This patch defines new Settings symbols for
- setting the probe urls for captive portal detection.
- setting which User-Agent to use for captive portal detection.
The existing default values for these settings are not changed, i.e:
- HTTP and HTTPS probes urls are unchanged.
- the fallback probe is not used.
- User-Agent is empty by default.

This patch adds the possitibility to send a 3rd fallback validation
probe in sendParallelHttpProbes when neither the 1st http probe nor the
https probe came back with a conclusive answer.
This 3rd probe is only used for trying again captive portal detection
and does not return success, so that network validation always fails if
the https probe fails.
In addition, the url reveals a captive portal is now sent to the
CaptivePortalLoginActivity so that all three probes can use different
urls.

When a network goes into the background, tell netd to set the
network's permission to NETWORK. Also, close all TCP sockets on
that network, to prevent long-lived TCP connections from staying
on it and possibly continuing to use metered data.

This patch connects existing IpConnectivityLog to the new
IpConnectivityMetrics service:
- IpConnectivityLog is now an independent class that pushes events
directly to the new IpConnectivityMetrics service.
- DnsEventListenerService is moved from MetricsLoggerService to
IpConnectivityMetrics.
- this patch also features end to end tests from IpConnectivityLog to
IpConnectivityMetrics dumpsys output.

This patch moves ipconnectivity.proto and companion serialization
classes from /vendor/google/app/ConnectivityMetrics into the framework
services jar.
This will allow to implement a dumpsys interface for IpConnectivity
metrics events defined in android.net.metrics that output metrics as
a serialized proto.

Currently, when the avoid bad wifi setting changes, we rematch
all networks and requests, but do not update any NetworkFactories
with new scores. This means that if a wifi network's score goes
down as a result of enabling bad wifi avoidance, we will not look
for another network (e.g., cell data) to satisfy its requests.
This makes it so that when the user enables avoiding bad wifi,
we will attempt to bring up cell data will if it is not already
connected.

No longer do this in ConnectivityService#tether/untether.
Instead, have Tethering do it when an interface is actually
tethered.

This contains the following changes:
1. Make NETWORK_AVOID_BAD_WIFI a tristate: 0 means never avoid
bad wifi, unset means prompt the user, 1 means always avoid.
2. Look at NETWORK_AVOID_BAD_WIFI only if the carrier restricts
avoiding bad wifi (previously, we relied on the setting being
null and defaulting to the value of the config variable).
3. Add an avoidUnvalidated bit to NetworkAgentInfo to track
whether the user has requested switching away from this
unvalidated network even though avoiding bad wifi is generally
disabled. This is set to true when the user selects "switch"
in the dialog without setting the "Don't ask again" checkbox.
4. Add a hidden setAvoidUnvalidated API to ConnectivityManager to
set the avoidUnvalidated bit.
5. Additional unit test coverage.

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.
