Migrate network stats from removed users.
When a user is removed, migrate all network stats belonging to that
user into special UID_REMOVED bucket. Also removes those stats from
kernel to avoid double-counting if another user is created.

Correct proc file reader, optimizations.
Moved away from BufferedReader, which only reads the first 8KB of
some proc files because it aggresively fills its buffer. Optimized
proc parsing, now double the speed. Tests to cover.
Log when NetworkStats counters roll backwards when subtracting, and
optimizations around findIndex(). When system removes UID, also
remove from last stats snapshot to avoid xt counters from rolling
backwards.

Move battery stats to xt_qtaguid for data stats.
Replace TrafficStats calls by reading values from xt_qtaguid kernel
module. To keep BatteryStatsImpl changes lightweight, cache recently
parsed stats. Tracks mobile ifaces from ConnectivityService.
Refactor xt_qtaguid parsing into factory outside of NMS. Add stats
grouping based on UID, and total based on limiting filters like iface
prefix and UID.

Track xtables summary, move tether stats, time.
Begin tracking xtables summary of data usage to compare with values
reported from /proc/net/dev. Roll tethering directly into UID stats
to trigger UID stats persisting when crossing threshold.
Include xtables summary and authoritative time in samples.

Register for kernel global data usage alerts.
Instead of polling every 15 minutes, register for alerts that trigger
when system-wide traffic passes a threshold. Still mixed with polling
to persist UID stats, but relaxed to 30 minutes. Currently watches
for every 512kB.
Make persistence decision separately for network versus UID, and use
total delta bytes when making decision. Use light bootstrap during
systemReady() instead of heavy poll, which had been force-loading all
UID data unnecessarily.

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.

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.

Return stats from inactive ifaces, packet counts.
When an iface goes inactive, xt_qtaguid maintains historical counters
instead of discarding. Now reading and returning those values in
NetworkManagementService summary calls. Tests to verify stats are
returned.
Modify NetworkStats to include rxPackets and txPackets values, and
move to Entry to eventually hide internal storage details.

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.

Growable NetworkStats object instead of builder.
NetworkStats now grows in place with arraycopy() instead of callers
needing to know record count a priori. Better growth calculation for
both NetworkStats and NetworkStatsHistory; 50% each time. Better
estimates of buckets needed in calling services.

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.

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.

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.
