Improve multi-user broadcasts.
You can now use ALL and CURRENT when sending broadcasts, to specify
where the broadcast goes.
Sticky broadcasts are now correctly separated per user, and registered
receivers are filtered based on the requested target user.
New Context APIs for more kinds of sending broadcasts as users.
Updating a bunch of system code that sends broadcasts to explicitly
specify which user the broadcast goes to.
Made a single version of the code for interpreting the requested
target user ID that all entries to activity manager (start activity,
send broadcast, start service) use.

Transition from DEV network stats to XT.
When XT stats are available, transition to prefer them over DEV,
since they aren't subject to hardware driver bugs. Only switches at

back to DEV if needed. Includes tests to cover transition.
Fix tests where device overlay would change which network types
reflected data usage. Test both history and summary APIs. Fixed
collection timestamps to reflect full buckets.

Move network stats to FileRotator pattern.
Split existing network stats into two separate classes: a recorder
which generates historical data based on periodic counter snapshots,
and a collection of historical data with persistance logic.
Recorder keeps a pending history in memory until outstanding data
crosses a specific threshold. Persisting is handled through a given
FileRotator. This pattern significantly reduces disk churn and
memory overhead. Separate UID data from UID tag data, enabling a
shorter rotation cycle. Migrate existing stats into new structure.
Remove "xt" stats until iptables hooks are ready. Avoid consuming
Entry values when recording into NetworkStatsHistory. Assign
operation counts to default route interface.
Introduce "Rewriter" interface in FileRotator with methods to enable
rewriteAll(). Introduce IndentingPrintWriter to handle indenting in
dump() methods.

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.
