API to adjust network stats. DO NOT MERGE.
Enables system apps to correctly account network usage performed on
behalf of another application.

Reduce persist threshold for lower warning/limit.
Default is 2MB persist threshold, but even that can be substantial
for devices on 100MB/month plans. This change gradually reduces the
persist threshold up to 8x lower (256kb outstanding) based on lowest
active policy.

Move TrafficStats iface counters to xt_qtaguid.
Use xt_qtaguid iface_stat_all counters, which are monotonic during
a single boot.
Track all ifaces associated with mobile networks since boot, and
move TrafficStats to using these ifaces. This will include usage of
networks omitted from config_data_usage_network_types, specifically
on devices that recycle network interfaces across APNs.
Split wildcard template matching, and move NetworkStatsService to
use mobile wildcard when logging stats.

INetworkStatsSession with lifecycle for caching.

lifecycle, which keeps a strong-reference chain to any fully loaded
NetworkStatsCollection histories.

Foreground/background network stats using sets.
Teach NetworkStats about "counter sets" coming from kernel, and use
them to track usage in foreground/background. Add AID_NET_BW_ACCT to
system_server so it can control counter sets.
Move to composite key of NetworkIdentitySet, UID, set, and tag when
recording historical usage. Persisting still clusters by identity,
since that is heaviest object.
Request async stats poll during systemReady() to bootstrap later
delta calculations. Reset kernel counters when UID removed. Update
various tests.

Network stats with varint, omit parcel fields.
Persist NetworkStatsHistory using variable-length encoding; since
most buckets have small numbers, we can encode them tighter. Initial
test showed 44% space savings. Also persist packet and operation
counters.
Let NetworkStatsHistory consumers request which fields they actually
need to reduce parcel overhead.
Tests for verify varint and history field requests, also verify end-
to-end by persisting history into byte[] and restoring. Expose
bandwidth control enabled state. Extend random generation to create
packet and operation counts. Moved operation counts to long.
Fix bug that miscalculated bytes since last persist, which would
cause partial stats loss when battery pulled.

Add operation counts to network statistics.
Provide API to increment "operation counts" for a UID and tag, used
to eventually derive bytes/operation stats. Internally is stored at
network layer, but should belong at data layer. Switch profiling
to use data layer stats, which are emulated by summarizing network
layer details.
Read packet counts from new /proc/ columns and collect them into
NetworkStatsHistory. Prevent double-counting by ignoring values from
first snapshot. Watch for duplicate /proc/ entries. Update tests
to verify packet and operation counters.

Migrate bandwidth control to NMS, omit history.
Both stats and policy make NMS calls that depend on bandwidth control
being enabled, so move enable/disable into NMS and drop calls when
disabled. This avoids throwing heavy ISE exceptions when disabled.
Only include recent data when writing NetworkStatsHistory as part of
dumpsys call. Introduce manual poll event for Settings UI.

Persist "tagged" network stats along with UIDs.
Now stores tags other than TAG_NONE (0x0), which are useful for app
debugging. Combine UID and tag together into single long key, and
expose tag data through AIDL when requested. Change NMS to track
TAG_NONE as total UID traffic, matching the kernel definition.
Added TAG_MAX_HISTORY to control how long tag-granularity statistics
are stored; overall UID usage is still kept for UID_MAX_HISTORY. Fix
bug to trim NetworkStatsHistory outside normal polling loops to catch
non-active networks and UIDs.
Test to verify UID and tag packing, and to verify that UID traffic on
two networks are combined to match MOBILE_ALL template.

Read "qtaguid" network stats, refactor templates.
Teach NMS to read qtaguid stats from kernel, but fall back to older
stats when kernel doesn't support. Add "tags" to NetworkStats entries
to support qtaguid. To work around double-reporting bug, subtract
tagged stats from TAG_NONE entry.
Flesh out stronger NetworkTemplate. All NetworkStatsService requests
now require a template, and moved matching logic into template.
Record UID stats keyed on complete NetworkIdentitySet definition,
similar to how interface stats are stored. Since previous UID stats
didn't have iface breakdown, discard during file format upgrade.

Interface-level network policy, persist policies.
Define NetworkPolicy as cycle-reset day and warning/limit values, and
set/get through NetworkPolicyManager. Watch ConnectivityManager for
network connection events, and apply quota rules based on matching
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.

Persist network stats using AtomicFile.
Implements read/write of network stats using AtomicFile, along with
magic number and versioning. Stores in "/data/system/netstats.bin"
for now. Tests to verify that stats are persisted across a simulated
reboot, and to verify that TEMPLATE_WIFI is working.
Fixed bug where kernel counters rolling backwards would cause negative
stats to be recorded; now we clamp deltas at 0.

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.
