Split-tunnel VPN (which are the only ones affected by this change)
always fall through to the default network for routes they don't
handle, and even if the underlying network(s) don't provide access
this may be a pinhole that can actually reach the broader network.
In practice this behaves like the original release of P and is the
safest thing to do for Q. In R we should evaluate giving the VPN
app the ability to simply tell the network stack whether it does
provide Internet access or not.

No internet notification may be prompted before partial
connectivity being detected. Partial connectivity status will
be set into NAI and prompted in the Setting. Behavior is not
aligned between Setting and notification. Thus, update
notification again if partial connectivity is detected.
Also, sliently show the updated notification if no internet
notification has already been shown to user to prevent alerting
user in short time.

Bug: b/133174607
Test: Manual. The simplest artifact is observed by watching the output of
adb shell dumpsys meminfo -d com.android.networkstack | grep 'Proxy Binders'
while connecting and disconnecting multiple times to any network.
This will display the number of binder proxies. Before this, the binder
proxy count increases by 1 with each connection and never goes down (there
is some noise, as proxy objects are sometimes created for other reasons,
and get GC'd eventually). After this, the binder proxy count is always
eventually stable at 27 + connected network count.
See the bug for the complete analysis.

Auto-reconnecting to a network with no or limited Internet
connectivity is not useful. This is because such networks cannot
be used unless the user taps the notification and interacts with
the resulting dialog. But the notification is only shown if the
user manually connects to the network, not if the system
auto-connects to it.

1. Previously, getDnsNetId doesn't handle all the cases.
Fix it with cosidering bypass private DNS flag.
2. Make getDnsNetId return Network instead of netId,
and change name from getDnsNetId to getDnsNetwork

Add one more test for VPN usage stats.
Addressing comments for http://ag/7700679.
NetworkStatsService: Fix getDetailedUidStats to take VPNs into account.
Take all VPN underlying networks into account when migrating traffic for VPN uid.
Covers the case where the majority of traffic through the VPN is
caused by the VPN app itself, and ensures that that traffic is
correctly attributed to the VPN app as opposed to spread between
the other apps that use the VPN.

(cherry picked from commit 2af0b66aba)
This API is similar to one provided by NetworkStatsFactory with the
difference that NSS also migrates traffic from VPN UID to other apps.
Since traffic can only be migrated over NetworkStats delta, NSS
therefore maintains NetworkStats snapshot across all UIDs/ifaces/tags.
This snapshot gets updated whenever NSS records a new snapshot
(based on various hooks such as VPN updating its underlying networks,
network getting lost, etc.), or getDetailedUidStats API is invoked by
one of its callers.

Test: manually verified that battery stats are migrating traffic off of
TUN (after patching above CL where we point BatteryStats to use this
API).

was failing on devices with a first released SDK >= Q
- Add a test actually tests that the system has the permission, as
the test was only testing what's in the mock

meant to be usable in framework tests, network stack tests, CTS,
