This patch moves reportNetworkConnectivity onto the handler of
ConnectivityService.
This allows:
- to inspect NetworkAgentInfo on the ConnectivityService handler,
which is always more correct than doing so on a Binder thread.
- to improve locking policies around NetworkAgentInfo.

This path changes a dangerous lock path in reportNetworkConnectivity().
This methods is called outside of the main ConnectivityService handler
and takes a lock on a specific NetworkAgentInfo whose connectivity
status is being reported.
While this lock is held, reportNetworkConnectivity() goes on and query
the network policy state for that network, which may ends into
NetworkPolicyManagerService.
Instead, the lock on NetworkAgentInfo is only held long enough to make a
copy of LinkProperties, which is then passed to
NetworkPolicyManagerService without that lock.
Bug: 36902662
Test: could not repro b/36902662, reportNetworkConnectivity() works.

Most @SystemApi methods should be protected with system (or higher)
permissions, so annotate common methods with @RequiresPermission to
make automatic verification easier.
Verification is really only relevant when calling into system
services (where permissions checking can happen on the other side of
a Binder call), so annotate managers with the new @SystemService
annotation, which is now automatically documented.
This is purely a docs change; no logic changes are being made.

Introduce a SharedLog that can be shared among all Tethering
components. All log entries go to the same log, and each includes
its subsystem name. Additionally, all entries emitted to the
system log shared the same tag, so can easily be watched.
More subsystems can inherit a SharedLog, but to minimize cherry-pick
conflicts we limit ourselves to these changes only.
Test: as follows
- built
- flashed
- booted
- log output observed via dumpsys

For 464xlat scenarios on IPv6 networks, the clatd interface setup
introduces double counting of apps ipv4 traffic. NetworkStatsFactory was
accounting for this on the tx path, but not on the rx path. Also it did
not accounted for the 20 bytes added by the IPv6 header.
This patch subtract correctly the rx and tx traffic from the root uid on
the underlying interface, and also adds correctly the 20 bytes cost per
packet on the stacked interface for 464xlat traffic.
Test: added several new unit tests, based on synthetic data and real
data also.

If anything unrestricted is bundled in the whole thing has to be
unrestricted (we can't restrict based on destination or intent)
but the NOT_METERED flag wasn't taken into account.
This wasn't a problem before because telephony set that statically
and late, but a change caused it to be marked NOT_METERED earlier
which exposed this bug.

This patch changes how DnsEvents are logged in IpConnectivityMetrics.
The following changes are made:
- DnsEventBatch are not logged after 100 queries on the same network
- this allows to merge DnsEvent and DnsEventBatch into one class
- DnsEventBatch are not logged after a network disconnect
- this allows to remove the NetworkCallback
- DnsEvent are now logged similarly to ConnectStats when statistics are
flushed, in a direct call from IpConnectivityMetrics into
NetdEventListenerService, in a direct call from IpConnectivityMetrics
into NetdEventListenerService.
- this allows to remove the Parcelable implementation of DnsEvent
- transports information is added to DnsEvent.
Test: - simplified NetdEventListenerServiceTest covering dns logging
- updated IpConnectivityEventBuilderTest
- updated IpConnectivityMetricsTest
- $ runtest frameworks-net passes
- manually verified $ adb shell dumpsys connmetrics list proto

This change introduces new methods on DumpUtils that can check if the
caller has DUMP and/or PACKAGE_USAGE_STATS access. It then moves all
existing dump() methods to use these checks so that we emit
consistent error messages.

This patch removes from ConnectivityService the logic involved in
deciding if a uid has access to networking based on networking policies.
This logic is moved into NetworkPolicyManagerService which is the source
of truth with regards to the state of networking policie, both for
existing networks and uids.
Instead ConnectivityService directly queries NetworkPolicyManagerService
in a synchronous fashion for a specific uid or a (uid, network) pair.
This eliminates the need to keep a copy of the uid policy rules inside
ConnectivityService and ensures that ConnectivityService takes
networking decisions based on the correct state of networking policies,
and therefore eliminates certain data races in ConnectivityManager API
that applications are exposed to.

This patch adds translation from ConnectivityMetricsEvent to
IpConnectivityEvent of recently added fields:
- top-level network id
- top-level ifname
- transports
Also adds inference of link layer from transports or ifname.

ConnectivityMetricsEvent. Follow-up patches will fill this gap for
the events of the android.net.metrics package.

This patch adds a few missing counters to APF events:
- an actual lifetime duration to ApfProgramEvent.
- counters for total number of updates to ApfStatistics.
ApfProgramEvents are now recorded at program removal in order to
populate the actual lifetime of the program. ApfProgramEvents whose
actual lifetime was less than 1 second are filtered out.
Finally, instance fields of ApfProgramEvent and ApfStats classes are
made mutable to allow for simple record-like creation. This was not
possible when these classes were tagged @SystemApi.
Test: - manually verified output of $ dumpsys connmetrics list
- unit tests updated.
