With bursty WiFi traffic, we end up sampling the WiFi controller's
energy data quite a lot. Extend the timeout so that we sample
once there has been no activity for 15 seconds.
Note: Once the WiFi radio goes down after being active, it can come back and be
active in less than 15 seconds, which means we may sample twice quickly.

It's not clear what it means to request a network with a mutable
NetworkCapability like NET_CAPABILITY_VALIDATED or
NET_CAPABILITY_CAPTIVE_PORTAL. Presently requesting such a network
would fail in a number of different ways:
1. The NetworkFactories would fail to match the request against their
filter which doesn't include stateful NetworkCapabilities.
2. If the NetworkFactories did match, they'd bring up networks to try
and satisfy the requests, but the networks would not have any
mutable NetworkCapabilities initially so they'd be reaped.
Because of these problems it's safest to simply disallow these
requests.

Without this fix if a listening NetworkRequest with NET_CAPABILITY_VALIDATED
is submitted after a network has been validated but failed the most recent
validation attempt, the NetworkRequest will never receive callbacks.

Before falling back to cellular we used to first delete all the
network routing tables and rules for WiFi. This isn't necessary
and can take significant time as it requires a lot of netd
shelling out to ip and ip[6]tables to flush routes and remove
the incoming packet mark rule. Instead have netd delete all the
network routing tables and rules after we've either fallen back
to cellular or at least kicked off a cellular connection attempt.

Without this API we're more or less encouraging apps to have long running
processes (battery draining) to receive NetworkCallbacks for the stateful
NetworkCapabilities NET_CAPABILITIES_VALIDATED and
NET_CAPABILITIES_CAPTIVE_PORTAL. With this API they can instead using
PendingIntents which outlive their apps.

Select only DNS servers that:
- are reachable, according to routes in the LinkProperties, AND
- have a "suitable" source address in the LinkProperites, meaning:
- IPv4 DNS server:
- only if LinkProperties has any IPv4 address
- IPv6 link-local DNS server:
- only if the server has a scopeId set
- assume for now that LinkProperties has a suitable
link-local address
- IPv6 non-link-local DNS server:
- only if LinkProperties has a global, preferred IPv6 address

- There are no callers of
NetworkInfo.setIsConnectedToProvisioningNetwork(), so remove all the
code that deals with mIsConnectedToProvisioningNetwork being true,
including the two ConnectiviyManager APIs.
- There are no callers of
ConnectivityManager.getMobileRedirectedProvisioningUrl(), so remove
the code that reads this URL.
- There are no callers of
ConnectivityManager.captivePortalCheckCompleted(), so remove this
API which is currently a no-op.

Overlapping the NetIDs can cause the ConnectivityService instance under test
to inadvertently use real networks, for example when NetworkMonitor attempts
to validate a network. This fixes test hangs when run on devices with
active internet connections.

Previously, we displayed a dialog on top of whatever the user was
doing. Instead, display a notification that can take the user to
the dialog.
Because the notification is less intrusive, also enable it even
if the network without Internet access is already the system
default network. Previously we did not do this because in that
case the user might not have other useful options, and thus a
dialog would have been too intrusive.

1. Always keep ConnectivityService's validated bits current:
- Apply the validated bit whenever a NetworkAgent updates its
NetworkCapabilities.
- Set or clear the validated bit whenever lastValidated changes.
2. Send callbacks when the validation state of a network changes.
3. Delete getNetworkCapabilitiesAndValidation, removing code
duplication with getNetworkCapabilities.
4. Add the validated bit to NetworkCapabilities#toString.

Settings and SystemUI need to act on other users than USER_OWNER.
This is gated by INTERACT_ACROSS_USERS_FULL in addition to the existing
CONTROL_VPN checks, so the number of processes able to interfere with
other profiles' VPNs should be quite small.

Because LegacyTypeTracker#remove can send broadcasts that cause
apps to refresh their view of network state, it needs to be
called only after network state has been updated. This requires
that callers determine whether the network was the default, and
updating state, before calling remove().
While I'm at it, fix maybeLogBroadcast's concept of whether the
network it's logging about is/was the default. This has never
been correct.

Firewall can now be in whitelist (old) or blacklist mode. When in

The compatibility measure introduced in bug 20081183 for apps
that connect to a Wi-Fi network without Internet access and then
expect to be able to use that network requires that such apps
register a NetworkCallback so that their WifiManager can pin them
to whatever wifi Network connects.
Currently, registering the callback requires ACCESS_NETWORK_STATE
and the app may not have that permission. Allow registering wifi
(only) callbacks if the app has ACCESS_WIFI_STATE.
If the app does not have ACCESS_WIFI_STATE (unlikely, since
CHANGE_WIFI_STATE is not very useful without ACCESS_WIFI_STATE),
then don't enable the compatibility measure.
