In some use cases for the MdnsDiscoveryManager, providing looper as an
argument to the MdnsDiscoveryManager constructor is not feasible. Adding
a constructor without looper can help to match those use cases. If
constructor without looper is used. The shutDown() must be called as a
part of cleanup process.

Packets received from the "null" networks are packets received from
tethering downstream interfaces. They should not be processed by all
MdnsServiceTypeClients; instead they should be processed by
the MdnsServiceTypeClient for the null network.

When sendMulticastPacket or sendUnicastPacket is called with the null
network, only send the packets to interfaces indexed with null, instead
of all interfaces.
When using MdnsMultinetworkSocketClient sending packets on the null
network means sending on tethered downstream interfaces. When
MdnsSocketClient is used (not used in the Android tree), sending on the
null network sends on all interfaces as MdnsSocketClient does not
support specific networks. This is clarified by explicitly throwing
when a non-null Network is attempted to be used with MdnsSocketClient
(but MdnsSocketClient is only used for tests in the Android tree).

Instead of the network specified in the MdnsSearchOptions, which is
often null to request searching on all networks, use the
MdnsServiceTypeClient Network to build the queries.
When MdnsSearchOptions.network is null, one MdnsServiceTypeClient is
created for each mDNS-compatible Network. Each MdnsServiceTypeClient
schedules queries with a Network selector. If the Network selector is
null, each MdnsServiceTypeClient will post its queries to all networks.
Instead, it should be the Network of the MdnsServiceTypeClient.
There is one remaining problem when a tethered interface is up: in that
case, there will be one MdnsServiceTypeClient for tethered interfaces
with a null network, which will still broadcast its queries to all
networks. This should be addressed in a follow-up by having
MdnsMultinetworkSocketClient only send queries to interfaces that have a
null network, when the network selector is null (and not all
interfaces).

mDNS is supposed to be case-insensitive (like DNS). Both advertising and
discovery logic should use case-insensitive matching instead of
case-sensitive matching.
The case sensitive matching can be found by grepping the String.equals()
and Arrays.equals() check across the whole code base. Each occurrence is
analyzed carefully to list up all necessary fixes.

MdnsServiceTypeClient should stop sending when it is removed due to its
socket being destroyed.
On null networks (downstream interfaces) that may have multiple sockets,
this should only happen once the last socket used by the (null) network
has been destroyed.

When a SocketCallback is unregistered from MdnsSocketProvider, do not
send socket destroyed callbacks. Callers may not expect getting
callbacks after unregistration, and the current callbacks are also
broken when an unrequested socket is still in use by another requester.
MdnsAdvertiser already does not depend on getting this callback, as it
only unregisters the SocketCallback after it is done using the socket.
This change fixes MdnsMultinetworkSocketClient to destroy the socket by
itself when unrequesting.

Implement subtype advertising by advertising an additional PTR record if
subtype advertising was requested.
For an advertiser a subtype is just an additional PTR record, so this
just involves plumbing the subtype down to MdnsRecordRepository, which
includes the additional record in the service registration.

Apps may want to discover a particular subtype, such as
_color._sub._printer._tcp.local, which may return services like
Printer1._printer._tcp.local. The previous code was trying to discover,
and would return service types named _color._sub._printer._tcp.local,
even though the actual service type is still _printer._tcp.local. This
is a regression compared to S/T.
Fix this by passing the subtype to MdnsDiscoveryManager in its options
instead of the service type, and ensure that MdnsDiscoveryManager only
sends callbacks to callers that have requested the given subtype (a
color that asked for _color._sub._printer._tcp.local should not receive
BlackAndWhite._printer._tcp.local).

Historical behavior of onServiceFound is to include a dot at the end of
the service type. To avoid inconsistencies between behavior of new and
older backend, which would be hard to predict/handle for apps, ensure
that the same format is used. This means a dot must be added when using
the new backend.
Implement this by creating the callback service types based on
MdnsServiceInfo obtained from MdnsDiscoveryManager, rather than the
service type that was provided by the calling app. This avoids
inconsistencies as the calling app may or may not include dots
originally, and it may use subtypes ("_sub._type._tcp.local" or even
"_type._tcp.local,_sub"), which would result in callbacks giving invalid
service types, or inconsistent with S/T behavior.

Currently, native networks for non-VPN networks are created only
when the NetworkAgent goes into the CONNECTED state. This is not
ideal, because until the network is connected:
- Nothing routes to the network, so no IP packets can be sent on
it (except via packet sockets).
- Many network configuration changes (e.g., routes and DNS
servers) fail to apply because the network does not exist yet.
These cause ENONET errors in the logs.
Fix this starting in U by creating the native network as soon as
the agent registers. This should not impact apps because
NetworkCallbacks are not sent until networks are connected.
