Lightweight checkin output for network stats.
Define and print a compact version of network statistics when dump
is requested with the "--checkin" flag. Defaults to last 24 hours,
but included data can be tweaked with various flags.
Groups together detailed network identities into larger umbrella
terms like "mobile" and "wifi."

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
the first atomic XT bucket, and adds a Settings.Secure flag to force
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.

Foreground/background network stats using sets.
Teach NetworkStats about "counter sets" coming from kernel, and use

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

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.

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.

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.
