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.

This patch extracts into BitUtils byte manipulation helper methods
and unsigned type manipulation helper methods from ApfFilter into
an independent and reusable structure.

Wifi Aware networks are per app - i.e. a requestor gets
a dedicated network. Change verifies that the only the
original requestor matches the created network (using UID).

(cherry picked from commit dfc2cc5857199345e08f07977b79b20292f964a2)
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 groups them together with the rest of the networking unit
tests. It also speeds up compile/test cycles ("runtest -x" of one
file goes from 1m15s to 30s).

This allows an application that knows how to provide seamless

doing so is desired.

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.

Firewall rules don't work on 464xlat because they were created under
an assumption that there's only one address for the server and it's
ipv4, which doesn't go so well when we're on an ipv6-only network.

This cleanup helps declutter ConnectivityService, and encapsulates the
always-on setting inside of Vpn instead of spreading it across two
classes.
In particular having the save code in one file and the load code in
another file was weird and I apologise for that.
Added a SystemServices wrapper for Settings.Secure and PendingIntent
calls to decouple some of the global state nastiness and make it
testable without forcing ConnectivityService to drive the load/save.

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.

This patch deprecates the ifname field for specific metrics events of

IpManagerEvent.
Instead ifnames are logged in ConnectivityMetricsEvent, allowing for

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.
