Like a normal (foreground) request, a background request is only
satisfied by one network and will keep that network up. Unlike a
foreground request, when a network only has background requests,
it will linger, and after lingering is complete, it will become
a background network.
Future CLs will cause the system to treat background networks
differently, e.g., by requiring different permissions.

Add an IPv6TetheringCoordinator to TetheringMaster StateMachine, which
receives and processes NetworkState updates and passes the necessary IPv6
information to the revelant TetherInterfaceStateMachine.
Add an IPv6TetheringInterfaceServices to TetherInterfaceStateMachine, which
is responsible for adding local network routes and managing an IPv6

This patch partially undoes ag/869831 (Change-Id:
Ia42ed7aefaebd8caf3eada8e42b6cb7a940d7647) so that ConnectivityManager
does not remove callbacks from its internal request-to-callback map at
unregistration, but instead let the singleton CallbackHandler do it when
receiving a CALLBACK_RELEASED from ConnectivityService.
ag/869831 was thought to fix b/26749700 that reported a callback leak
from sNetworkCallback, but a finer analysis of the code shows that
callbacks were correctly removed by the CallbackHandler before
ag/869831. There was therefore no callback leak.

http://ag/1194313 broke unregisterNetworkCallback because the
system does not parcel the type of the request back to the app.
So when the app calls unregisterNetworkCallback, the
NetworkRequest that's passed in does not have a type and thus
doesn't match the request in mNetworkRequests.
Fix this by parceling over the type as well.
This was not caught by the unit test because the unit test all
runs in the same process with no parceling.

- 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

By changing some member refs into arguments and having one of the
functions create the UID range instead of adding to mVpnUsers.
This will be useful for other layers of UID filtering like having
UIDs explicitly blocked from the VPN.
Deleted one broken line of code that cleared the status intent when
a restricted profile is removed. Other than that, this commit shouldn't
change any behaviour. If it does, that's a bug.

When a job will eventually run in the foreground, the internal
scheduling needs to ignore any background network restrictions when
satisfying constraints. This also means the job should ignore the
current device doze state, since the requesting app could get the
same behavior by starting their own foreground service.
Always dispatch network policy changes to ConnectivityService first
to ensure that it has up-to-date information. Fix bugs around data
saver that were causing networks to not be marked as BLOCKED for
background apps; before this fix apps would have been spinning in
internal connectivity loops, thinking that the network was actually
connected when the kernel was actually blocking their traffic.
Offer new ConnectivityService method overloads to ignore the blocked
state for a specific UID.
Print unsatisfied job constraints to aid debugging.

Place helper map for callback field names into a holder. This avoids
the reflective calls in static initialization of ConnectivityManager
in the common (non-debug) case, which means the class can be
compile-time initialized. Also saves the storage necessary (both
the storage array as well as the reflection metadata).
Follow-up to 7e28683228.

To support moving DownloadManager, add new JobScheduler network type
constraint that matches "any network except roaming." Also add an
API to get a specific JobInfo by ID.
Since the default network can be different on a per-app basis, and
individual apps may be blocked due to app standby, evaluate job
connectivity constraints on a per-UID basis. To implement this
cleanly, add NetworkInfo.isMetered() to match the isRoaming() API.
Add new DownloadManager APIs to support charging and device idle
constraints, which are plumbed through to JobScheduler under the
hood when scheduled.
Add filtering to JobScheduler dumpsys to omit noisy details for
packages the caller isn't interested in.

The JavaDoc for many of the requestNetwork and
[un]registerNetworkCallback APIs incorrectly mentions the
PendingIntent version of the APIs instead of the NetworkCallback
version.
Also fix a minor issue in the registerDefaultNetworkCallback
JavaDoc: the default network request is an implementation detail,
so don't mention it. Instead, talk about the "system default
network".

There's a few advantages to having ApfFilter in IpManager:
1. If things go wrong, crashing a particular transport is less bad then
crashing ConnectivityService. We also don't want to use
ConnectivityService as a dumping ground for transport-specific logic.
2. This makes implementing WifiManager.MulticastLock a lot simpler and
safer because enabling/disabling it doesn't have to go through the
NetworkAgent, which could risk various races (e.g. installing a filter
into the wrong WiFi network).
3. IpManager is the ultimate source for LinkProperties for a particular
transport and since ApfFilter uses the LinkProperties it's better to
have it closely paired with the IpManager. Likewise, ApfFilter needs
to know the APF capabilities of the transport, so having it in
the transport avoids having to parcel this information through the
NetworkAgent.
