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.

Test: could not repro b/36902662, reportNetworkConnectivity() works.

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.

The testNotificationsShownAndCleared test was not doing anything
because the list of notification to show was always empty.
This patch fixes this issue and actually makes the test loop on
non-empty collections, and also fixes another ordering issue in
assertions themselves, hidden until now by the first issue.

netId logging for this event to the topt-level netId field in
ConnectivityMetricsEvent.

This patch deprecates the ifname field for specific metrics events of
types DhcpClientEvent, DhcpErrorEvent, IpReachabilityEvent and
IpManagerEvent.
Instead ifnames are logged in ConnectivityMetricsEvent, allowing for
link layer inference.

Change-Id: I8bfabcb115bbd5289471d653c153a40bb48f28cd
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.
At the moment these new fields are not populated in
ConnectivityMetricsEvent. Follow-up patches will fill this gap for
the events of the android.net.metrics package.

This patch adds new fields to ConnectivityMetricsEvent to make it more
symmetric to IpConnectivityEvent in ipconnectivity.proto.
Follow-up patches will start populating these fields for users of
IpConnectivityLog.

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.

This patch:
- adds a counter to ConnectStats for counting the number of successful
connect() calls done in blocking mode. This allows to compute error
rates for connect() in blocking mode.
- add printing of ConnectStats when dumping NetdEventListenerService
and/or IpConnectivityMetrics service.
Test: $ runtest frameworks-net, + manual tests verifying logged events.

Add (unhide) a public API which provides network requests with a
timeout. When timed-out the (newly unhidden) onUnavailable() callback
is triggered.
Note: this CL does not add a handler to the API to be consistent
with the existing APIs. There is a separate effort (b/32130437)
to update these APIs with Handlers.
