Not all SocketTypeClients are cleaned up when their corresponding
sockets are closed. This occurs because the active socket check
for each callback examines the socket from all callbacks, even
those scheduled for removal in later notifications. To fix this,
check the active socket from the current callback only.

When sockets are destroyed, the SkDestroyListener receives a
NETLINK_INET_DIAG message informing it to delete the socket cookie from
the BPF CookieTagMap. However, under unknown conditions, all 10,000
spaces on the map were still observed to be filled. SkDestroyListener
and its parent classes, NetlinkMonitor, and FdEventsReader will log
errors. But due to the time required to fill the 10,000 fields is long,
traces in the device log are likely to have been overwritten and cannot
be observed.
This commit enables dumpsys netstats to print the last 20 traces of the
SkDestroyListener. If the issue is caused by the SkDestroyListener,
this will help in obtaining further clues when the issue is reported
again.

The original patch (aosp/2891011) incorrectly counted TCP
sockets with keepalive enabled for VPNs. This issue was
caused by the UID range verification. On bypassable VPNs,
the socket mark is always correct. It's possible for an
app that is not in the UID ranges to establish a socket
on the VPN. But that socket should be counted for the
purposes of keepalive. The old code would correctly count
it and the new code will incorrectly not count it. Also,
the UID range verification does not help on non-bypassable
VPNs since the socket mark is always the mark of default
network, not the socket mark of the VPN.
Instead of reverting the entire patch, this commit
removes the UID range mechanism. The code refactoring from
the original commit (which used structured classes to read
socket information) has been kept as it is a valuable
improvement.

Fix current leaks in CSTest related tests, which leaked the
ConnectivityService and AlarmManager handler threads, and enable
the checks.
Using @DevSdkIgnoreRunner.MonitorThreadLeak ensures that tests properly
cleanup threads (in particular handler threads), as many leaked threads
could affect other tests.

Instead of (wrongly) looking at the DNS message flags for the Query
Unicast bit, look at the flag in the question record.
The previous bug means that all queries would be replied multicast
instead of sometimes unicast. The fix is flagged off as this is a
behavior change that may affect performance and latency.

MulticastPacketReader uses an InetSocketAddress as a buffer that gets
filled for each incoming packet for the source address. Similarly to the
receive buffer, it should not be used outside of the handlePacket
method, as it will be modified on the handler thread when further
packets are received.
Fix the current usage in MdnsInterfaceAdvertiser/MdnsRecordRepository.
Fortunately due to a bug packets are never replied unicast, so today the
MdnsRecordRepository code using the source address never triggers, even
though it may be circulating an incorrect source address instance that
changes over time.

NsdService switched from Netd native solution to Java solution on
Android U. MDNS service provided by Netd will be removed from Android V.
1. Stop registering native mdns service from V.
2. Stop startDaemon() in NsdManager from V.
3. As a double safety, return early in NsdService methods that call the
native mdns service when platform version is V+.
4. Modify NsdManagerTest to cover V+ behavior.

Log.wtf should avoid crashes, while making sure that one can still
notice if there is a problem.
In particular, it may be possible that calling ensureIpServerStopped
and ensureIpServerStarted could start forwarding before the previous
IpServer has stopped it.
