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.

Reduce persist threshold for lower warning/limit. Default is 2MB persist threshold, but even that can be substantial for devices on 100MB/month plans.

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.

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.

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.

Foreground/background network stats using sets. Teach NetworkStats about "counter sets" coming from kernel, and use them to track usage in foreground/background.

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.
