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.

If a listener request is fulfilled immediately from cache, do not
restart queries immediately, but just schedule the next run.
This avoids doubling the number of queries when discovery, then resolve

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.

If the network is null in MdnsServiceTypeClient, it should use
MdnsSocketClient for single socket only. So it's expected to
process any response from only the socket (network).
Move the stopDiscovery outside the listener check loop.
Because the stop should only be called once.
Add a test to verify the response processing with a non-null

From service-connectivity, NAMESPACE_TETHERING must be used, as
NAMESPACE_CONNECTIVITY is used for the NetworkStack module. Also the
isFeatureEnabled with module name must be used, otherwise the "android"
package version is queried instead of the tethering module version.
BpfNetMaps is using flag value 1 to workaround this issue.

The ConnectivityResources class is only usable with QUERY_ALL_PACKAGES
permission, so it is not generally usable in framework-connectivity. It
is also backed by the ServiceConnectivityResources APK, which is
intended as resources for service-connectivity.
Move the class to service-connectivity and update callers. CTS needs a
way to determine the supported keepalive count as it used the
resources from KeepaliveUtils as @hide API, so provide a
ConnectivityManager @hide API for testing.

Currently, the mDns discovery services will clear if no listener
registers to that MdnsServiceTypeClient. If an app does discover,
stop discover, resolve, at this point the listener was
unregistered, so the MdnsServiceTypeClient was deleted, and the
service is gone from cache. So this will actually restart
discovery without returning previous results from cache. Thus,
add MdnsServiceCache to store all services and reduce the
duplicated queries.

Currently, the MTU tests work on networks that have not yet been
connected. This is not very realistic because most MTU changes
(like most LinkProperties changes in general) happen after the
network has connected. Change these tests to use connected
networks instead.
To avoid losing coverage for setting the MTU before the network
is connected, add a test just for that.
