Network specifiers are used for 2 purposes:
- As part of network requests to specify more information on the type
of requested networks.
- On network agents to specify information about their networks.
The network specifiers of the requests and agents are matched to each
other. However, the agent network specifier may contain sensitive
information which we do not want forwarded to any app.
This CL adds an option to strip out this agent network specifier before
the network capabilities are forwarded to the app.

PermissionMonitor#hasPermission only checks permssions that app
requested but it doesn't check whether the permission can be
granted to this app. If requested permission doens't be granted
to app, this method still returns that app has this permission.
Then PermissionMonitor will pass this info to netd that means
this app still can use network even restricted network without
granted privileged permission like CONNECTIVITY_INTERNAL or
CONNECTIVITY_USE_RESTRICTED_NETWORKS.
PermissionMonitor#hasUseBackgroundNetworksPermission only uses
the first package name of the uid for checking permission.
This is incorrect since each package declared different
permissions. So using the mApps which already checked both
network and using restricted network permissions. If uid is in
the mApps list that means uid has one of permission at least.

Currently, strict mode private DNS does not work on VPNs because
NetworkMonitor does not validate VPNs. When a VPN connects, it
immediately transitions to ValidatedState, skipping private DNS
hostname resolution.
This change makes NetworkMonitor perform private DNS hostname
resolution and evaluation even on VPNs.
In order to ensure that the system always immediately switches to
the VPN as soon as it connects, remove the unvalidated penalty
for VPN networks. This ensures that the VPN score is always 101
and the VPN always outscores other networks as soon as it
connects. Previously, it would only outscore other networks
when no-op validation completed.
Backport of c455822846.

Support faking out the DNS lookups used by NetworkMonitor to
resolve strict mode DNS, and add more test coverage.
These tests were partly adapted from tests we have in Q but
also contain new coverage. This is because in Q the interface
between ConnectivityService and NetworkMonitor changed
substantially, and it is impractical to backport
NetworkMonitorTest.

The "Connected" notification would be shown every time a network
validates after being identified as a captive portal. This causes issues
on networks that have auto-login mechanisms, as a high priority
notification would be shown even though the user was not interacting
with the phone.
The "Connected" notification is intended to confirm to the user that
they successfuly logged in (manually), so only show it after the user
opens the portal on the network.

(cherry picked from commit 833603caabb1a850a63a970fc285b4c8ed7401f8)
This change fixes detailed UID stats to ensure network and battery stats
both take VPNs into account. NetworkStatsFactory is being made aware of
VPNs enabled, and the full set of underlying networks present.
Since traffic can only be migrated over a NetworkStats delta, NSF
maintains a NetworkStats snapshot across all UIDs/ifaces/tags.
This snapshot gets updated whenever NSF records a new snapshot
(based on various hooks such as VPN updating its underlying networks,
network getting lost, etc.), or NetworkStatsService's
getDetailedUidStats() method being called.
This change widens the scope of the existing mPersistentSnapshot lock,
renaming it to mPersistentDataLock, and ensures that TUN migrations are
not done in parallel. Additionally, mVpnInfos is updated via
pointer-swapping, to reduce the scope of the mPersistentDataLock.
The safety of this change is predicated on:
1. NetworkStatsFactory lock not held, so services cannot deadlock through
the cyclical lock.
2. The broadening of the scope of the lock in NetworkStatsFactory has no
threading implications, as it is always the last (leaf node) lock held,
and therefore is impossible to have lock inversion.
Additionally, to ensure VPNs work with 464xlat, the VPN info passed to
the NetworkStatsFactory includes all underlying interfaces, instead of
only passing the first one.
This (partially) re-applies changes from:
aosp/972848: Add one more test for VPN usage stats.
aosp/972847: Addressing comments for http://ag/7700679.
aosp/885338: NetworkStatsService: Fix getDetailedUidStats to take VPNs

If fd is reused for another query during that gap, it might cause the

This will allow wifi to tell ConnectivityService that partial
connectivity is acceptable even if the network is not explicitly
selected.
This is needed when the user selects a partial connectivity
network and tells the system to connect to the network, and never
to ask again. In such cases, the system must switch to the
network even if it is not explicitly selected.
