This patch ensures that subtract() between two NetworkStats object will
return a delta with no negative entries in all cases.
When the stats delta contains some negative values, there are clamped to
0. Some logging is added when this happens.
This is what's expected by NetworkStatsHistory#recordData().

Any NetworkRecommendationProvider bound to by the system must have
access to location (i.e. it holds the location permission and
location is enabled on the device).
If the location permission is revoked then the binding will be
disconnected and the system will revert to the default network
recommendation provider (if set and valid). If location access
is disabled on the device then the binding will be disconnected
but the system won't fall back to the default provider (because
it won't have location either), instead the current provider will
be re-enabled when location access is enabled again.

This patch simplifies argument validation in NsdManager public api and
regroup duplicated validation into common methods.
This makes stack traces more actionable as now specific errors will
cause the api to throw exception from specific methods, whereas before
IllegalArgumentException would be thrown from inside the same api method
for different reasons.
This patch also includes a couple of other small cleanups.

Clean up SubscriptionPlan, add docs, and expose as public API.
Deprecate older constants in CarrierConfigManager, and point users
towards new API. (The goal of CarrierConfigManager is to express
key/value pairs that are identical for all users on a particular
carrier, not to configure details that vary between users.)
Since a CarrierService may itself not have access to the plan
details, allow them to "delegate" the capability to configure plans
to another package name.
Factor out new RecurrenceRule class which is used by both
NetworkPolicy and SubscriptionPlan internally. Polish it to support
arbitrary periods, and continue to test it through NPMST.

Always-on VPN is a feature introduced in N. Since then, all VPN apps
targeting N+ are assumed to support the feature, and the user or the DPC
can turn on / off always-on for any such VPN app. However, a few VPN
apps are not designed to support the always-on feature. Enabling
always-on for these apps will result in undefined behavior and confusing
"Always-on VPN disconnected" notification.
This feature provides a new manifest meta-data field through which a VPN
app can opt out of the always-on feature explicitly. This will stop the
always-on feature from being enabled for the app, both by the user and
by the DPC, and will clear its existing always-on state.
A @hide API is provided to check whether an app supports always-on VPN.
Documentation is updated to reflect the behavior change.

Add new SubscriptionPlan API to describe the various types of carrier
data plans. Internally the OS will only use the first plan for
driving policy, but it will blindly plumb through the details for
Settings to display any secondary plans.
As part of getting Settings ready to roll towards SubscriptionPlan,
reduce references to NetworkPolicy internal fields. All usage cycle
details are now obtained from an Iterator which converts to
SubscriptionPlan under the hood.
Replace all data usage cycle calculation with new SubscriptionPlan
implementation, and retrofit large suite of existing tests to
exercise and verify the new logic.
Offer a debugging property that can be used to return "fake" plan
examples for testing.

For a long time we've had a nasty tangled dependency between Wi-Fi
and NPMS, since they both persisted different details for configured
networks. As part of preparing for new carrier data plan APIs, move
the tracking of meteredness over to WifiConfiguration.
This also cleans up how meteredness is communicated through
NetworkAgents to rely completely on NET_CAPABILITY_NOT_METERED by
removing the metered flag on NetworkInfo, which has caused confusion
and staleness.
Migrates any existing user-configured metered networks over to
WifiConfiguration once the device finishes booting.
Remove support for NetworkQuotaInfo, since this information can no
longer be made available to apps. Frustratingly, some apps are
using it, so keep the object around returning stub values, and shame
them in the logs.

This patch adds a InitialConfiguration class to IpManager for specifying
IP information in IpManager ProvisioningConfiguration at IpManager
startup.
At the moment this InitialConfiguration is not used, but is validated in
startProvsiioning if ProvisioningConfiguration includes one. It will be
integrated into IpManager IP provisioning logic in follow-up patches.
This patch also includes an example of data driven unit tests using a
table of test case. The highlights of this methodology are:
1) easy extensibility for new test case,
2) rich and informative error messages,
Unfortunately Java support for inlined data structure literals is poor
and some companion static methods for data generation are required for
enabling this methodology.

(cherry pick from commit 557e0c38b9)
This patch allows to use TYPE_NONE for the legacy network type variable
of NetworkInfo. This usage is "safe" with respect to legacy APIs using
network types as most of them already returns null or do nothing for
TYPE_NONE.
Of the existing APIs in ConnectivityManager that accept a network type
argument, those which were already returning null or doing nothing for
TYPE_NONE are:
getNetworkInfo(int)
getNetworkForType(int)
stopUsingNetworkFeature(int, String)
networkCapabilitiesForType(int)
requestRouteToHostAddress(int, InetAddress)
reportInetCondition(int, int)
isNetworkSupported(int)
getLinkProperties(int)
Only setProvisioningNotificationVisible needs an additional guard
against TYPE_NONE.
