NetworkMonitor cannot do the private dns resolution due to lack
"mNetworkCapabilities". ConnectivityService will call
NetworkStackService#notifyPrivateDnsChanged() before doing
network validation. After NetworkMonitor received
CMD_PRIVATE_DNS_SETTINGS_CHANGED, it will call
isValidationRequired to check if the validation is required.
But mNetworkCapabilities didn't be set, so the
mPrivateDnsProviderHostname will be set to empty and make
EvaluatingPrivateDnsState doesn't do private dns resolution.

The kernel eBPF maps have a blacklist to store all the uids that doesn't
have internet permission. When an app is unintalled from the device and
it is the last package on device that uses that uid, make sure we
cleaned the uid from the map and do not add no longer used uids into the
eBPF map. This action helps reduce the number of entries stored in the
map and reduce the chance of overflow the eBPF map.

Fix: 129097486
Test: atest FrameworksNetTests
Currently, onStopped callback are synchronizely triggered when
stop() was called, since the framework don't really care
about the result of stopping keepalive.
However, if keepalive failed to stop for some reason, the
handleStopKeepalive was called mistakenly and trigger additional
callback that fail the test case.
This commit is the behavior change prior to state machine
refactoring, and introduce a stopping state for ignoring the
result in the stopping state.

The system server (in SystemServer.java) defines the boot
sequence, during which an event called SystemReady happens.
This corresponds to a time when critical system services
that are depended upon by other components in the system
server are ready to handle requests from their dependencies.
Some system services are listening to this event to defer
initializations that depend on the critical services.
Because the network stack is only started after SystemReady,
there is no way any NetworkMonitor may be started before
SystemReady. Remove the associated mechanism.

NetworkMonitor obtained LinkProperties and NetworkCapabilities via
synchronous calls to ConnectivityManager after receiving an asynchronous
notification, which is prone to races: the network could be gone before
the LinkProperties/NetworkCapabilities can be fetched.
Fix the race by passing LinkProperties/NetworkCapabilities directly to
NetworkMonitor in the asynchronous notifications.

* changes:
Move BatteryStats and StatsCompanionService to use NetworkStatsService.
NetworkStatsService: Fix getDetailedUidStats to take VPNs into account.
Take all VPN underlying networks into account when migrating traffic for VPN uid.
This API is similar to one provided by NetworkStatsFactory with the
difference that NSS also migrates traffic from VPN UID to other apps.
Since traffic can only be migrated over NetworkStats delta, NSS
therefore maintains NetworkStats snapshot across all UIDs/ifaces/tags.
This snapshot gets updated whenever NSS records a new snapshot
(based on various hooks such as VPN updating its underlying networks,
network getting lost, etc.), or getDetailedUidStats API is invoked by
one of its callers.

Currently, socketKeepalive implementation is accepting null fd
due to backward compatibility with legacy packet keepalive API.
However, due to lack of the fd, the service cannot guarantee the
port is not reused by another app if the caller release the port
for any reason.
Thus, grant the null fd access only for priviledged apps.

Currently, if the lower layer, e.g. wifi, didn't successfully
start keepalive by any reason. Due to the startedState changed
to NOT_STARTED first, the logic inside stop() will skip the
removing process and cause leak.

to unblock subsequent changes first.

There are 2 problems will make testPartialConnectivity flaky:
1. If we call setNetworkValid() before expectCapabilitiesWith(),
there may be a timing issue that network will become VALID before
NetworkMonitor send PARTIAL_CONNECTIVITY to ConnectivityService.
Solution:
We should set network to valid after ConnectivityService received
NETWORK_TEST_RESULT_PARTIAL_CONNECTIVITY to ensure NetworkMonitor
will send PARTIAL_CONNECTIVITY to ConnectivityService first then
send VALID.
2. When test case call explicitlySelected(true) first then call
connect(true), NetworkMonitor will report the network validation
test result twice because ConnectivityServiceTest() will trigger
notifyNetworkTested() when setAcceptPartialConnectivity() is
called, it may cause a timing that before the second test result
send to ConnectivityService, connect() already called
setNetworkInvalid. So, NET_CAPABILITY_VALIDATED will be removed
and ConnectivityService will trigger onCapabilitiesChanged()
unexpectedly.
Solution:
Don't trigger notifyNetworkTested() when
setAcceptPartialConnectivity() is called. If there is needed,
use mCm.reportNetworkConnectivity() to report the test result
instead.
