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.

When an app is restricted in the background, don't allow them to
start using metered network features. With this change they can
still use network features when in foreground. This avoids situation
where apps can bring up APNs which they are unable to use.

Add method to parse new iface_stat_fmt proc stats, or return null
when kernel support is unavailable. Add test and remove older, unused
parsing code. Create new "xt" recorder to persist the new xtables
counters when available.
Add SSID support to NetworkIdentity to fix policy tests.

and the routes are auto-removed. Change the log to VDBUG so standard

Add networkId field to NetworkIdentity to identify Wi-Fi networks by
SSID. Add support for policies without usage cycles.
Only apply mobile policies when SIM state is ready, which is cleaner
than just checking for airplane mode. Also avoids creating no-op
default policies when subscriberId is null.

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.

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.

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.
