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. This change gradually reduces the
persist threshold up to 8x lower (256kb outstanding) based on lowest
active policy.

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.
