The underlying issue here is that before aosp/986824 the call to
waitForIdle is the local ConnectivityServiceTest function, but
after that patch TestNetworkAgentWrapper has an identically
named member that only wait for its own handler.

The current test we have for a package changing TrafficController
permissions (i.e., INTERNET or UPDATE_DEVICE_STATS permissions)
is not realistic.
This is because the test simulates the update by removing and
adding the package. But TrafficController permissions are not
driven by broadcasts, they are driven by PackageListObserver,
and when an app is updated, PackageListObserver does not see a
remove and and add, but a single change event.
Add a new test for this.

This timing issue is happened when test case already verified
NetworkMonitor#setAcceptPartialConnectivity() before
NetworkAgent send the CONNECTED state to ConnectivityService.
This test case expects that the
NetworkMonitor#setAcceptPartialConnectivity() will be invoked
when network state is CONNECTED in
ConnectivityService#updateNetworkInfo().
NetworkAgent communicates with ConnectivityService by
AsyncChannel. Before they connect to each other, the thread of
NetworkAgent is keeping idle, so waitForIdle cannot handle this
kind of case. Although they have connected to each other, but
they don't communicate with each other, waitForIdle() still
cannot handle this case. It means waitForIdle() can only handle
the case that NetworkAgent already connected to
ConnectivityService and NetworkAgent is communicating with
ConnectivityService. So, that's why waitForIdle() sometimes
doesn't work in this case, and the most simplest and right way
to fix this case is to wait the available callback then verify
the method.

If EVENT_NETWORK_INFO_CHANGED was handled after waitForIdle()
method done, this test will be failed due to
INetd#setTcpRWmemorySize() was not executed yet. Instead of
waiting for idle state, it's better to use NetworkCallback to
ensure events completely on ConnectivityService.

TestableNetworkCallback will become a standard tool. This patch
and its companion in packages/modules/NetworkStack mostly move
it out of ConnectivityServiceTest, but also applies a few
cleanups like reordering arguments for standard order, renaming
...Like to ...That to match Mockito namings, and introduces
stonger static typing on some callbacks, which allows to remove
some unchecked casts.

ag/7905088 added the ability to pass in acceptUnvalidated without
passing in explicitlySelected. Add unit tests for that code.
While I'm at it, convert a couple of "== 1"s to toBool(), and
update the comments in NetworkAgent.

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.

NetworkStatsService uses an internal boolean to know when it has
started for the purpose of preventing access to other internal
variables before they are initialized.
However that boolean is set to true in systemReady() non-atomically
with respect to the initialization of the other variables it guards,
which can cause the system server to crash.
This patch fixes this concurrency bug by moving setting the internal
boolean flag and the variable it guards in one atomic synchronized
block.
This patch also removes code checking if bandwidth control is enabled,
because this is now always true.

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
into account.
