Add options to control whether only send IPv6 packet on IPv6 only
network. In some use case, IPv6 query should not be sent on a dual
network.
Added a small improvement to send an ANY query if both SRV & PTR

Currently, various codepaths in ConnectivityService disconnect
networks using NetworkAgentInfo#disconnect. This posts a message
to the NetworkAgent to disconnect and also posts a message to
ConnectivityService to call disconnectAndDestroyNetwork, which
performs all cleanup in ConnectivityService. These two messages
race and the order is non-deterministic.
Instead, always disconnect using disconnectAndDestroyNetwork,
and have disconnectAndDestroyNetwork post the message to the
agent to disconnect.
This fixes a bug where if wifi uses unregisterAfterReplacement
twice in quick succession, when the third agent connects it
doesn't work because the interface is still being used by the
second network.
Also remove the import of IllegalArgumentException to keep the
linter happy (java.lang.* never needs to be imported).

Now, MdnsServiceTypeClient is created using a network. However,
all tether interfaces use the same network (null), which
means they use the same client for the same service type. This is
not the intended behavior, as each interface should have its own
client. Therefore, MdnsServiceTypeClient creation should be
changed to use SocketKey, which includes both the network and
interface index. This will allow each interface to have its own
client.

When a TCP keepalive start request is sent from ConnectivityService
to KeepaliveTracker, the keepalive is tracked on both
AutomaticOnOffKeepaliveTracker and KeepaliveTracker. The existing
design stops the keepalive inside KeepaliveTracker without
notifying AutomaticOnOffKeepaliveTracker for fd initiated stops.
This causes AutomaticOnOffKeepaliveTracker to lose track of these
fd initiated stops and cause a leak on the object.
The updated design sends the event to ConnectivityService handler
to handle the event down from ConnectivityService. This ensures
that each stakeholder class will get the stop event.

When the cache flush bit is set on host address records in a response,
known records are cleared and replaced with the contents of the packet.
However even if the response contains the same records as before, this
caused it to be marked as modified, and response modified callbacks are
sent for every incoming packet.
Instead, ensure that the response is only marked as modified if a
previously unknown address record is added, or if a previously known
address record is removed.
The issue wasn't found by the existing testDecodeWithNoChange test,
because it used a service record for testhost2 instead of testhost1, so
the address records were ignored.

If the MdnsServiceTypeClient was removed when the
SocketCreationCallback#onAllSocketsDestroyed() was called, the
MdnsSocketClientBase#notifyNetworkUnrequested() will not be
called when a listener is unregistered from the
MdnsDiscoveryManager. This is because the serviceTypeClients will
be cleared after the socket is destroyed. However, these dead
listeners will be re-added to the MdnsServiceTypeClient when a
new socket is created. They will then continue to send callbacks
to the NsdService. Therefore, the notifyNetworkUnrequested()
should be moved to the beginning of the handleRegisterListener()
to ensure that the socket unregistration is properly notified.

When an mDNS request (discovery, advertising, resolving...) is
registered and gets assigned a socket on a wifi network, take the
multicast lock to ensure that it can reliably receive mDNS responses.
This is limited to when the application has importance
FOREGROUND_SERVICE or higher.
NsdManager is not documented to require usage of the multicast lock,
which has caused various reports about its reliability. Taking the lock
while the app is in the foreground should address the large majority of
cases, while limiting battery impact.
Going forward this should allow developers on U+ to not take the
lock themselves, allowing optimizations on devices supporting APF,
where instead of taking the lock APF would let through only select
mDNS packets.

See system/netd/include/Fwmark.h which reserves the bottom 21 bits
of skb->mark for netid, etc... so out of necessity these have to be
in the top 11 bits.
In practice the only values that really make sense are either:
mark == mask == 0 (disabled)
or (mark == mask) being one of the top 11 available bits, for example:
mark == mask == 0x80000000 (enabled, using top-most bit)
(only a single bit makes sense, as this is really just a boolean signal,
and only the topmost is known to be used on any real devices)
Let's just force the use of 0x80000000 for ecosystem consistency.

If there is no request for all networks, the tethered/local only
interface changes will be ignored. However, these available
interfaces are not used for mDNS when a user requests a socket
with a null network because the interfaces are lost due to the

retained and will be used for socket creations afterwards.

mDNS is used by wifi p2p in many places. However,

connection to get the names of the available wifi p2p interfaces.
