This patch removes static methods for logging IP connectivity events
defined in android.net.metrics and replaces them with a single log()
instance method defined on IpConnectivityLog. Event constructors are
now public also. Every classes logging such events now create an
instance of IpConnectivityLog for logging event objects directly
instantiated with new.
Removing static dependencies allow straightforward testing of logging.
This patch also removes the base IpConnectivityEvent class which is not
needed any more.

This patch adds synchronization inside LegacyTypeTracker so that
getNetworkForType() can safely run concurrently with remove().
Without synchronization if remove() removes the last network for a
given type while getNetworkForType() runs for the same type, it is
possible that getNetworkForType tries to access the head of an empty
list, resulting in a runtime exception.
This issue was found by zoran.jovanovic@sonymobile.com who proposed a
fix in AOSP (Change-Id: Ia963662edb9d643790e8d9439e4dbdcac4c2187b).
This patch differs from the fix proposed by the bug reporter and tries
instead to do the minimum amount of locking to make getNetworkForType
safe.

It's with the rest of the logic now and allows checking whether the
lockdown state matches, too, which led to a lot of misunderstandings.

All users should be made aware a captive portal is in place and be
given the opportunity to sign into the network. Without this fix
other users are not notified and given a chance to sign-in.

* changes:
Give WakeupMessage the ability to transport an object as well.
Don't treat the lingerExpired broadcast specially.
Add a test for mobile data always on.
Add a FakeSettingsProvider and use it in ConnectivityServiceTest.
NetworkMonitor no longer uses the broadcast for lingering, it
uses WakeupMessage instead.

This class makes it easier to test code that uses Settings:
1. Real device or emulator settings don't affect the code under
test; all settings always start off empty.
2. It's possible to change settings from the test without
affecting system settings.
3. No changes are needed to the code under test. The changes to
the tests are simple: just add a fake ContentResolver to
whatever mock Context is already used by the test, and make
that ContentResolver use the fake provider.

Fix 2 problems of always-on vpn after always-on package is removed
1. Prevent network being locked down (blocking all network traffic)
Otherwise, user has no way to download the vpn app from Play Store,
and never be able to gain control of the network again.
2. Allow user to connect other vpn app.
Implementation
1. Switch off always-on mode if the package gets removed.
2. Restart always-on mode if the package gets replaced/upgraded.

- add a new field: provisioningNotificationEnabled from NetworkMisc. set
to false if we want to hide "sign in" notification and placed
carrier-specific notification instead. it is set on connect, once set,
it is carrier-app's responsibility to post new UI to users
- rework on the interaction between carrier app and framework
- code cleanup
- unit test support

Previously this was included in the log messages from NetworkMonitor
but that has been removed (ag/944107), making it frequently impossible
to know what network the logs apply to as there may be no way to
correlate NetIDs to WiFi SSIDs or Cellular networks if the log has wrapped.
Bug: 26075613
Change-Id: I2e3cd41fffb616ab9f855cb16790360bd3414793
Cause: It revoked the user consent of the vpn app without reseting always-on vpn.
In addition, prepareVpn sets legacy vpn as the current package, the state in
Vpn.class is broken, as it thought the current always-on package is legacy vpn,
(mAlwaysOn is only for app vpn, not for legacy vpn). As a result, prepareVpn rejects
all VpnService.prepare.

When disconnecting from a default network X and falling back on another
connected network Y as the new default, ConnectivityService was
attempting to record this event as a X -> Y "atomic" transition.
In practice the default network connectivity is actually lost and
recovering default network takes some non-zero time.
This patch changes the event recording to always record disconnection as
X -> 0 events. At the same time, if there is a fallback network that is
elected as the new default ConnectivityService will also record a 0 -> Y
event.
This patch also improves pretty-printing of DefaultNetworkEvent.
Extract from $ adb shell dumpsys connectivity_metrics_logger --events
17:51:00.086: DefaultNetworkEvent(0 -> 100:CELLULAR)
17:51:25.232: DefaultNetworkEvent(100:IPv4 -> 101:WIFI) # wifi goes on
17:51:44.064: DefaultNetworkEvent(101:DUAL -> 0) # wifi goes off

NET_CAPABILITY_NOT_METERED to the capabilities.
