Currently, every call to avoidBadWifi fetches the current value
of the config variable and setting whenever it is called. This
means that the score of an unvalidated wifi network can
unpredictably change at any time, creating a data race.
Instead, persist the value and only update it when something
changes.

This patch adds a way to configure devices so that a validated network
that becomes unvalidated is not penalized in the network scoring and
selection logic.
The intent is to prevent devices configured to do so from switching to a
lower scoring network such as cellular networks when a higher scoring
network such as wifi networks loses internet connectivity.

This allows simplification of getCurrentScore function in
NetworkAgentInfo and its return value to depend on everValidated and
lastValidated.

Like a normal (foreground) request, a background request is only
satisfied by one network and will keep that network up. Unlike a
foreground request, when a network only has background requests,
it will linger, and after lingering is complete, it will become
a background network.
Future CLs will cause the system to treat background networks
differently, e.g., by requiring different permissions.

This CL splits rematching in two parts: first rematch requests,
then rematch listens. This will allow us to change a network's
capabilities depending on what requests are on that network, and
properly dispatch callbacks depending on those capabilities.
The behaviour changes are as follows:
- Before this CL, callbacks for requests and listens were sent
intermingled. After this CL, all request callbacks will be
grouped together, and all listen callbacks will be grouped
together.
- Before this CL, the order was:
1. Send onLost callbacks.
2. If applicable, switch the default network.
3. Send onAvailable callbacks.
After this CL, the order is:
1. Send onLost callbacks for requests.
2. If applicable, switch the default network.
3. Send onLost callbacks for listens.
4. Send onAvailable callbacks for listens.
5. Send onAvailable callbacks for requests.
These changes shouldn't affect any apps because:
1. The order of callbacks continues to be first all onLost,
then all onAvailable.
2. Both the old and the new code send callbacks in no particular
order. Thus, the possible ordering combinations of callbacks
in the new code are a strict subset of the possible ordering
combinations of the old code.
3. The default network is switched before any onAvailable
callback is sent.
4. Even though the new code does not send all onLost callbacks
before switching the default network, even before this CL
there was no guarantee that those callbacks would be received
before the default network switch anyway, because callbacks
are asynchronous.

Add TRANSPORT_WIFI_NAN - specifies a peer-to-peer Wi-Fi NAN data
connectivity request.
While NAN uses Wi-Fi L1 PHY and part of the MAC - it is a different
protocol and constitutes a different transport.

This patch adds a daily limit to the maximum number of notifications
shown when switching networks.
It also adds a rate limit to prevent rapid successive notifications in
flapping scenarios.

Sometimes we switch away from a network to another (e.g., wifi to
cell data) not because the old network is unvalidated, but
because the score is lowered by a low signal strength.
In this case, don't notify the user of a network switch.

1. Move from deprecated network types to transport types.
2. Rename and simplify (by passing in a NetworkAgentInfo object)
the call signature of the method that displays notifications.
3. Add a method to clear notification, and unindent lots of code.
4. Move the legacy DcTracker-issued notification code to
NetworkNotificationManager.

Similarly to ApfTest, this patch changes ConnectivityServiceTest to use
a mock object instead of IpConnectivityLog so that running
ConnectivityServiceTest does not generate android.net.metrics events.

This patch creates a new permission used by ConnectivityService to give
access to restricted networks without the NET_CAPABILITY_NOT_RESTRICTED
capability bit on.

Add an IPv6TetheringCoordinator to TetheringMaster StateMachine, which
receives and processes NetworkState updates and passes the necessary IPv6
information to the revelant TetherInterfaceStateMachine.
Add an IPv6TetheringInterfaceServices to TetherInterfaceStateMachine, which
is responsible for adding local network routes and managing an IPv6
RouterAdvertisementDaemon.
