Process AMS events in NetworkPolicy handler.
When a process changes foreground status or dies, NetworkPolicy
updates its internal state with a lock held. In cases where there
is contention, this can block the AMS handler and prevent other
events, such as broadcasts, from being dispatched.
This change moves the incoming AMS events to an existing internal
NetworkPolicy handler thread, where they can execute without
blocking AMS.

Instead of polling every 15 minutes, register for alerts that trigger

interfaces. Policy service matches based on strong identity to support
IMSI-specific policy values.
Calculates remaining quota based on current stats recorded since the
last reset cycle day. Tests to verify edge cases around February.
Persist network and UID policies in XML, and restore on boot.

Map network identity using ConnectivityService.
Instead of deriving network identity based on raw subsystem broadcasts,
listen for updates from ConnectivityService. Added atomic view of all
active NetworkState, and build map from "iface" to NetworkIdentity set
for stats tracking.
To avoid exposing internal complexity, INetworkStatsService calls use
general templates. Added TelephonyManager mapping to classify network
types using broad labels like "3G" or "4G", used to drive templates.
Cleaned up Objects and Preconditions.

Collect historical network stats.
Periodically records delta network traffic into historical buckets to
support other services, such NetworkPolicyManager and Settings UI.
Introduces NetworkStatsHistory structure which contains sparse, uniform
buckets of data usage defined by timestamps. Service periodically
polls NetworkStats and records changes into buckets. It only persists
to disk when substantial changes have occured. Current parameters
create 4 buckets each day, and persist for 90 days, resulting in about
8kB of data per network.
Only records stats for "well known" network interfaces that have been
claimed by Telephony or Wi-Fi subsystems. Historical stats are also
keyed off identity (such as IMSI) to support SIM swapping.

Tests for NetworkPolicyManager rule generation.
Verifies that policy changes trigger rule updates that respect current
foregroundActivities status. Also verifies logic that promotes a UID
based on its most-foreground PID. Verifies that policy changes result
in immediate rule changes.
Also verifies that BACKGROUND_DATA_SETTING_CHANGED broadcasts are sent
by policy changes.

Teach NetworkPolicyManager how to dumpsys itself.
Includes details on all internally known UIDs, which can be used for
debugging purposes.

Policy and rules work for ConnectivityManager.
Teach ConnectivityManager about UID-specific rules derived from policy,
such as rejecting network traffic on "paid" interfaces. Calls that
return NetworkInfo now filter based on any REJECT rules in effect for
the calling UID. (Added uid parameter if callers that still want all
interfaces.)
Changed NetworkPolicyManager to derive rules based on current policy
combined with PowerManager and ActivityManager status, which it passes
to ConnectivityService for eventual enforcement through netd. When
rules change the usability of a NetworkInfo for a specific UID, it also
dispatches CONNECTIVITY_ACTION broadcasts to that UID. Combined paid
and background policy together to match current working definition.

Observe screen on/off events in NetworkPolicy.
The POLICY_REJECT_BACKGROUND policy requires that network traffic be
blocked when a UID goes into the background. Even if the UID has an
activity in the foreground, it's considered "background" if the screen
is turned off.
This changes watches for SCREEN_ON/OFF broadcasts, and rule generation
now observes screen state. It also introduces an observer pattern so
that ActivityManager doesn't directly know about NetworkPolicy, and
moves the service management into SystemServer.

APIs to profile network usage for current UID.
Added startDataProfiling() and stopDataProfiling() to TrafficStats,
which can be used by apps to measure network usage delta between two
points in time. Currently takes two NetworkStats snapshots and returns
delta, which will eventually include tag-level granularity. Added
tests for NetworkStats delta subtraction.
Added NMS.getNetworkStatsUidDetail() that returns stats for specific
UID. Always gives stats access for the calling UID, otherwise enforces
that caller has permission. Fix readSingleLongFromFile(), since
/proc/ files don't have well-defined lengths.

First pass at NetworkPolicy and activity tracking.
New system service that maintains low-level network policy rules and
collects statistics to drive those rules. Will eventually connect to
netfilter kernel module through NetworkManagementService and "netd".
Begin tracking foreground activities in ActivityManagerService, which
is updated as part of OOM adjustment. Eventually a network policy of
POLICY_REJECT_BACKGROUND will reject network traffic from background
processes.
