNameRemoved is used for service removal if received
response is incomplete.

Having SdkLevel.isAtLeastU() as a default value of
DeviceConfigUtils.isFeatureEnabled could result confusing behavior.
For example, when flag value is pushed to only the T device and the T
device with the flag is ugraded to U, this device could disable java bpf
map while the device keeps the flag value.
This CL prevents above confusing behavior.

Now, the value in TextEntry would be a zero length byte array if
the text record response doesn't contain the value. The problem
is that the value could either be an empty string ("key="), or
there can be no value ("key"), as per rfc6763 6.4 "If there is
no '=' in a DNS-SD TXT record string, then it is a boolean
attribute, simply identified as being present, with no value.".

Currently, NET_CAPABILITY_TEMPORARILY_NOT_METERED traffic is
counted as unmetered data usage, and "mobile data usage"
settings screen shows metered data usage which means it doesn't
include TEMPORARILY_NOT_METERED traffic. However, some carriers
show TEMPORARILY_NOT_METERED data usage in customer's bill which
would be confusing if the data usage in the device shows different
results. Thus, revert the change to avoid confusing.

This commit clear the calling identity before accessing the
DeviceConfig in ConnectivityService#dump().
The calling package of DeviceConfig.getProperties() comes from
ActivityThread.currentApplication(). In ConnectivityService#dump(),
the caller is ConnectivityService. It's OK to access DeviceConfig
from ConnectivityService. The same scenario applies to an app with
proper permission accessing DeviceConfig from its own context.
However, if cts would like to verify design by calling
ConnectivityService#dump(), the calling uid will comes from the
binder but package name will stay as ConnectivityService which
is 'android'. This will result in a SecurityException says that
the package does not match the uid and failed the test.
